The specific heat capacity at constant volume (Cv) for an ideal gas is a thermodynamic property that measures the amount of heat energy required to raise the temperature of a given amount of gas while keeping the volume constant. It is a fundamental parameter in thermodynamics and is typically expressed in units of joules per […]

The specific heat capacity at constant pressure, often denoted as Cp, is a thermodynamic property that measures the amount of heat energy required to raise the temperature of a substance while keeping the pressure constant. It quantifies how a substance’s temperature changes when heat is added at a constant pressure. The formula for specific heat

The effective exhaust velocity (Ve) for a rocket engine is a crucial parameter that characterizes the engine’s performance. It represents the speed at which the exhaust gases exit the rocket nozzle. Ve is typically expressed in units of meters per second (m/s) or feet per second (ft/s). The effective exhaust velocity can be calculated using

In a scramjet engine, the term “pressure thrust” refers to the component of thrust generated by the pressure differential between the combustion chamber and the exhaust nozzle. It represents the forward force produced by the difference in pressure between the combustion chamber and the nozzle exit. Pressure thrust is a significant contributor to the engine’s

The momentum thrust of a scramjet engine, like in other types of air-breathing engines, is the component of thrust generated by the change in momentum of the exhaust gases as they are expelled from the engine’s nozzle. It represents the forward force produced by the high-velocity exhaust gases. The formula for calculating the momentum thrust

Unlike a turbojet engine, ramjets and scramjets have no moving parts, only an inlet, a combustor that consists of a fuel injector and a flame holder, and a nozzle. How do ramjets and scramjets work? When mounted on a high speed aircraft, large amounts of surrounding air are continuously brought into the engine inlet because of the forward

The term “pressure thrust” refers to the component of thrust generated by the pressure differential across the nozzle of a propulsion system, such as a ramjet engine. It is a result of the higher pressure at the nozzle exit compared to the lower ambient pressure at the engine’s inlet. Pressure thrust is a significant factor

The momentum thrust of a ramjet engine is the component of the engine’s thrust generated by the change in momentum of the exhaust gases as they are expelled from the engine’s nozzle. It represents the forward force produced by the high-velocity exhaust gases. The formula for calculating the momentum thrust of a ramjet engine is

A ramjet engine provides a simple, light propulsion system for high speed flight. Unlike a turbojet engine, ramjets and scramjets have no moving parts, only an inlet, a combustor that consists of a fuel injector and a flame holder, and a nozzle. When mounted on a high speed aircraft, large amounts of surrounding air are continuously brought into the engine inlet because of the
