This helmet that can significantly help in reducing the number of deaths due to road mishaps in India.

one doesn’t need statistics to conclude that Indian roads are some of the most dangerous in the world, if not the most! Approximately, 27 per cent of deaths caused by road accidents in India are of two-wheeler motorists and a sizeable chunk of it is because of head injuries. The students from IIT-Roorkee have developed an inflatable airbag helmet for two-wheeler motorists.The inflatable airbag helmet was developed by three final year mechanical engineering students at IIT Roorkee – Rajvardhan Singh, Sarang Nagwanshi and Mohit Siddha. The idea has been inspired from inflatable space structures. which are not too expensive .It could be priced somewhere between Rs 2,000.

In simple words, the helmet is basically a collar made out of Kevlar (same material used to make bullet-proof vests) and it houses sensors for lean angle, velocity, acceleration and so on. The moment, the collar detects an impact; it inflates into an airbag and forms a cushioning layer around the head so as to protect from major injuries. The airbag that surrounds the head helps to lessen the impact and peak acceleration which is what harms the head the most.

Regular helmets do not quite distribute pressure in case of an impact and also do not reduce peak acceleration. According to the tests conducted the IIT-Roorkee team, the inflatable airbag helmet reduced the force on the crash test dummy by up to four times on impact as compared to a conventional helmet. Also, the airbag helmet is able to reduce the peak acceleration as well. Experts suggest this could help prevent fatal injuries in times of a road mishap.

  NASA launches world’s small satellite designed by 18-year-old Tamilnadu student

Smallest 3D-printed satellite

India once again broke a global space record by launching the world’s lightest satellite weighing a mere 64 grams, it’s called Kalamsat, designed and developed not by professional space scientists and engineers, but by 18 years old Tamilnadu student Rifath Sharook and his friends.

The tiny satellite, named after Abdul Kalam, was flown by a Nasa sounding rocket and the liftoff was from the space Wallop Island facility around 3pm (IST). Kalamsat was the only Indian payload in the mission.

A satellite made at home

The total flight time of the rocket was 240 minutes. The satellite, assembled at her T.Nagar residence in Chennai, separated from the rocket after spending 125 minutes in the space’s micro-gravity environment.

Specs of the smallest satellite

The satellite, weighing a mere 64 grams, can be held in one’s palm is a 3.8cm cube and its structure is fully 3D-printed with reinforced carbon fiber polymer. It is equipped with a nano Geiger Muller counter which will measure radiation in space.
