I’m contemplating getting aloft using a paramotor. If the main ‘glider’ (sail-type parachute) fails, one is ordinarily equipped with a reserve chute, but this is of little use at operational flying levels of ~200m.
Today’s invention is therefore a paramotor fan which can tilt from a horizontal axis to a vertical one, when the pilot realises that a crash landing is imminent. It would automatically jettison the glider canopy once the decision to use the motor in this way was made.
Although the fan could never support a pilot’s weight on its own, it could, in an emergency, greatly reduce the rate of descent, especially if driven at an almost self-destructive speed in this last-ditch mode.
