Web1. Plot the variation of the density specific impulse(product of average specific gravity and specific impulse) with mixture ratio and explain the meaning of the curve. Use the theoretical shifting specific impulse values of Fig. 5–1 and the specific gravities from Fig. 7–1 or Table 7–1 for the liquid oxygen–RP-1 propellant combination. WebJan 3, 2024 · The specific impulse (usually written as Isp, or in-game as ISP) defines the efficiency of an engine. It is thrust per the rate of fuel consumption. Or equivalently, it is change in momentum per amount of fuel consumed.

WebSpecific Impulse definition: A performance measure for rocket propellants that is equal to units of thrust per unit weight of propellant consumed per unit time. WebWhen the prefix specific is used in physics, it means "relative to" a particular quantity. Specific gravity and specific heat are two examples of where you may have seen this prefix used. Specific impulse is impulse measured …

WebSpecific impulse, like you said, is a measurement of a rocket engine's efficiency. It's given in seconds (kind of odd but I'll explain). Let's say an engine generates 10 kilograms of thrust (10 kgf for kilogram-force) and consumes one kilogram of propellant per second (1 kg/sec). Specific impulse (usually abbreviated Isp) is a measure of how efficiently a reaction mass engine (a rocket using propellant or a jet engine using fuel) creates thrust. For engines whose reaction mass is only the fuel they carry, specific impulse is exactly proportional to the effective exhaust gas velocity. A propulsion … See more The amount of propellant can be measured either in units of mass or weight.

It is represented by the symbol J and usually expressed in Newton-seconds …

WebOur definition of impulse includes an assumption that the force is constant over the time interval Δ t. Forces are usually not constant. Forces vary considerably even during the brief time intervals considered. It is, however, possible to find an average effective force Feff that produces the same result as the corresponding time-varying force.
