A radar for an aircraft (1) comprises end-plates (4a, 4b) mounted at the tip's of two pairs of aircraft wings (2a, 2b, 3a, 3b). Each end-plate carries a sideways-looking phased array (6) whose beam is unobstructed by aircraft structure. The array can be made to have a large area, thus producing a narrow beam, steerable over a large solid angle. In one embodiment, the end plates (4a, 4b) incorporate fins (5a, 5b) which replace the aircraft fin to afford lateral stability and control.

An airborne vehicle generally comprises a body, a lifting mechanism for lifting the vehicle, and a steering mechanism operable by a user for steering the vehicle. The lifting mechanism comprises first and second counter-rotating propellers mounted in a front end and a rear end, respectively, of the vehicle body. The lifting mechanism further comprises a front air intake and a rear air intake mounted in proximity to and above the first and second propellers, respectively. The steering mechanism c...

An airborne vehicle provided with a rotor assembly consisting of a hub and a plurality of blades spaced axially of the hub, each blade including an inboard section having a forwardly inclined torque vector and an outboard section having a rearwardly inclined torque vector, the chord of the inner section being greater than that of the outer section.

A vehicle for use in airborne geophysical surveys to convey instrumentation for measuring geophysical variables. A single axis of the freedom gyroscope is affixed to the vehicle and has an aerodynamic control surface attached to its gimbal mount so that the precession of the gyroscope, as a consequence of changing roll attitude, moves the control surface, resulting in a movement of the vehicle sufficient to return it to a predetermined path.

The disclosure relates to a vehicle that is sustained in flight solely by thrust from a jet engine and directionally controlled by shifting the center of gravity of the vehicle relative to the thrust axis of the engine.

An improved airborne dispenser for releasing radar reflective material, pyrotechnic flares and the like includes a core member for storage of the material to be released and a protective casing which is removed in flight to allow for optimum dispersion of the material released.

An airborne toy comprising an inverted substantially dish-shaped body normally containing at least one rolled up toy parachute. A flexible support strand, extending through an axial opening in the body, is centrally connected with a disk underlying the body for normally supporting the toy and maintaining the rolled up parachute within the body recess. Another support strand, radially entrained across the outer surface of the body, connects the toy parachute with the first flexible strand opposit...

An airborne body possessing an over-caliber sized guidance mechanism having control surfaces which are retracted into the structure of the airborne body and arrested therein at their end surfaces through a securing arrangement so as to be released for outward extension into the operative position of the guidance mechanism in dependence upon an acceleration in the firing or launching direction. The airborne body is equipped with a pusher rod or ram which concurrently engages into all control surf...

The present invention relates to construction of aircraft engines and has particular reference to the development of novel airborne vehicles. The invention is aimed at providing novel airborne vehicles capable of long-range nonstop flights with a specified amount of cargo, as well as at solving a complex of problems involved in extending the functional capabilities of the existing airborne vehicles. The airborne vehicle comprises a fuselage 1 carrying a suspension unit 6 held thereto and consist...

An improved airborne hoist for use in lifting a load, particularly by means f a helicopter, comprising a pair of rotatable drums, each drum being rotatable in an opposite direction, a drive unit intergeared through a series of shafts for providing rotation to the drums, a cable holding device, in the configuration of a supplemental drum surrounding each of the first said drums, and each cable holding device provided for rotating simultaneously in unison with the rotation of its respective drum, ...
