Abstract
Apparatus and method for recovering and arresting an aircraft on a floating platform is disclosed. The aircraft has a fuselage, a wing, and a source of propulsion for propelling the aircraft in flight. During landing approach, an inflatable cushion attached to the fuselage is deployed below the fuselage via inflation. In the inflated condition, a fastening material disposed on a downward facing surface of the cushion is thereby adapted to adhesively contact the floating platform deck so that the forward motion of the aircraft is slowed and arrested. In the preferred embodiment, the fastening material is one of male or female VELCRO.RTM. which is adapted to mate with corresponding VELCRO.RTM. material covering the platform deck.
Claims17
A floating platform based recovery system method for landing an aircraft on a floating platform deck on a body of water, said aircraft including a fuselage having a source of propulsion for propelling the aircraft in a horizontal flight mode and in a short field take-off and landing (STOL) flight mode, a free wing connected to the fuselage for free pivotal movement relative thereto about a spanwise axis, a tail boom connected to the fuselage, said tail boom being formed with at least one of horizontal tail surfaces and vertical tail surfaces to provide for directional stability and/or yaw control, a mechanism for pivoting the fuselage relative to the tail boom about an axis of pivot extending parallel to or coincident with the spanwise axis, and an inflatable cushion attached to at least one of the fuselage or tail boom and having a fastening material disposed on a surface thereof, comprising the steps of:
- (a) establishing a descent flight path of said aircraft toward said floating platform deck;
- (b) pivoting said fuselage relative to said tail boom so that the thrust axis of said source of propulsion moves away from a horizontal plane of reference (x-axis) in the direction of a vertical plane of reference of reference (z-axis) to decrease incident air speed;
- (c) inflating said inflatable cushion prior to touchdown;
- and
- (d) landing said aircraft by contacting said deck with the fastening material on said inflatable cushion so that the forward motion of the aircraft is slowed and arrested.
A floating platform based recovery system method for landing an aircraft on a floating platform deck on a body of water, said aircraft including a fuselage, a wing having an aerodynamic center and connected to said fuselage for free pivotal movement about a spanwise axis for flight in a predetermined generally horizontal direction in a free wing mode of aircraft operation, a propulsion system carried by said fuselage for developing thrust and propelling the aircraft, said propulsion system propelling said aircraft both in said predetermined direction and in a near vertical flight orientation, and aerodynamic surfaces carried by said fuselage for vectoring the thrust of said propulsion system away from the predetermined direction of flight sufficiently to achieve said near vertical flight orientation, thereby establishing a angle between the fuselage and the direction of flight, and an inflatable cushion attached to said fuselage and having a fastening material disposed on the surface thereof, comprising the steps of:
- (a) establishing a descent flight path of said aircraft toward said floating platform deck;
- (b) manipulating said fuselage so that the thrust of said propulsion system moves away from a horizontal plane of reference (x-axis) in the direction of a vertical plane of reference (z-axis) to decrease incident air speed;
- (c) inflating said inflatable cushion prior to touchdown;
- and
- (d) landing said aircraft by contacting said deck with the fastening material on said inflatable cushion so that the forward motion of the aircraft is slowed and arrested.
A thrust vectoring free wing aircraft comprising:
- (a) a fuselage;
- (b) a wing having an aerodynamic center and connected to said fuselage for free pivotal movement about a spanwise axis for flight in a predetermined generally horizontal direction in a free wing mode of operation;
- (c) a propulsion system carried by said fuselage for developing thrust and propelling the aircraft, said propulsion system propelling said aircraft both in said predetermined direction and in a near vertical flight orientation;
- (d) aerodynamic surfaces carried by said fuselage for vectoring the thrust of said propulsion system away from the predetermined direction of flight sufficiently to achieve said near vertical flight orientation, thereby establishing an angle between the fuselage and the direction of flight;
- and
- (e) an inflatable cushion mounted to the fuselage and having a fastening material disposed on a downward facing surface thereof when said inflatable cushion is in inflated condition.
A thrust vectoring free wing aircraft comprising:
- (a) a fuselage having a source of propulsion for propelling the aircraft in a horizontal flight mode and in a short field take-off and landing (STOL) flight mode;
- (b) a free wing connected to the fuselage for free pivotal movement relative thereto about a spanwise axis;
- (c) a tail boom connected to the fuselage, said tail boom being formed with at least one of horizontal tail surfaces and vertical tail surfaces to provide for directional stability and/or yaw control;
- (d) a mechanism for pivoting the fuselage relative to the tail boom about an axis of pivot extending parallel to or coincident with the spanwise axis;
- and
- (e) an inflatable cushion attached to at least of the fuselage and tail boom and having a fastening material disposed on a downwardly facing surface thereof when said inflatable cushion is in inflated condition.
An aircraft, comprising:
- (a) a wing;
- (b) a fuselage;
- (c) a source of propulsion for propelling said aircraft in flight;
- and
- (d) an inflatable cushion mounted to the fuselage and having a fastening material disposed on a downward facing surface thereof when said inflatable cushion is in inflated condition;
- wherein said fastening material is formed from at least one of resiliently deformable hook members and loop members adapted to adhesively attach to the other of resiliently deformable hook members and loop members covering a landing area.
