A jet pack, rocket belt, rocket pack or flight pack is a device worn as a backpack which uses jets to propel the wearer through the air. The concept has been present in science fiction for almost a century and the first working experimental devices were demonstrated in the 1960s.

Astrogeologist Gene Shoemaker wearing a Bell Rocket Belt while training astronauts. The Bell Rocket Belt is a low-power rocket propulsion device that allows an individual to safely travel or leap over small distances. It is a type of rocket pack.

Most of the ­devices we refer to as jet packs are actually rocket packs, sometimes called rocket belts. The difference between a rocket and a jet is significant. A jet intakes air, compresses it with a turbine and pushes it out the back, mixing it with fuel and combusting it in the process.

A jet pack is a device that allows a single person to fly short distances. The device is also called jetpack, rocket belt, rocket pack or flight pack. The idea has been present in science fiction literature for over a cerntory. First prototypes, and working devices have been built from about the 1960s. There are a few different designs.

2007年6月14日 · Ditch the rocket belt, and build a bona fide jet pack (okay, jet belt). Widgery plans to release the T73 Turbine by the end of the year; it's a $200,000 model that will burn jet fuel,...

Thomas “Larry” Stanley bankrolled it. They built a rocket belt that extended the time aloft from 20 seconds or so to around 30. But the partnership came apart over money. The belt disappeared.

2018年1月2日 · At one time, the Bell Textron Rocket Belt stunned the audiences with its ability to literally make a man fly. Even though the jet pack remains a past success, Bell Helicopter maintains the same goal: to produce the latest and greatest technology that changes the way we think about aviation.

2022年8月16日 · Williams developed the WR19, a small-scale turbo jet engine with a thrust of 1,900 newtons to replace the hydrogen-peroxide rocket. The allowed Moore and the Bell team to achieve a vastly improved 5 minute flight time with the …

2014年3月2日 · Inventors and hobbyists continued the work that Moore began at Bell Aerospace, creating their own variations of the hydrogen peroxide-powered pack, including a later model Jetbelt built by Juan...

This is a Bell No. 2 rocket belt, also known as the Jet Pack or other terms. It is a small personal propulsion device strapped on the back and enables a person to fly short distances using low rocket power produced by a non-combusting gas.
