Specific impulse and effective exhaust velocity are dependent on the nozzle design unlike the characteristic velocity, explaining why C-star is an important value when comparing different propulsion system efficiencies. c* can be useful when comparing actual combustion performance to theoretical performance in order to determine how completely ...
A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder . The inception of gunpowder rockets in warfare can be credited to the ancient Chinese, and in the 13th century, the Mongols played a pivotal role in ...
P80 is a solid-fuel first-stage rocket motor used on the European Space Agency Vega rocket (in the P80FW version). It was the world's largest and most powerful one-piece solid-fuel rocket engine, being replaced by the larger P120C on 13 July 2022.
In a dual-thrust solid propellant rocket engine, the propellant mass is composed of two different types (densities) of fuel. In the case of a tandem dual-thrust motor, the fuel nearest to the rocket nozzle burns fast, and the fuel further into the motor's body burns slower. This gives the rocket higher thrust initially, accelerating it rapidly ...
The P120C is a solid-fuel rocket motor designed for use as the first stage of the Vega-C and as the boosters of the Ariane 6 launch vehicles. The solid rocket motors were developed by Europropulsion, a joint venture of Avio and ArianeGroup, for the European Space Agency. The "C" in the name signifies its "Common" use across these vehicles.
A solid rocket booster (SRB) is a solid propellant motor used to provide thrust in spacecraft launches from initial launch through the first ascent. Many launch vehicles, including the Atlas V , [ 1 ] SLS and Space Shuttle , have used SRBs to give launch vehicles much of the thrust required to place the vehicle into orbit.
In the 1960s, the 260 was initially designed to test the feasibility of solid rocket motors for space exploration, including use on the lower stage of the Saturn V. Development of the motors was originally given as parallel contracts to Aerojet and Thiokol. Aerojet won out in the end when Thiokol's test chamber burst at 56% of proving pressure ...
The rapid technological advances of the U.S. rocket industry during World War II, accomplished primarily through the wartime Office of Scientific Research and Development (OSRD) and its cadre of leading scientists, produced a substantial foundation of technical reports and data on solid rockets, propellants, and ballistics.
