US 5,310,135 A · Helicopter integrated fire and flight control having coordinated area bombing control

Abstract

During operation of a flight control system in a coordinated area bombing mode, one pair in a group of pairs of fire control azimuth coordinate error signal and elevation coordinate error signals are faded-in as the aircraft yaw attitude reference and pitch attitude reference, respectively. Each pair is respectively indicative of the change in aircraft yaw attitude and pitch attitude for an aircraft reference axis to be aligned with an aiming line of sight. The aiming line of sight corresponds to a target location within a selected target area. A firing signal is provided in response to both the azimuth and elevation coordinate error signals being below respective threshold magnitudes, and the next pair in the group of pairs of azimuth and elevation coordinate error signals provide the aircraft attitude reference. A selected weapon is fired in response to the firing signal.

Dependent claims

An aircraft flight control system for providing control surface command signals to the aircraft control surfaces thereby controlling the yaw, pitch, roll and lift attitude axes of the aircraft in flight, comprising:

fire control means for providing at least one pair of azimuth and elevation coordinate error signals, said pairs of azimuth and elevation coordinate error signals each being indicative of the change in aircraft yaw attitude and pitch attitude for an aircraft to be aligned with an aiming attitude;
means for providing a coordinated area bombing signal in response to activation of a flight control system coordinated area bombing mode;
and
one of said pairs of azimuth and elevation coordinate error signals providing the aircraft yaw attitude reference and pitch attitude reference in response to said coordinated area bombing signal.
