Abstract The deployment of folded down wings in an aircraft following, for example, rocket assisted launching from the container is carried out through gas pressure springs with strong attenuation in the final phase, the springs being releasably coupled to the wings for being jettisoned upon completion of deployment.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
86 words
A vehicle having wing portions affixed to the fuselage and pivotable wing portions hinged to said affixed wing portions, each said portions having bores, a pair of gas pressure springs with final phase attenuation and having end pins stuck into said bores, respectively, for jettisoning the gas pressure spring following spring operated and attenuated deployment; and a jettison assist spring bearing against one of the pins and said gas pressure spring to ensure jettison of the gas pressure spring in the direction away from the fuselage.
