How will Detonation Space’s engine technology affect the future?
Before start, listen to Dilya about Detonation Space.
Considering today’s needs, different concepts are considered by academic circles in propulsion technologies. Advances in materials science have made great progress, especially in the space industry. The use of systems operating at high pressure and high temperatures has found a place in every field today.
Detonation engine technology is also one of the most popular propulsion technologies that are of interest to academic circles today. First, experimental studies were carried out on the Pulse Detonation Engine, and then the Rotating Detonation Engine model was proposed. There is even an aircraft that has flown with the Pulse Detonation Engine. The aircraft developed by the Air Force Research Laboratory made its flight in 2008 and is currently exhibited in the National Museum of the US Air Force.
However, Pulse Detonation Engine(PDE) has very different features from Rotating Detonation Engine as its working principle. In addition to its very noisy operation, the thrust level it can reach is low due to the frequency of its loop. The rotating detonation engines have high frequencies in terms of the detonation waves. Therefore, very high thrust values can be easily achieved. Fuel flow is also higher due to the fact that combustion takes place at supersonic speeds.
How can Detonation Space engines be so efficient?
Detonation Space engines are based on rotating detonation combustors. It follows the ZND cycle thermodynamically.
The ZND cycle provides higher work gains compared to the cycle of conventional gas turbines (Brayton Cycle).
The thermodynamic cycle of the Lundet-7 engine is presented in the graphic above. In this cycle, the Lundet-7 combustion chamber is a pressure gain combustor (PGC). Compared to the combustion chamber of conventional gas turbine engines, it reaches higher pressure values. Thanks to Shock Compression, additional work gain is achieved. This gives the Lundet-7 engine a gain of over 20% compared to conventional gas turbine engines, regardless of the fuel and oxidizer used. In addition, the Lundet-7 engine becomes 30% more efficient than conventional gas turbine engines when the aerospike nozzle, for which we have done numerical studies, is added.
How will Detonation Space engines be effective in the future?
Detonation Space engines benefit the aerospace industry in many ways. Today, it is seen that many aviation companies are trying to be faster by making mechanical improvements. Mechanical improvements are of course very important. However, Detonation Space provides increased efficiency by making changes on combustion mechanics, not mechanical improvements. Efficiency levels that cannot be achieved with mechanical improvements are thus achieved in Lundet series engines. The graphic below presents how the Lundet series engines will affect the entire aerospace industry.
