An engine technology that could usher in a new era in the aviation world is being worked on: Ram-Rotor Detonation Motoru (RRDE). This innovative concept promises to deliver higher power and efficiency at hypersonic speeds. However, this design has an obstacle to overcome; It needs to be built strong enough to withstand its own strength.

The second act in the evolution of RDE engines

For the first time in 2020 Rotating Detonation Engine (RDE), the new jet engine, called the rotating detonation engine or rotary detonation engine, had been tested. These engines are built on a completely different principle than traditional combustion engines. Instead of combustion, as their name suggests, they utilize a process in which shock waves break apart fuel molecules, causing explosions. The energy of the explosions is directed in a loop within the engine, providing a constant energy source.

RDEs theoretically offer up to 25 percent higher efficiency compared to conventional engines. However, these engines operate with low efficiency at atmospheric pressure and exhibit their best performance at supersonic and hypersonic speeds.

Dr. from Tsinghua University. Haocheng Wen and Prof. Ram-Rotor Detonation Engine (developed under the leadership of Bing Wang)RRDE), of the RDE engines we mentioned aims to expand its borders. Essentially, this is a rotating detonation engine in which the detonation wave is stabilized in a high-speed rotor. A precisely shaped flow channel inside the rotor, whatever the suction speed It compresses the air-fuel mixture into ideal conditions for explosion. The explosion wave is kept stably inside the rotor.

RRDE achieves higher thermodynamic efficiency by exploiting the extreme pressures and temperatures of the explosion in a way that no conventional ramjet engine can. This new engine concept both at low speeds and hypersonic speeds has the potential to deliver higher efficiency. Theoretically Mach 5+ This engine, which can reach speeds of (6,174 km/h), not only increases efficiency but can also significantly reduce fuel consumption. However, it is currently unclear whether this design can produce the power to take off a plane on its own. What is certain is that it can make the necessary bursts at much slower speeds than classic RDEs.

In addition, RRDE is a design that has successfully proven itself only in theoretical and simulation tests for now. There are also significant engineering challenges to implement the technology. Rotor blades, for example, need to be strong enough to withstand both hypersonic air currents and sustained explosions, yet lightweight. Despite this, rapid advances in hypersonic research, especially in China, raise hopes that this engine can be tested in a short time.
