Ballute

Ballute

A ballute (a portmanteau combining "balloon" and "parachute") was invented by Goodyear in 1958. It is a parachute braking device that is optimized for use at high altitudes and high supersonic velocities. The original ballute was a cone-shaped balloon with a toroidal burble fence fitted around its widest point. It is either inflated by a gas generator, or by air forced into the structure by ram air inlets.

Ballutes have also been proposed in toroidal form.

Applications

The ballute has been used as a retarding device for freefall bombs dropped from aircraft. It was used as part of the escape equipment for the Gemini spacecraft. It has been proposed for use during aerocapture and aerobraking.

Fictional references

A ballute is seen in the film 2010. It is used by the spaceship "Alexei Leonov" for an aerobraking manoeuvre around the planet Jupiter to enter orbit about the moon Io.

In the animated Gundam series, ballutes are used for ships or mobile suits to re-enter Earth's atmosphere.
