Gambit: The engine that will redefine military aviation.
DARPA signed a contract with Raytheon to develop a practical version of the revolutionary air intake rotating detonation engine called Gambit. The peculiarity of this engine is the absence of moving parts, which can lead to the creation of lighter missiles with a long range and reduce their cost.
Gas turbines, despite their efficiency, have a number of disadvantages. They are difficult to manufacture, heavy, and require expensive maintenance and special materials to operate at high temperatures. These disadvantages are particularly relevant for single-use weapons such as cruise missiles.
Alternatively, a Rotating Detonation Engine (RDE) is available. In RDE, a combustible mixture of fuel and air is fed into the gap between two coaxial cylinders. When the mixture is ignited, it burns in the form of a supersonic wave that moves inside the gap, creating thrust. Such engines are simple to design, inexpensive to manufacture, and lightweight.
The main task is to transfer the RDE from the test stage on stands to a working prototype. Under the terms of the contract with DARPA, Raytheon will develop the Gambit engine until a design is obtained that can be adapted for future military weapons systems.
At the moment, the project is at stage 1, which includes preliminary design of the engine and its main components. At the second stage, it is planned to manufacture and test the engine itself.
Colin Whelan, President of Advanced Technology at Raytheon, stated: "This is a revolutionary engine system. We use existing digital design tools and the expertise of the entire RTX business to quickly prototype this next-generation weapon and refine the technology."
