Portable aircraft arresting apparatus
First Claim
1. Portable aircraft arresting apparatus comprising, portable platform means having opposite ends, means including energy absorber means on said platform means for said apparatus to be operable in a cable-type aircraft arresting system, means including said energy absorber means and stanchion mast means on said platform means for said apparatus to be operable in a net-type aircraft arresting system, frame means mounted on said platform means and supporting said stanchion mast means for pivotal displacement about a horizontal axis transverse to said opposite end and between horizontal and inclined positions relative to said platform means, said frame means having selectable first and second mounting positions relative to said platform means, said mast means in said first position of said frame means and in said horizontal position of said mast means being in a storage position between said opposite ends of said platform means, said mast means in said first and second positions of said frame means and in said inclined position of said mast means being inclined in opposite directions relative to said platform means, and hydraulic piston and cylinder means between said mast means and said frame means for pivoting said mast means about said axis between said horizontal and inclined positions, said mast means having outer and inner ends, and said axis being between said outer and inner ends and adjacent said inner end.

Abstract
Portable aircraft arresting apparatus is comprised of a towable wheeled trailer providing a platform adapted to be anchored along a runway or landing strip and which carries component parts to selectively provide a cable-type or net-type aircraft arresting system. In connection with a net-type system, the platform includes a stanchion assembly including a stanchion mast. The mast is stored in a horizontal position relative to the platform and is elevated to an inclined position to support a net together with a like platform positioned on the opposite side of the landing strip. To accommodate selectivity and rapid conversion between cable and net-type systems, the platform on opposite sides of the landing strip are reversely oriented, and the stanchion assembly on one of the platforms is detached and reversely mounted on the platform for the inclined stanchion masts on opposite sides of the landing strip to be parallel to one another and inclined in the direction of landing.

- 10. Portable aircraft arresting apparatus comprising, transportable platform means having opposite ends, means including energy absorber means on said platform means for said apparatus to be operable in a cable-type aircraft arresting system, means including said energy absorber means and a stanchion assembly on said platform means for said apparatus to be operable in a net-type aircraft arresting system, said stanchion assembly including frame means having opposite ends and selectively mountable on said platform means for said opposite ends of said frame means to be reversely oriented, a stanchion mast extending in the direction between said opposite ends of said frame means and having inner and outer ends, means supporting said inner end of said stanchion mast on said frame means for pivotal displacement of said mast about an axis transverse to said direction between said opposite ends of said frame means, fluid operated piston and cylinder means having opposite ends connected one to said mast and the other to said frame means and being operable to pivot said mast about said axis between horizontal and inclined positions relative to said platform means, the end of said piston and cylinder means connected to said mast being connected thereto between said axis and said inner end of said mast, said axis being closer to one end of said frame means than the other end end thereof and the end of said piston and cylinder means connected to said frame means being connected to said other end of said frame means, stop means on said mast and said frame means interengaging to locate said mast in said inclined position, and means to brace said mast in said inclined position against displacement relative to said frame means and platform means, said mast in one of said orientations of said frame means and in said horizontal position of said mast being disposed in a storage position between said opposite ends of said platform means.
