470 kg (1,030 lb) [ 4] Merlin is a family of rocket engines developed by SpaceX. They are currently a part of the Falcon 9 and Falcon Heavy launch vehicles, and were formerly used on the Falcon 1. Merlin engines use RP-1 and liquid oxygen as rocket propellants in a gas-generator power cycle. The Merlin engine was originally designed for sea ...
The most ubiquitous vacuum-powered accessory is the booster for the power brake system. The vacuum is only an assist and the brakes can still function, requiring greater force, if the booster vacuum is used up. Many older vehicles used vacuum-powered windshield wipers. Loss of manifold vacuum when the engine was working hard, or at wide open ...
242 seconds (2.37 km/s) Burn time. 123 s. Propellant. PBAN - APCP. The Space Shuttle Solid Rocket Booster ( SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. [ 1] A pair of these provided 85% of the Space Shuttle 's thrust at liftoff and for the first two minutes of ascent.
SpaceX has privately funded the development of orbital launch systems that can be reused many times, similar to the reusability of aircraft. SpaceX has developed technologies over the last decade to facilitate full and rapid reuse of space launch vehicles. The project's long-term objectives include returning a launch vehicle first stage to the ...
A vacuum servo is a component used on motor vehicles in their braking system, to provide assistance to the driver by decreasing the braking effort. In the US it is commonly called a brake booster . A vacuum servo, also known as a power booster or power brake unit, uses a vacuum, usually supplied by the engine, to multiply the driver's pedal ...
SpaceX Starship. A Starship prototype in launch configuration: Starship spacecraft S24 stacked on Super Heavy B7. Starship is a two-stage fully reusable super heavy-lift launch vehicle under development by SpaceX. As of July 2024, it is the most massive and powerful vehicle ever to fly. [ 4] SpaceX has developed Starship with the intention of ...
Starship is a spacecraft and second stage [ 3] under development by American aerospace company SpaceX. Stacked atop its booster, the Super Heavy, the pair compose SpaceX's new super heavy-lift space vehicle, also called Starship. The spacecraft is designed to transport both crew and cargo to a variety of destinations, including Earth orbit, the ...
Boeing Starliner. The Boeing Starliner (or CST-100[ b]) is a class of partially reusable spacecraft designed to transport crew to and from the International Space Station (ISS) and other low-Earth-orbit destinations. [ 7][ 8][ 9] It is manufactured by Boeing, with the Commercial Crew Program (CCP) of NASA as the lead customer. [ 10]
