Do rocket engines have turbos?

On a fire engine you just use an internal combustion engine. But in a rocket engine we use a gas turbine. The resulting steam will then drive the turbine driving the turbo pump. In more advance designs they utilize the main rocket fuel in various ways to drive the turbine.

Are bigger rockets more efficient?

The primary motivation for the development of large capacity launch vehicles seems to be that of efficiency – a bigger vehicle will be more efficient at delivering a given payload to LEO than multiple smaller vehicles.

Where are Raptor engines built?

Since September 2016, the Raptor engine to be used on the Starship spacecraft and Super Heavy booster has undergone test firings at McGregor. The engines, which have been upgraded over time, are currently built at SpaceX’s main factory in Hawthorne, California, then transported to McGregor for testing.

What did the Soviet Union use rockets for?

Soviet rocketry spanned the entire history of the Soviet Union (1922–1991). Rocket scientists and engineers contributed to the development of rocket and jet engine propulsion systems, which were first used for artillery and later for fighter aircraft, bombers, ballistic missiles, and space exploration.

How many engines does a rocket booster have?

An RD-107 rocket engine, at the base of each booster, has four main combustion chambers and two smaller vernier engines. The six combustion chambers share a single set of fuel pumps and are considered to be one engine. The boosters are identified as Blok- B, V, G, and D.

What is the difference between Molniya rocket and Vostok rocket?

The Molniya rocket replaced the Vostok upper stage with the new Blok-I stage. The Blok-I featured four large combustion chambers, and four vernier chambers. The Blok-I, with its more powerful engine and larger fuel tanks, offered significantly better performance then the Blok-E stage from the Vostok rocket.

What is the difference between Blok-I and Vostok rockets?

The Blok-I featured four large combustion chambers, and four vernier chambers. The Blok-I, with its more powerful engine and larger fuel tanks, offered significantly better performance then the Blok-E stage from the Vostok rocket. Molniya rockets include a Blok-L upper-stage on top of the Blok-I.
