Jet Pack

About Jet Pack

Jet pack, rocket belt, rocket pack, and similar names, are various types of device, usually worn on the back, that use jets of escaping gases to allow the user to fly.

The concept of these devices emerged from science fiction in the 1920s and popularised in the 1960s as the technology became a reality. Currently the only practical uses of the jet pack has been Extra-vehicular activity for astronauts and despite decades of advancement in the technology, the challenges of the Earth's atmosphere and Earth's gravity and the human body (not being suited to this type of flight) remain an obstacle to its potential use in the military and as a means of personal transport.

In 1960, Bell Rocketbelt was presented to the public. The jet of gas was provided by a hydrogen peroxide powered rocket but the jet can also be provided by a turbojet engine, a ducted fan, or other kinds of rockets powered by solid fuel, liquid fuel or compressed gas (usually nitrogen).
