System for onboard lift analysis and apparatus therefor
First Claim
1. A system for evaluating lift development of lift surfaces of an aircraft, the system comprising the steps of:
- measuring an actual pressure being exerted on at least one lift surface,obtaining actual aircraft speed,transmitting said actual pressure measurement and said actual speed to a computer, said computer having a database containing optimal pressure measurements for various speeds,comparing said actual pressure measurement for said actual speed with an optimal pressure measurement for said actual speed to determine whether proper lift is being developed.

Abstract
A method and apparatus for measuring the lift generated by airfoils of an aircraft. This real-time analysis is accomplished by measuring a differential pressure between the upper and lower lift surfaces of the airfoils. The system comprises the steps of: a) measuring an actual differential pressure between the upper and lower lift surfaces for a given aircraft speed, b) transmitting this actual differential pressure measurement to a computer, c) comparing the actual differential pressure measurement with an optimal pressure differential for the same aircraft speed. The apparatus comprises a fixed array of differential pressure sensor mechanisms for measuring actual pressure differentials and a computer for comparing optimal differential pressure measurements to the actual differential pressure measurements. Each sensor mechanism preferably contains a piezoelectric sensor that communicates with the upper and lower lift surfaces.
