Aircraft store ejector system

摘要

An aircraft store ejector systems and subsystems thereof. Embodiments can include a two-reservoir re-pressurization system wherein a remote reservoir is used to maintain desired pressure in a local ejector reservoir. The system can include a release valve having a vent valve and valve piston. The release valve can control release of pressurized gas to a pitch control valve. The pitch control valve can be configured to distribute the pressurized gas between two or more ejector piston assemblies. One or more of the ejector piston assemblies can include multiple concentric piston stages and piston chambers, the piston chambers configured to contain a volume of gas. The ejector piston assemblies can be configured to compress the volume of gas within the piston chambers as the piston stages are extended out from the aircraft. Such compression can provide a return force to the piston stages.

主权项

1. A pressurized gas system for an aircraft store ejector system, comprising:
an aircraft store ejector piston configured to eject an aircraft store from an aircraft; a remote gas reservoir configured to hold a remote volume of a pressurized gas; an ejector gas reservoir fluidly connected to the aircraft store ejector piston and configured to hold an ejector volume of a pressurized gas, wherein the remote volume is greater than the ejector volume and wherein the remote gas reservoir is arranged to supply pressurized gas to the ejector gas reservoir; a pressure regulation arrangement comprising a pressure intensifier interposed between the remote gas reservoir and the ejector gas reservoir, wherein the pressure regulation arrangement pressure intensifier is configured to regulate a pressure of the pressurized gas supplied to the ejector gas reservoir to a desired pressure from an initial pressure lower than the desired pressure; and a relief valve configured to selectively release pressurized gas from the ejector gas reservoir, the relief valve configured to direct released pressurized gas from the ejector reservoir to the pressure regulation arrangement.
