Autorotation Aerial Platform Drop

Aerial and sea platforms or personnel for, both, civilian and military application may benefit from a procedure developed in helicopter piloting. Autorotation is the name of the procedure. It is a form of aerial [or fluid] glide.

An object may be dropped from a height at a more controlled and superior glide than from a parachute or drag chute.

The glide mechanism is a fan - the most stable and mechanically safest is a turbofan. That is a fan with cowling surrounding the fan blade outermost tips. If the blade vectored to resist air flow, rather than to streamline through the air with least resistance angles, the fall of the turbofan can be slowed significantly, under the influence of a weighty load.

For further safety, the turbofans must be constructed with fixed fan air intake grills and air exhaust grills.

The mechanism, with duplicate, redundancy could replace

• The parachutes of the aerospace industry

• Relief supply drops

• Personnel insertion vehicles

• Sea drops of objects and divers (Sea Chute)

• Aeroplane or spaceplane, full stall recovery (air to surface glide)
