As Ballute be parachute-like drag parachute systems referred to, which is also the air resistance generation serve, however, especially in the application at low air density and in the supersonic range have advantages. The name is derived as a suitcase word from the English words "balloon" and "parachute" (parachute).

Ballutes consist of a balloon-like central body which is surrounded by an annular tube. The ring ensures a defined separation of the flow and thus ensures a stable flight position. The initial development is usually supported by active inflation using a gas cartridge or a small pyrotechnic propellant. Then appropriately attached air inlets create a slight overpressure inside through ram air in order to prevent collapse due to the surrounding outside air flow.

application

Dropping free-fall bombs with ballutes

Because of their good properties at high speeds, Ballutes are sometimes attached to bombs . They slow down the bombs quickly after they have been dropped and enable the carrier aircraft to escape safely from detonation at high speeds and at low altitudes.

Another field of application is space travel , where they are used to brake missiles, e.g. B. on re-entry into the atmosphere. They were also part of the emergency rescue system in the Gemini program .
