Chemical Rockets are limited by the underlying chemical reaction. Chemical bound energy is converted into thermal energy and then into kinetic energy (Figure 1). energy (Figure 1). In the process, the energy is partially radiated (thermal radiation), or unintentionally converted into friction. Also currents occur transverse to the direction of thrust. After deduction of energetic losses, typically 40-70% of the applied (chemically bound energy supplied) is available for the actual thrust of the actual thrust of rocket engines.

Catalysts can exert an influence on chemical processes. In general, the the chemical industry, processes with catalysts are already catalysts in order to increase the economy, energy efficiency and yield per reaction (approx. over 80% of chemical processes with an processes with an increasing tendency). According to current knowledge catalysts mainly reduce the required activation energy by bridging the bonds in the reaction partners. reaction partners. The development and optimization of catalysts is a future field of technology that has not yet been fully exploited.

Claims:
In particular catalysts can be uased to advantage in the newer air-breathing propulsion concepts can be used to advantage - such as in ramjets and scramjets. Short of fuel or air mass flow speak for the use of catalysts. the use of catalysts. The use of catalysts represents possible optimization of oxidizer and fuel burnout (fuel). fuel (propellant).

In conventional rocket engines, the reaction is almost complete due to is almost complete through continuous optimization, but catalysts can also catalysts can also achieve large effects indirectly. These effects can replace thermochemical effects (e.g. explosive reaction). reaction). Further effects result from the equalization of combustion. Thus, the use of catalysts in aerospikes advanced nozzle concepts is advantageous to overcome thermal challenges. challenges. Also the constriction of the neck on conventional bell nozzles could be reduced or optimized. optimized. This would result in energy advantages would result. Due to the reduced temperature, the performance of turbopumps and the turbopumps and the fuel supply can be increased. With temperature, service life and strength are improved. improved.

The concept is referred to as the driver concept, since the chemical reaction of the reaction of the fuel is to be driven. The goal is to effective support of the siphon concept under the changing operating conditions. Even under reduced ambient temperature explosive conversion of e.g. hydrogen and oxygen (oxyhydrogen reaction) can be achieved. (oxyhydrogen reaction) can be achieved. This also applies to methane and oxygen or other reaction partners.
It different homogeneous and heterogeneous catalysts are explicitly discussed. are discussed.
