Patent number: 5667167Abstract: A reusable single-stage-to-orbit spacecraft and a reusable launch assist platform provide a new system for space transportation. The platform has a frame with a cradle for supporting the spacecraft. Rocket engines attached to the launch assist platform propel the launch assist platform and the spacecraft substantially vertically through the atmosphere for release of the spacecraft. The launch assist platform returns to a predetermined landing site in a power-controlled, vertical descent.The spacecraft is in the shape of a cone having a large, rounded base with a primary load-bearing structure substantially perpendicular to the base. The spacecraft reenters the atmosphere in a base-first reentry, and is slowed and guided to a landing site by using a rocket engine in the base. The spacecraft lands base first on a resilient landing device.Type: GrantFiled: September 2, 1994Date of Patent: September 16, 1997Assignee: Kistler Aerospace CorporationInventor: Walter Paul Kistler

Patent number: 5577687Abstract: A portable helicopter landing pad especially suitable for deployment on an unprepared surface comprises a number of perforated metal mats which on being joined at their edges define a heliport of predetermined size and shape. Dual-purpose connectors releasably join adjacent mats to one another and anchor the edges of the mats to the underlying surface. If needed, moveable stiffening plates are provided for strengthening the assembled mats where the wheels or skids of the helicopter touch down. A rigid container is provided for transporting and storing the predetermined number of mats, connectors, and tools needed for a particular heliport. For larger installations, several containers are pre-packed to facilitate the transport and assembly of the required components. The container is designed to prevent the stacked mats, connectors, and tools from shifting while in transit. A removable cover retains the container's contents and further prevents them from slipping during storage and transport.Type: GrantFiled: August 21, 1995Date of Patent: November 26, 1996Inventor: James R.

Patent number: 4700912Abstract: A giant column of air is employed to assist in the vertical take-off and landing of an aircraft. The column of air is forced through movable louvers which steer the aircraft on the air column. A pressure differential occurs on top of the air column so as to center an aircraft on the air column. In order to illuminate the air column, a salt spray is introduced into the column and a laser source resonates the crystals of the salt thereby causing energy to be radiated from the column which may be detected and displayed by an approaching aircraft.Type: GrantFiled: April 24, 1986Date of Patent: October 20, 1987Assignee: Grumman Aerospace CorporationInventor: Marshall J. Corbett

Patent number: 4669683Abstract: A pivotable safety railing for a platform such as a helicopter landing pad is disclosed. The safety railing includes a suitable hand railing of sufficient height to protect a person on the landing pad, and mounted on a pivot shaft extending along an edge of the platform. The pivot shaft allows the railing to pivot downwardly to a horizontal position while a helicopter is landing or taking off, and to pivot upwardly to an upright, or vertical, position, when a helicopter is resting on the landing pad. The pivot shaft is driven by a suitable electric motor which is controlled by sensors located on the landing pad, the sensors causing the pivot shaft to be driven in a direction to move the railing to its horizontal position whenever there is no helicopter present on the pad, and causing the shaft to be driven in a direction to raise the railing to its vertical position whenever a helicopter has landed.Type: GrantFiled: March 3, 1986Date of Patent: June 2, 1987Inventor: Lloyd J.

Patent number: 4462560Abstract: This invention provides a system for launching aircraft into free flight regime regardless of runway conditions, wherein a sled of the self-powered air cushion vehicle type is configured in plan form so as to accept in temporarily locked relation thereupon and in combination therewith an airplane in such manner that a successful take-off run in mutually aerodynamically compatible regime may be accomplished in spite of surface problems with the runway. Upon attainment of airborne speed, under control of the pilot the aircraft lifts off the sled into full free flight; and thus is airborne albeit the runway is at the time unusable by conventional wheel-geared aircraft; for example, as the result of a previous bombing attack on the runway by enemy aircraft. The sled incorporates self-propelling and directional guidance means for retrieval/reuse purposes, as well as a take-off abort control system.Type: GrantFiled: January 26, 1982Date of Patent: July 31, 1984Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: T.

Patent number: 4116408Abstract: A portable heliport adapted to be transported by a helicopter is described. The heliport includes a pair of deck extensions having foldable, extensible legs and which are hinged to a central deck supported by extensible legs. The deck extensions are folded and allowed to unfold by a winch which is detachable from the central deck and whose winch support also supports the deck extensions for transport by the helicopter. The extensible legs have threaded tubes telescoping in fixed tubes and quick releasable internally threaded, split clamps attached to the fixed tubes hold the threaded tubes in adjusted positions. The threaded tubes may be screwed into or out of the split clamps for fine adjustments. The legs on one side of the deck are longer than those on the opposite side so that, when the legs are all in contracted conditions, the port is in a condition adapted to a moderate slope site.Type: GrantFiled: January 14, 1977Date of Patent: September 26, 1978Assignee: Soloy Conversions, Ltd.Inventor: Joe I.
