A modified design concept, utilizing deck motion prediction, for the A-7E automatic carrier landing system.
modifieddesignco00judd.pdf (3.535Mb)Abstract
The present concept of automatic carrier landings, Mode I
operational capability, as employed in Navy carrier-based aircraft,
was investigated. The aircraft chosen for study was the A-7E. The
A-7E All Weather Carrier Landing System (AWCLS) and the carrier
landing environment including burble effects and deck motion were
simulated. Height of hook above ramp, touchdown point, and velocity
of impact dispersions were determined. The current system was
then modified, utilizing the concept of a SPN-42 Deck Motion Compensation
Lead Computer which operates on the basis of known aircraft
characteristics and predicted carrier heave motion. Simulation
showed that automatic carrier landing performance as measured by
number of ramp strikes, hard landings, and bolters could be improved,
The modifications suggested require only a minimum of component
additions to the AWCLS currently in use in the Navy.
