US Patent:

43477771, Sep 7, 1982

Filed:

Oct 6, 1980

Appl. No.:

6/194148

Inventors:

Thaddeus Jakubowski - Long Beach CA
Jess W. Lockhart - Torrance CA
Norman F. Robinson - Manhattan Beach CA

Assignee:

McDonnell Douglas Corporation - Long Beach CA

International Classification:

F41F 502

US Classification:

89 15G

Abstract:

A store carrier having automatic sway bracing which includes two sway braces located symmetrically at a span larger than a pair of inner suspension hooks and smaller than a pair of outer suspension hooks. When a store is loaded on either the inner or outer pair of hooks and the hooks close, a pair of spring loaded tapered wedges on each side of vertically moveable sway brace supporting columns are released to slide and wedge against mating tapered surfaces on the sway brace column thereby locking the sway braces against the loaded store. The wedges are compliant in that they are spring biased against the sliding surface so as to avoid unloading the wedge when subjected to vibratory loads. The wedges are thus prevented from excessive tightening when subject to vibration. At hook opening the tapered wedges are driven with the hooks to cocked positions ready to accept the next store.

Appl. No.:

5/672526

Inventors:

Thaddeus Jakubowski - Long Beach CA

Assignee:

McDonnell Douglas Corporation - Long Beach CA

International Classification:

B64D 112

US Classification:

244137R

Abstract:

A store carrier for mounting a jettisonable store on a vehicle such as an aircraft and for releasing the store with ejective force applied at forward and aft locations by thrusters actuated by pressurized medium, the carrier including apparatus for adjustably apportioning the flow of medium to the thrusters by means of a double-acting metering device mounted between the source of medium and the thrusters.

Inventors:

Thaddeus Jakubowski - Mesa AZ

Assignee:

McDonnell Douglas Helicopter Company - Mesa AZ

International Classification:

B64D 104

US Classification:

89 154

Abstract:

There is provided a renewable energy source ejector rack for retaining and releasing stores (bombs or the like) on an aircraft, which has on-board pressurization capability, employs a single pressurization system for two or more release mechanisms, and uses air or other clean non-pyrotechnic pressurized gases both as the energy source and energy transfer medium. The aircraft contains a miniature compressor and purification system. Ambient air is filtered, dried and stored as an energy medium. Since the compressor system is onboard, the pressure can be constantly maintained regardless of temperature change. Using purified air eliminates the excessive cleaning burden imposed when using state-of-the-art pyrotechnics, and eliminates the sealing problems associated with hydraulics.
