Arrestment system
First Claim
1. Apparatus for arrestment on a vessel of an aircraft in flight having a parafoil connected to it by shroud lines from the body of the aircraft, comprising:
- support means formed to be uprightly mounted on the vessel;
engaging means pivotally connected to said support means and radially extending therefrom for pivoting downwardly and about said support means upon capturing the shroud lines; and
adjustable braking means operatively connected between said support means and said engaging means for providing a constant force for stopping the aircraft within a predetermined sector of pivoting of said engaging means about said support means.

Abstract
Apparatus and method for recovering and arresting an aircraft or other vele. A boom is swivelly connected to a support structure via braking mechanism. The boom is pivotally connected to the brake mechanism such that it can also pivot in a second, different plane intersecting the plane of rotation of the brake mechanism. A shear pin prevents pivoting of the boom in the second plane until the boom has experienced a predetermined load in that plane. The distal end of the boom distant from the brake mechanism is provided with structure for engaging the aircraft. When the aircraft is flown at and captured by the boom, the weight and motion of the aircraft breaks the shear pin, causing the boom to move in the second plane until engaged by a stop. This rapid change in position of the engaging end of the boom in the second plane prevents the aircraft from pendulating about the boom. Forward motion of the aircraft also causes movement within the brake mechanism in the first plane which absorbs the kinetic energy of the aircraft as the boom swivels against the brake mechanism, so that the aircraft is slowed and arrested.
