20090212160 | Method for producing lateral ejection apparattii for helicopter or plane - An aircraft fuselage, with a seat chassis mounted on a set of track and guide rails. Any ejection seat chassis with an occupant attached to a guide track is ejectable along a lateral trajectory, perpendicular to the horizontal longitudinal axis of an aircraft fuselage interior, and can be guided out of the field of an imperiled aircraft during ejection by a rocket catapult system. A seat, framework, bed or chassis is enabled to eject laterally from an aircraft fuselage since a conventional hinged door is operational within a greater sliding emergency door panel which pneumatic rockets at the top and bottom of the emergency sliding door transverse the greater emergency sliding door panel including an interior fixed conventional hinge operational door along a set of tracks attached to the frame and outer fuselage of said aircraft, out of the path of the lateral ejection seat chassis or chassis', towards the rear of an aircraft where the sliding greater panel is prevented from recoiling by spring loaded latch catches; and which emergency door can also drop-slide down by pneumatic rocket assist for some aircraft where the weight, time and spatial difference between a drop-down and a slide-back emergency door or exit opening can in many instances is a benefit to use a drop-down emergency door or exit, pneumatically propelled; so that an aircraft has less nascent drag from rocket weight, and can result in a fractionally quicker or faster rate of acceleration and removal of the door, panel or canopy from the lateral ejection pathway when feasible. Wing struts can also be removed from the emergency lateral ejection exit pathway by pneumatic or other explosive charge means. Additional supporting fuselage struts and slender tempered glass panes are constructed into the fuselage for increased rigidity for the enlarged fuselage structure incorporating a same near relative number of aircraft seats for pilots and passengers, equipped with lateral ejection apparattii, and has an improved field of view. Dual airbags for positioning the legs and torso of an occupant for a safe emergency exit lateral ejection are embedded or attached to a structure directly in front of a seat chassis. A second set of pressure sensitive airbags, head, neck, spine and organ concave-convex protector are attached on both sides of a seat chassis. Three compartments for altitude appropriate parachutes and a sensor fuse box for opening said desired chute are located inside an ejection seats rigid framework back section. The invention includes an interior side mounted blast shield which a rocket catapult systems rocket nozzles face, and which rocket or rockets are locked by collar seal(s) to a said blast shields, alloy or metallic, ceramic tile backing. A track support launcher platform, column, columns or center console support the lateral ejection apparattii at a functional and comfortable level and height for the occupant or occupants. Otherwise, the tracks or guide rails can be attached directly on an aircraft fuselage floor frame or attached to a wall frame structure in an aircraft fuselage, and can be constructed within rows with aisles on a chain motor reloading laterally aligned guide track for lateral rotor positioning lateral ejection apparattii. | 08-27-2009 |
20090321570 | SYSTEM, METHOD AND APPARATUS FOR WINDBLAST REDUCTION DURING RELEASE OR EJECTION FROM AIRCRAFT - The invention reduces the impact of flowfield forces on objects launched from high speed aircraft during flight. For example, the invention provides a solution for overcoming ejection windblast injuries to pilots and increases the probability of injury-free or low-injury ejection. The gas flow is used to rapidly create a very short duration protective “bubble” in the incoming air flow ahead of the ejecting pilot. The bubble reduces the local flow velocity and aerodynamic forces on the pilot during the injury-critical time period of ejection. The invention also is suitable for reducing the intensity of flowfield forces that act on released military aircraft ordnance, such as bombs and missiles. | 12-31-2009 |
20100155535 | AIRCRAFT EJECTION SEAT WITH MOVEABLE HEADREST - An ejection seat includes a headrest that, upon initiation of the ejection seat, moves forward to support the pilot's head in a tilted-forward position.

20140042273 | WARPED-FLOOR TOLERANT AIRCRAFT SEAT - A track-mounted aircraft seat has seat track locking pins that are capable of moving independently to remain engaged with the seat track assembly in a warped-floor condition. The seat track locking pins are actuated by means of a pair of torque tubes that rotate independently about a common pilot shaft. A control link, which is operated by the user, acts on a pair of bell cranks each of which acts on one of the torque tubes. The control link is attached to the bell cranks by means of a spherical joint. Because the torque tubes rotate independently and because the spherical joint allows the bell cranks also to move independently, in the event of a warped-floor condition, rotation of one torque tube caused by the skewed seat track will not cause the other torque tube to release its track locking pin. | 02-13-2014 |

20090212160 | Method for producing lateral ejection apparattii for helicopter or plane - An aircraft fuselage, with a seat chassis mounted on a set of track and guide rails. Any ejection seat chassis with an occupant attached to a guide track is ejectable along a lateral trajectory, perpendicular to the horizontal longitudinal axis of an aircraft fuselage interior, and can be guided out of the field of an imperiled aircraft during ejection by a rocket catapult system. A seat, framework, bed or chassis is enabled to eject laterally from an aircraft fuselage since a conventional hinged door is operational within a greater sliding emergency door panel which pneumatic rockets at the top and bottom of the emergency sliding door transverse the greater emergency sliding door panel including an interior fixed conventional hinge operational door along a set of tracks attached to the frame and outer fuselage of said aircraft, out of the path of the lateral ejection seat chassis or chassis', towards the rear of an aircraft where the sliding greater panel is prevented from recoiling by spring loaded latch catches; and which emergency door can also drop-slide down by pneumatic rocket assist for some aircraft where the weight, time and spatial difference between a drop-down and a slide-back emergency door or exit opening can in many instances is a benefit to use a drop-down emergency door or exit, pneumatically propelled; so that an aircraft has less nascent drag from rocket weight, and can result in a fractionally quicker or faster rate of acceleration and removal of the door, panel or canopy from the lateral ejection pathway when feasible. Wing struts can also be removed from the emergency lateral ejection exit pathway by pneumatic or other explosive charge means. Additional supporting fuselage struts and slender tempered glass panes are constructed into the fuselage for increased rigidity for the enlarged fuselage structure incorporating a same near relative number of aircraft seats for pilots and passengers, equipped with lateral ejection apparattii, and has an improved field of view. Dual airbags for positioning the legs and torso of an occupant for a safe emergency exit lateral ejection are embedded or attached to a structure directly in front of a seat chassis. A second set of pressure sensitive airbags, head, neck, spine and organ concave-convex protector are attached on both sides of a seat chassis. Three compartments for altitude appropriate parachutes and a sensor fuse box for opening said desired chute are located inside an ejection seats rigid framework back section. The invention includes an interior side mounted blast shield which a rocket catapult systems rocket nozzles face, and which rocket or rockets are locked by collar seal(s) to a said blast shields, alloy or metallic, ceramic tile backing. A track support launcher platform, column, columns or center console support the lateral ejection apparattii at a functional and comfortable level and height for the occupant or occupants. Otherwise, the tracks or guide rails can be attached directly on an aircraft fuselage floor frame or attached to a wall frame structure in an aircraft fuselage, and can be constructed within rows with aisles on a chain motor reloading laterally aligned guide track for lateral rotor positioning lateral ejection apparattii. | 08-27-2009 |
20090321570 | SYSTEM, METHOD AND APPARATUS FOR WINDBLAST REDUCTION DURING RELEASE OR EJECTION FROM AIRCRAFT - The invention reduces the impact of flowfield forces on objects launched from high speed aircraft during flight. For example, the invention provides a solution for overcoming ejection windblast injuries to pilots and increases the probability of injury-free or low-injury ejection. The gas flow is used to rapidly create a very short duration protective “bubble” in the incoming air flow ahead of the ejecting pilot. The bubble reduces the local flow velocity and aerodynamic forces on the pilot during the injury-critical time period of ejection. The invention also is suitable for reducing the intensity of flowfield forces that act on released military aircraft ordnance, such as bombs and missiles. | 12-31-2009 |
