What is a retrocket?

RETROOROCKET is a type of rocket engine intended for burn when a ship or object needs to reduce its speed or stop. The term is short for a retrograde missile. Retrorocket placement usually points against the main form of the drive. When it is fired, the retroorocket applies the thrust in the opposite direction of movement, it slows down the vehicle until the speed is affordable or stops. In space and aerial vehicles, including satellites and shuttles, there is an extensive use of retrockets. Once the thrust is applied to the object, it will move in a straight line until other forces are working on it. Theoretically, the satellite, which is launched in one direction, will be infinitely in this direction until it is stopped by another force, such as gravity or physical object.

Most vehicles used in space are designed to accelerate to achieve its goals faster, and this acceleration can slowly continue for a long time depending on the engine type used. You want to slow the vehicleLo down so that it can perform tasks such as a survey or enter orbital around the astronomical body, it is necessary to apply strength in the opposite direction to travel. The solution to this problem is to burn retroocket. The missiles can be designed to shoot in a long, slow burns that gradually slow down the vessel, or can be released in short, intense explosions for quick stopping.

Using specially installed retroetots avoids complex maneuvers with the vehicle. Without the RETROROCKET system, vehicles that need to slow down or stop in space would have to fire another set of engines to turn the vessels and face the opposite direction. As soon as it turns back, then the main power unit would be fired slowly in the opposite direction. The Retrorocket system must be simply released in sufficient quantities to slow down the vessel and no complicated movements are required.

satellites and other vehicles that exist in orbit around Earth useAje retrrocetes to end the orbital period. By firing a retro -cet, the object speed is slowed. As soon as it slows down, it begins to attract to the ground and lose altitude. Gravity and the Earth's atmosphere further slows down the object until they actually enter the atmosphere and fall to the surface. In this way, space questions in 2011 re -entered the Earth's atmosphere, although their descent was always very fixed.
