In the context of a turbojet engine, the relationship between the nozzle inlet and exhaust air velocities can be expressed using the continuity equation, which is derived from the conservation of mass. The continuity equation is based on the principle of mass conservation, and Bernoulli’s equation expresses the conservation of energy. The continuity equation is […]

In a cold gas propulsion rocket engine, the term “cold gas” typically refers to the use of compressed gas, often at ambient temperature, as a propellant. This is in contrast to traditional rocket engines where combustion of propellants generates high-temperature exhaust gases. Cold gas propulsion is often used for relatively simple and low-thrust applications, such

In a liquid propellant rocket engine, the throat exhaust air velocity refers to the speed of the exhaust gases at the throat of the rocket nozzle. Liquid propellant rocket engines use liquid oxidizer and fuel, which are mixed and burned in the combustion chamber to produce high-speed exhaust gases. In liquid propellant rocket engines, the

In a solid propellant rocket engine, the throat exhaust air velocity refers to the speed of the exhaust gases at the throat of the rocket nozzle. Solid propellant rocket engines use a preloaded solid propellant that burns from the inside out, producing hot gases. The throat is the narrowest part of the nozzle, and the

The throat exhaust air velocity in a rocket engine refers to the speed of the exhaust gases at the throat of the rocket nozzle. The throat is the narrowest section of the nozzle where the flow reaches its maximum speed. The velocity at the throat is a critical parameter in determining the overall performance of

In a turboshaft engine, the inlet air velocity (V1​) refers to the speed of the incoming air at the entrance of the engine’s inlet. Turboshaft engines are commonly used in helicopters and some other rotorcraft. These engines drive a shaft that is connected to a transmission, which, in turn, powers the rotor system. In turboshaft

In a turboprop engine, the inlet air velocity (V1​) refers to the speed of the incoming air at the entrance of the engine’s inlet. Turboprop engines combine a gas turbine engine with a propeller to generate thrust. Air is drawn into the engine, compressed, mixed with fuel, and then burned to produce high-speed exhaust gases.

The inlet air velocity (V1​) for a turbofan engine refers to the speed of the incoming air at the entrance of the engine’s inlet. In a turbofan engine, air is drawn into the engine and is divided into two streams: one stream passes through the core of the engine (core flow), and the other bypasses

The inlet air velocity for a turbojet engine refers to the speed of the incoming air at the entrance of the engine’s inlet. In a turbojet engine, air is compressed, mixed with fuel, and burned to produce high-speed exhaust gases. The nozzle at the rear of the engine accelerates these gases, creating thrust. The continuity

In the case of cold gas propulsion systems, the cross-sectional area of the exhaust nozzle is crucial for determining the flow characteristics and thrust generation. Cold gas propulsion involves the release of compressed gas (usually stored at high pressure) through a rocket nozzle to produce thrust. For cold gas propulsion, where combustion is not involved,
