Oop, I realized I never actually posted about this, but!

Anyone remember my separated Donnie au? Code name: Violet skies? Well I'm remaking it! Rewriting it, even !!

Here's Foot Recruit/aka Donnie!

Draxum, quite begrudgingly, ends up raising the four turtles with Splinter: whom saved him when a part of the lab's roof collapsed, while he was holding onto two of the turtles. Splinter brought the both of them to the sewers, and it all happened from there.

The turtles grew up not too different, safe for extra actual training and knowledge of both the hidden city and things mystic; until Leo and Donnie turned 14. Donnie went out one day with Raph, and didn't come back.

Two years after his disappearance, when the series events begin, they find him in the Foot Clan. Now called just Foot Recruit, with no memory of them — and a good 6 years worth of memories of living with the foot clan.

Crash!

The NHTSA funded Viking VI after its 40 MPH barrier crash test at Dynamic Science in Phoenix, Arizona. (Impact was actually at 41.2 MPH - they had never tested a car that lightweight before and misjudged the settings of the test catapult).

Also like a Phoenix, Viking VI would rise again too. The center chassis tub was undamaged after the test, so it was rebuilt as Viking VI MK II.

Today it is the only existing example of the decade-long series of Experimental Safety Vehicles (ESVs) funded by the U.S. Department of Transportation. In this program, experimental car designs from Fairchild-Fairchild, AMF, GM, Ford, Chyrsler-Calspan, Mini Cars Inc. and the VRI were funded to create the worlds safest car. This was the U.S. DOT's 1970s decade long "moon shot" to jump start safer car designs.

Viking VI was the last car funded in the DOT ESV project. At the close of the program, no manufacturer had yet met the requirement for the lightest category of design criteria (the earliest generation of ESVs topped the test weight scale at near 6000 lbs!). The VRI delivered, and Viking VI was presented for testing at an empty weight of 1250 lbs.

Viking VI is unique as it is the only Viking car to have fully enclosed wheels on all four corners.

Power was supplied by a 1.6 litre Subaru Boxer-4 with selectable two-cylinder/four-cylinder operation. The GM valve disabler form the Cadillac 4-6-8 system was adapted for this purpose.

Later a Subaru 1.0 litre three-cylinder from a Japanese market kei car was installed, and that is how it remains powered today.

What We Learned from Flying a Helicopter on Mars

The Ingenuity Mars Helicopter made history – not only as the first aircraft to perform powered, controlled flight on another world – but also for exceeding expectations, pushing the limits, and setting the stage for future NASA aerial exploration of other worlds.

Built as a technology demonstration designed to perform up to five experimental test flights over 30 days, Ingenuity performed flight operations from the Martian surface for almost three years. The helicopter ended its mission on Jan. 25, 2024, after sustaining damage to its rotor blades during its 72nd flight.

So, what did we learn from this small but mighty helicopter?

We can fly rotorcraft in the thin atmosphere of other planets.

Ingenuity proved that powered, controlled flight is possible on other worlds when it took to the Martian skies for the first time on April 19, 2021.

Flying on planets like Mars is no easy feat: The Red Planet has a significantly lower gravity – one-third that of Earth’s – and an extremely thin atmosphere, with only 1% the pressure at the surface compared to our planet. This means there are relatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can interact to achieve flight.

Ingenuity performed several flights dedicated to understanding key aerodynamic effects and how they interact with the structure and control system of the helicopter, providing us with a treasure-trove of data on how aircraft fly in the Martian atmosphere.

Now, we can use this knowledge to directly improve performance and reduce risk on future planetary aerial vehicles.

Creative solutions and “ingenuity” kept the helicopter flying longer than expected.

Over an extended mission that lasted for almost 1,000 Martian days (more than 33 times longer than originally planned), Ingenuity was upgraded with the ability to autonomously choose landing sites in treacherous terrain, dealt with a dead sensor, dusted itself off after dust storms, operated from 48 different airfields, performed three emergency landings, and survived a frigid Martian winter.

Fun fact: To keep costs low, the helicopter contained many off-the-shelf-commercial parts from the smartphone industry - parts that had never been tested in deep space. Those parts also surpassed expectations, proving durable throughout Ingenuity’s extended mission, and can inform future budget-conscious hardware solutions.

There is value in adding an aerial dimension to interplanetary surface missions.

Ingenuity traveled to Mars on the belly of the Perseverance rover, which served as the communications relay for Ingenuity and, therefore, was its constant companion. The helicopter also proved itself a helpful scout to the rover.

After its initial five flights in 2021, Ingenuity transitioned to an “operations demonstration,” serving as Perseverance’s eyes in the sky as it scouted science targets, potential rover routes, and inaccessible features, while also capturing stereo images for digital elevation maps.

Airborne assets like Ingenuity unlock a new dimension of exploration on Mars that we did not yet have – providing more pixels per meter of resolution for imaging than an orbiter and exploring locations a rover cannot reach.

Tech demos can pay off big time.

Ingenuity was flown as a technology demonstration payload on the Mars 2020 mission, and was a high risk, high reward, low-cost endeavor that paid off big. The data collected by the helicopter will be analyzed for years to come and will benefit future Mars and other planetary missions.

Just as the Sojourner rover led to the MER-class (Spirit and Opportunity) rovers, and the MSL-class (Curiosity and Perseverance) rovers, the team believes Ingenuity’s success will lead to future fleets of aircraft at Mars.

In general, NASA’s Technology Demonstration Missions test and advance new technologies, and then transition those capabilities to NASA missions, industry, and other government agencies. Chosen technologies are thoroughly ground- and flight-tested in relevant operating environments — reducing risks to future flight missions, gaining operational heritage and continuing NASA’s long history as a technological leader.

You can fall in love with robots on another planet.

Following in the tracks of beloved Martian rovers, the Ingenuity Mars Helicopter built up a worldwide fanbase. The Ingenuity team and public awaited every single flight with anticipation, awe, humor, and hope.

Aircraft engine types ✈️

✈️Turbo-Shaft: Used in helicopters and some fixed-wing aircraft, it features a compressor, combustion chamber, and turbine. The turbine drives a power shaft via a free (power) turbine, which powers the rotor or propeller through a gearbox, rather than producing direct thrust. Exhaust gases are expelled separately.

✈️Turbo-Prop: Similar to a turbo-shaft, it powers a propeller via a gearbox. Air is compressed, mixed with fuel, and burned in the combustion chamber. The turbine extracts energy to drive the propeller, with some exhaust thrust. It’s efficient for low-speed, short-range flights.

✈️Turbo-Fan: Common in commercial jets, it has a large fan at the front, high- and low-pressure compressors, a combustion chamber, and turbines. The fan accelerates air around the core (bypass air) for thrust, while the core produces additional thrust via exhaust. It’s efficient for high-speed, long-range flights.

✈️Turbo-Jet: An older design, it compresses air, burns fuel in the combustion chamber, and expels exhaust through a nozzle for thrust. It lacks a bypass fan, making it less efficient but capable of high speeds. Used in early jet fighters and some supersonic aircraft.

✈️Ram-Jet: Operates at high speeds (Mach > 1), using forward motion to compress air in the inlet. Fuel is injected and burned in the combustion chamber, and the exhaust is expelled through a nozzle for thrust. It has no moving parts but only works at high speeds.

✈️Scramjet: A supersonic combustion ramjet, designed for hypersonic speeds (Mach > 5). Air enters at supersonic speeds, is compressed, mixed with fuel, and burned in a combustion chamber, with exhaust expelled for thrust. It’s used in experimental hypersonic vehicles.

✈️Rocket: Uses stored propellants (fuel and oxidizer) in a pressure vessel. Propellants are burned in a combustion chamber, and the high-pressure exhaust is expelled through a nozzle for thrust. It operates in space since it doesn’t rely on atmospheric oxygen.

✈️Gas Turbine: Similar to a turbo-shaft, it’s used for power generation or auxiliary power units. Air is compressed, burned with fuel, and the exhaust drives a power turbine, which can power generators or other systems. Bleed valves and discharge ports manage airflow and pressure.

Each engine type is optimized for specific applications, balancing efficiency, speed, and operational environment.

Everlasting Trio Nobody Knows AU DP x DC Part 4

Part 3

(Tim POV! This is a long one 😅)

 Tim almost has it. He's so close to cracking this file he can fucking taste it. He's been fighting this thing for two weeks. It's the most incomprehensible and infuriating code he's ever faced off against, which is fitting considering who gave it to them.

The engineer. THEIR engineer. The engineer they didn't ask for and Tim still isn't sure how they got, and the single biggest mystery in Tim's fucking life right now.

See, a significant amount of Bat gadgets at this point are Tim's brainchildren. He imagines them, he designs them, he workshops and tests them.

A few months ago, he'd had a pouch on his utility belt full of experimental pellets meant for slowing down fleeing vehicles. They were designed to break when run over and the compound inside would expand into durable, sticky foam that would ensnare tires.

He'd tested them in the cave.

He had not been prepared to take one hit to that side and have to frantically divest himself of that pouch before he became Gotham's latest foam based cryptid. 

His family had laughed themselves silly at him even as he broke off in pursuit of the drug runners he'd been fighting.

When Tim had doubled back expecting a mess to clean up and pellets to rework? It had been gone. All of it. The foam, the pellets, the pouch of his utility belt.

A serious problem, because who knows who got their hands on that?

Then it had shown back up.

That is to say, Gordon had called them because he found a pouch with a note labeled ‘for Red Robin’ sitting on the stand of the Bat Signal and didn't dare touch it.

After making sure it wasn't a bomb or some kind of biological weapon, Tim had opened the pouch - his own belt pouch - and found pellets. New pellets. Different pellets.

The note just read, “As funny as that was to watch, I fixed them for you. No more premature sploogage on the job. :3 P.S. here's a recipe for solution to dissolve future intentional discharges.”

They'd been right, too. The new pellets were tested (in case THEY were a bomb or biological weapon) and they'd been just strong enough to safely transport but still break when under the pressure of tires. Even the foam was more effective, and the spray Tim synthesized from that stupid recipe had worked like a dream.

What. The fuck.

This person not only improved his design and came up with a dissolution agent from scratch in days, they'd been watching without him knowing and made off with the original pellets without anyone noticing.

This was either a rogue in the making or someone they wanted on their side, and either way they needed to be found.

So Tim had done the obvious.

He'd put together a lockbox of money for the product they'd been given, loaded it with no less than ten (10) bat trackers and a note thanking their mysterious benefactor and requesting to meet up. He'd exploded a foam pellet on a rooftop and left the box on it in the hopes they'd notice and find it, then hung around far enough to not be seen and close enough to beat feet as soon as the trackers started moving. 

They did not start moving. They all went offline simultaneously. 

Tim has never moved so fast in his life, and yet by the time he got to the rooftop there was a pile of foam and nothing else. Not even a trace of whoever took the lockbox.

The next day, there was a ping of one (1) tracker that led them to a note thanking him for the money, refusing to meet, and asking if they'd considered certain improvements to their grapples with schematics for said designs.

Thus started the most bizarre and infuriating chase through notes, money, helpful designs and disappearing trackers Tim has ever been a part of.

Last time, the engineer had left them a USB stick and a note claiming that since they really wanted to know about him so bad, they could have the information on the USB if they could crack the encryption on the zip file inside.

Obviously they screened heavily for viruses or backdoors, but long story short Tim has been trying to crack the fucking thing for two weeks and refuses to let Oracle help. It's personal. It's a matter of pride. 

He could swear the code itself has actively been sabotaging his attempts to hack it, which is, you know. Impossible. 

Ping!

Tim blinks, looking over at the map on another monitor of the Bat computer. 

“Motherfucker-”

He taps into Duke’s comms. This is the first time this has ever happened during the day shift, he wasn't expecting it.

“Signal! I need you on the roof of the warehouse on the corner of Fifth and Everest - a tracker just came online.”

Another thing that infuriates Tim. You can't just turn Bat trackers on and off. They're activated, and then they either stay active or they're destroyed. They can't be turned off and then reactivated.

And fucking yet.

Duke groans, but his own tracker starts making its way in that direction.

“Dude. He's gonna be long gone by the time I get there. He always is.”

“He can't run from me forever,” Tim insists. “I'm almost in this damn file, and I am going to find him and dangle him off a roof from his ankles for giving us this runaround, so help me God.”

“Uh huh,” Duke deadpans. “Sure you are. I'm almost there, and- oh look! A note. What a surprise!”

Tim hears Duke touch down on the rooftop, eyes on the code on his screen while his brother clears his throat and reads aloud.

“Ahem- ‘Good morning, sunshine!’ - guess that's me - ‘I hear some bats and birds have been murdering tires at an alarming rate with the way they drive their bikes-’”

Tim freezes. He's not listening anymore.

“Signal.”

“‘- and that just can't be good for business. Nobody wants a bald tire ruining a chase. So boy do I have the thing for you-”

“Signal!”

“What?”

“I got it.”

“Huh? Got what?”

“I cracked his file. I got it.”

Tim is staring, wide eyed and full of a mixture of elation and trepidation at the contents of the zip file. It's a single text file titled, ‘Wow! You did it!’

“Oh, shit? Well? What's in it?”

Tim swallows, mouse hovering over the file. He takes a deep breath, then double clicks.

The file opens.

Tim blinks.

“Red Robin? What's in it?”

Tim scrolls slowly down, disbelief and horror dawning across his face. “Oh my God.”

“What? Come on, man, talk to me.”

Tim scrolls further.

“Oh. My God.”

“Red? Red Robin, you're scaring me, man.”

Tim puts his face in his hands. Voice muffled, he responds.

“Duke.”

“...Red? You okay?”

“No.”

“No?”

“It's the entire Bee Movie script.”

Silence reigns for a solid five seconds before Duke breaks and descends into raucous, hysterical laughter.

Even muffled by his own hands, Tim's scream of rage scares the bats in the cave into a tizzy.

The Fentonworks Mega-Lab.

So! AU where the Fentonworks Labs actually stretch Miles upon Miles below the City of Amity Park.

It started when the Fentons wanted to add a simple addition to the original Lab when they ran out of space to store their more dangerous weapons. They didn't want their (at the time) young children getting their hands on their experimental Weaponry, it could blow up in their faces!

So they built a different Wing of the Lab to hold all those Inventions.

Then they ran out of space and added a few extra Storage Rooms. But then they decided it was a hassle to have to carefully transport their Dangerous Inventions all the way to the Storage Rooms, and built a Lab specifically for Dangerous Experiments near that same Section. Then that Lab was occupied for a while, and Jack wanted to start a different experiment as well, so they built a few more.

In the end they just never stopped building onto their Labs.

There are sections of the Mega-Lab that are entirely walled off because a few of their more unstable Experiments contaminated the area. Walking into them was not recommended, else you could walk out with an extra eye or 5.

In other sections, their Captured Ghosts had taken over a few Labs and created a sort of Mad Max style civilization using their discarded weapons and vehicles.

In another, all Ghosts became Humans and all Humans became Ghosts. That was a weird one, to this day they still didn't understand how they pulled that off.

In another, some type of Eldritch Time Ghost had been born, and now sort of always existed and never existed, and began experimenting with its powers. They nicknamed it Clocky because it liked to carry around a stopwatch.

And so many more. At one point a failed Portal Experiment messed with the internal Space of the entire thing. Now there was literally no way of Mapping it. The Fentons still somehow managed to navigate it perfectly.

When Jazz and Danny grew up, they too learned how to navigate the Labs, which is how Danny managed to show his friends the Portal Experimentation Wing in the first place.

Unfortunately, it wasn't safe for anyone aside from the Fentons to enter the Mega-Labs, so one day when the Fenton Family+friends left town on a Week Long Camping/Road Trip, they put up a few Ghost Shields to keep both Humans out and the Ghosts in.

This drew some unwanted attention after some tourists saw the giant Glowng Green Building in the middle of an Illinois Town, and rightfully called the Justice League.

Now, the Justice League had tried to call the owners of the house, but nobody picked up the phone. (An incident with Jack and a Canoe had knocked most of their phones into the lake. They weren't even at the lake yet.)

When nobody picked up, they decided to investigate personally.

After getting into the House, they quickly found a door labeled "Labs: Do Not Enter (unless it we are late for Dinner)" and went into ignoring all the warnings.

They quickly regretted it.
