The Jetpack evo NT consists of three pressure vessels, placed at the pilot's back. These three pressure vessels contain gas and liquids needed as fuel for the rocket propulsion elements of the Jetpack. The back pack rocket is based on a hydrogen peroxide powered engine, which is based on the decomposition reaction of hydrogen peroxide.

Rocket fuel in the form of high purity hydrogen peroxide with a concentration level between 90 and 98 % is used to give the Jetpack the power for lift-off. The Hydrogen Peroxide is brought in contact with a decomposition catalyst, specially developed for the Jetpack evo NT, based on nano structured high temperature composites consisting of palladium and ruthenium having a nano structured surface. Using a nano structured catalyst the reactive surface increases up to 10.000 times in comparison with common silver screens used as a catalyst inside the propulsion of current Jetpacks.

After getting in contact with the Pd/Ru catalyst, the hydrogen peroxide decomposes into superheated steam and oxygen in less a millisecond increasing its volume up to 1500/2000 times at the normal pressure.

Chemistry: The decomposition follows the exothermic chemical reaction

discharging an energy value of 2882 kJ/kg. Due to the exothermic energy release, the reaction products - consisting of a steam-gas mixture - have a temperature of approx. 800°C. This steam/gas mixture is used to generate the jet stream by leading the gas to the two jet nozzles, placed at both sides of the Jetpack evo NT.

Physics: Providing high pressure to the nozzles, the nozzles choke and a supersonic jet is formed that dramatically accelerates the gas converting the thermal energy into kinetic energy. The exhaust speed varies, depending on the expansion ratio the nozzle is designed for. The nozzles of the Jetpack evo NT will accelerate the propulsion steam/gas mixture up to 1688 m/s - which is 5.6 times the speed of sound. Speeds above MACH 5 are not longer called supersonic - the Jetpack evo NT has a hypersonic exhaust velocity.

At the time the gas expands adiabatically, pressure against the nozzles forces the Jetpack in one direction, while accelerating the gas into the other direction. In case of the Jetpack evo NT the engine is based on a rocket propulsion system and a rocket exhaust compared to other engines is generally very noisy. As the hypersonic exhaust mixes with the ambient air, shock waves are formed and the Jetpack evo NT generates a noise level of over 153 dB (A) around its base.

In comparisson, an Eurofigther has a noise level of 121 dB (A) at take-off and the lift-off of a Space Shuttle will be around 200 dB (A).
