Ramjet engines

@Ambarveis I misspelled word bo sorry 😓

i was pretty sure this said raptor engine the other day, but yeah ramjets cool

@Ambarveis A ramjet engine is a type of air-breathing jet engine that operates on the principle of the ram effect, which uses the forward motion of the engine through the atmosphere to compress incoming air without the need for compressor blades. Ramjets are primarily designed for supersonic and hypersonic speeds, typically ranging from Mach 2 to Mach 6 (twice to six times the speed of sound).

The key feature of a ramjet engine is its simplicity. It consists of an inlet, a combustion chamber, and a nozzle. Unlike other jet engines, a ramjet does not have any moving parts, such as a compressor or turbine. Instead, it relies on the high-speed air entering the engine to create compression and mixing with fuel for combustion.

Here's how a ramjet engine operates:

1. Inlet: The ramjet engine's forward motion compresses the incoming air before it enters the combustion chamber. This compression is achieved through a carefully designed inlet geometry that slows down and increases the pressure of the incoming air.

2. Combustion: Once the compressed air reaches the combustion chamber, fuel is injected and mixed with the air. The mixture is ignited, creating a continuous combustion process. The combustion produces high-temperature and high-pressure gases.

3. Nozzle: The hot gases expand through a nozzle at the rear of the engine, generating thrust. The nozzle accelerates the exhaust gases to create a high-speed jet of gas, which propels the engine and the vehicle forward.

One significant limitation of ramjet engines is that they cannot produce thrust at low speeds or at rest. They rely on the forward motion of the vehicle to compress the air. Therefore, ramjets are usually combined with other propulsion systems, such as rockets or turbojets, for initial acceleration or takeoff.

Ramjets are commonly used in applications where high speeds are required, such as cruise missiles, unmanned aerial vehicles (UAVs), and certain hypersonic aircraft. They are particularly suitable for sustained high-speed flight, as their simple design allows for lightweight and efficient propulsion systems. However, due to their operational limitations, ramjets are not suitable for subsonic speeds or stationary applications.

well yeah everything's a replica but what do you think raptor engines are

@Ambarveis but those are not ramjet engines

we have Fuel-Flow Staged meth
