What caractarizes a hydrogen peroxide rocket engine is that it can develop a high power despite being light weighted.
The drawback is that the engine has higher fuel consumption than a combustion engine or a jet engine.
So the rocket engine is best suited for applications where low weight is important and high power is needed for a shorter period of time.
There are military and space applications as well as a few exciting civil applications, like:
* Rotor tip rockets.

Other examples are:
* Rocket cars, rocket gocarts and rocket bikes and
* Personal rocket belts
We are suppliers to several private rocketbelt projects. You can read about it here:Rocketbelts (The link is also on the right side of this page).
An autogyro -also called gyroplane, looks very much like a helicopter, but the rotor is not driven. It rotates freely. Instead the autogyro is driven with the help of a propeller like an airplane.
An autogyro needs to roll faster and faster on the field before the rotor spins fast enough in the wind for the autogyro to lift. 100 meters or so of runway is needed for take-off. Many autogyros have a link shaft from the propeller engine and a cogwheel drive so the rotor can be pre-rotated before take-off. The take-off is than shorter.
If the rotor is pre-rotated with tip rockets it can take-off vertically like a helicopter!
Tip rockets have been tested on very few autogyros.The best known project is Fairey Rotodyne. Fairy Rotodyne could carry about 50 passangers and the first flight took place 1957. Vertical helicopter style take-offs and landings were made, using the tip rockets. Rotodyne was cruising at 310 km/h (!) with help of the thrust from propellers and with the rotor spinning free. Despite the project was a tremendous technical sucess it was still finally cancelled, because the noise was said to be too high when starting and landing in heavily populated city centers. A movie presentation of the Fairey Rotodyne project is found here
I presented the idea to install and test hydrogen peroxide tip rockets on some of the Swedish autogyros, at the Swedish Rotorcraft Flyingclub's annual meeting at Gävle-Sandvikens Airport on May 30 2003. The members found it very interesting. In September 2003 we started the project. The first prototype system was tested on a gyro glider during the summer of 2004. It was a great success! We COULD really make vertical take offs! The development of the system has continued since than. Read about the project here
Propeller with Tip Rockets
My most rescent project is a propeller driven with hydrogen peroxide tip rockets. It is very light and still powerful, if you compare to propellers driven with a conventional gasoline engine.The potential applications are for lifting sailplanes and for very light backpack helicopters.
