WebCharacteristic velocity or , or C-star is a measure of the combustion performance of a rocket engine independent of nozzle performance, and is used to compare different propellants and propulsion systems. c* should not be confused with c, which is the … WebApr 28, 2024 · The exhaust velocity for the RS-25 and RL-10 engines is about 4400 m/s in vacuum, 85% of the theoretical value. Our goal is to figure out how the mass of propellant, the rocket, and the payload are related to the final velocity after the propellant is used up.
Characteristic velocity definition and meaning - Collins Dictionary
WebCharacteristic velocity or c*, or C-star is a measure of the combustion performance of a rocket engine independent of nozzle performance, and is used to compare different … WebMay 13, 2024 · The amount of thrust produced by the rocket depends on the mass flow rate through the engine, the exit velocity of the exhaust, and the pressure at the nozzle exit. All of these variables depend on the design of the nozzle. The smallest cross-sectional area of the nozzle is called the throat of the nozzle. ethernet protocol numbers
Parameters Influencing the Characteristic Exhaust Velocity of a …
WebThe exit velocity is a function of the internal properties of the rocket and the fuel. The combustion properties and geometry of the nozzle determine the exit velocity and the … WebThe exit velocity is a function of the internal properties of the rocket and the fuel. The combustion properties and geometry of the nozzle determine the exit velocity and the exit pressure. How this pressure compares to the atmospheric ambient pressure is what determines if the exhaust is over or under expanded. Web- Performance, in terms of characteristic exhaust velocity efficiency, percent C*, was determined from measurements of chamber pressure, propellant flow rates, and nozzle diameter. Chamber pressure was measured with a strain gage type transducer located 1 inch (2.54 cm) downstream from the injector face. Propellant flow ethernet protocol overhead
