Abstract: A locking pin includes a body having a plurality of apertures defined through a sidewall. A closure is disposed at an end of the body. A plurality of latch bolts is disposed in the body and adjacent to the closure. Each latch bolt is moveable through a corresponding one of the apertures and between a locked position, disposed at least partially outside of the body, and an unlocked position, disposed at least substantially within the body. A keeper is coupled to each of the latch bolts and configured to retain the latch bolt in the latched position and to bias the latch bolt for movement from the locked position to the unlocked position. A mechanism selectably engages each latch bolt to move the latch bolt to the locked position, and selectably disengages from the latch bolt to allow the keeper to move the latch bolt to the unlocked position.

Abstract: The invention relates to methods of measuring an aircraft under simulated flight-loads while the aircraft is not in-flight. While the aircraft is under the simulated flight-loads, positions of one or more portions of the aircraft may be measured in order to determine how the aircraft is performing under such loads. The aircraft may be readjusted and/or redesigned based on the measurements in order to reduce drag on the aircraft.
