Abstract
An aircraft ejection system is provided. The aircraft ejection system may comprise a seat, a bridle coupled to the seat, suspension lines coupled to the bridle, and a drogue canopy coupled to the suspension lines. A first side of the drogue canopy may have a lower drag than a second side of the drogue canopy. The first side may comprise a mesh portion and/or an opening to reduce drag. The first side may further include a low-resistance structure with a circular or rectangular geometry. The bridle and the suspension lines may be configured to direct the first side in a predetermined direction, such as downward.
Claims11
An aircraft ejection system, comprising:
- a seat comprising a propulsion system, wherein the propulsion system urges the seat in a first direction;
- and
- a canopy coupled to the seat and comprising a first side having a drag coefficient lower than a second side of the canopy opposite the first side of the canopy, wherein the first side of the canopy comprises a first vent defined by the canopy and devoid of material, and wherein the first vent is oriented away from the first direction and reflects air out the canopy in a second direction different from the first direction, and wherein the orientation of the first vent drives the canopy in the first direction.
An aircraft ejection system, comprising:
- a seat comprising a propulsion system, wherein the propulsion system urges the seat in a first direction;
- a bridle coupled to the seat;
- a suspension line coupled to the bridle;
- and
- a drogue canopy coupled to the suspension line, wherein a first side of the drogue canopy comprises a plurality of vents defined by the drogue canopy and devoid of material, wherein the plurality of vents is oriented opposite the first direction and reflect air out of the drogue canopy in a second direction different from the first direction, and wherein the orientation of the plurality of vents drives the drogue canopy in the first direction.
