Abstract

The shuttle for launching an RPV is connected to a launching tube by a motion and high speed-multiplying pulley and cable assembly. The telescopic launching tube assembly is connected between and parallel to a pair of elongated arms of a sealed U-shaped tubular assembly connected by a manifold to which the telescopic tube and shuttle are latched back against the force of compressed air stored in the U-shaped receiver. The release of the latch is damped to minimize acceleration forces on the launched RPV. The receiver and launching tubes are mounted on an elongated base whose rear end is rotatably connected to an anchor plate and the front end of the tubular assembly is adjustably mounted upon the front of the base on an adjustable jack support.

Claims

1. A launching apparatus for a flying device comprising a sealed elongated U-shaped tubular assembly having a pair of elongated substantially parallel arms joined to each other at one end by a short manifold, a telescopic tube assembly having a closed launching tube at its front end and an open rear end, the open rear end of the telescopic tube assembly being connected to the center of the manifold between the elongated arms whereby the telescopic tube assembly is disposed substantially equidistantly between and parallel to the arms, a source of compressed air connected to the tubular assembly whereby it and the telescopic tube assembly are constituted as a receiver of pressurized fluid for extending the telescopic tube assembly, latching means holding the telescopic tube assembly retracted adjacent the manifold against the force of the pressurized fluid in the receiver, a shuttle connected to be propelled following the launching tube, bracket means on the shuttle for mounting the flying device on the shuttle, latch release means connected to the latching means for releasing the launching tube for movement followed in a launching stroke in response to the expansion of the pressurized fluid whereby the flying device is rapidly propelled toward and past the front end of the apparatus to launch the flying device into the air, the receiver being sufficiently large to provide a full launching stroke of the telescopic tube assembly when the pressurized fluid is allowed to expand, the latch release means being actuated after the receiver is charged with the pressurized fluid for initiating the launching stroke of the telescopic tube assembly, upper and lower rails are mounted on inner surfaces of the arms of the U-shaped tubular assembly, the shuttle and the telescopic tube assembly are slidably engaged with the upper and lower rails, control means is provided for actuating the latch release means, motion-damping means is disposed in the path of movement of the control means, whereby the acceleration of the launching tube is retarded, the U-shaped tubular assembly is mounted on a base frame, an anchor plate, and the rear of the base frame is rotatably mounted about vertical and horizontal axes on the anchor plate whereby an angular orientation and elevation of the apparatus may be varied.

2. A launching apparatus for a flying device comprising a sealed elongated U-shaped tubular assembly having a pair of elongated substantially parallel arms joined to each other at one end by a short manifold, a telescopic tube assembly having a closed launching tube at its front end and an open rear end, the open rear end of the telescopic tube assembly being connected to the center of the manifold between the elongated arms whereby the telescopic tube assembly is disposed substantially equidistantly between and parallel to the arms, a source of compressed air connected to the tubular assembly whereby it and the telescopic tube assembly are constituted as a receiver of pressurized fluid for extending the telescopic tube assembly, latching means holding the telescopic tube assembly retracted adjacent the manifold against the force of the pressurized fluid in the receiver, a shuttle connected to be propelled following the launching tube, bracket means on the shuttle for mounting the flying device on the shuttle, latch release means connected to the latching means for releasing the launching tube for movement followed in a launching stroke in response to the expansion of the pressurized fluid whereby the flying device is rapidly propelled toward and past the front end of the apparatus to launch the flying device into the air, the receiver being sufficiently large to provide a full launching stroke of the telescopic tube assembly when the pressurized fluid is allowed to expand, the latch release means being acutated after the receiver is charged with the pressurized fluid for initiating the launching stroke of the telescopic tube assembly, upper and lower rails are mounted on inner surfaces of the arms of the U-shaped tubular assembly, the shuttle and the telescopic tube assembly are respectively slidably engaged with the upper and lower rails a motion-multiplying and speed increasing cable and pulley assembly connecting the launching tube to the shuttle whereby the shuttle is moved through a greater distance than the launching tube and at a higher rate of speed to facilitate launching of the flying device, the cable and pulley assembly including a pair of pulleys mounted one each alongside the front end of the launching tube, a centering pulley sheave on the shuttle, and a cable having its end connected to the U-shaped tubular assembly and from there extending around the pulleys at the front end of the launching tube and having its midportion reeved around the centering pulley sheave.

3. An apparatus as set forth in claim 2 wherein the arms are extrusions which incorporate the rails.

4. An apparatus as set forth in claim 3 wherein shock-absorbing means is disposed on the ends of the arms in the path of movement of the shuttle, and the shock-absorbing means being constructed and arranged for terminating the launching movement of the shuttle and launching tube.

5. An apparatus as set forth in claim 2 wherein a ball valve connects the rear end of the telescopic tube assembly to the manifold for optionally sealing the U-shaped tubular assembly from the telescopic tube assembly.

6. A launching apparatus as set forth in claim 2, wherein the centering sheave has a substantially vertical axis of rotation.

7. A launching apparatus as set forth in claim 2, including a base frame, horizontal axis pivot means mounting the manifold end of the U-shaped tubular assembly on the base frame, an anchor plate, and the rear of the base frame is rotatably mounted about a vertical axis to the anchor plate whereby an angular orientation and elevation of the apparatus may be varied.
