Abstract
The instant invention relates to a system for estimating aircraft angle of attack .alpha. and sideslip angle .beta. from measured quantities such as angular body rate and linear acceleration. The estimated angle of attack and sideslip signals are generated by means of a Kalman filter configuration which simulates a model of the aircraft angle of attack and sideslip angle dynamics, and may be used either in an aircraft flight control network or for display purposes.
Claims3
In an estimator network for estimating aircraft parameters, such as angle of attack or sideslip angle from measured aircraft parameters such as pitch, roll, speed, acceleration and gravity forces,
- a. a network including:
- 1. means for producing in response to measured aircraft angular pitch and roll measurements a signal proportional to the rate of change of the aircraft parameter to be estimated,
- 2.
