Aircraft glide slope coupler and landing system
专利汇可以提供Aircraft glide slope coupler and landing system专利检索，专利查询，专利分析的服务。并且A glide slope coupler, adapted for use in an integrated automatic pilot and flight director system provides apparatus for guiding an aircraft with respect to a radio defined glide slope to a flare out point, and for providing the flare out command for an automatic landing or for a flight director landing. An integrating device is used for synchronizing the coupler prior to glide slope mode engagement, and operates as a radio error integrator subsequent to autopilot glide slope engagement. The integrator operates to wash out the steady state flight path angle subsequent to flight director glide slope engagement. In the synchronizing mode, the elevator actuator amplifier output is forced to zero by the integrator to assure that no engage transients occur. At the same time, the integrator output is initialized by virtue of the system gain ratios, to a value approximately equal to the desired glide slope flight path angle. After glide slope engagement, the integrator output is summed with signals representing craft displacement from the glide slope, craft flight path angle, and short term damping signals, all for operation of the craft elevator surface or a flight director indicator pitch bar to reduce the radio defined path displacement to zero. As the aircraft descends through approximately 50 feet, radio gains are reduced to zero and the flare computer automatically computes a flare point and issues the proper flare commands for the specific conditions relative to descent rates and winds for each approach. The flare command automatically reduces shortly after touch down to cause the nose wheel to settle firmly on the landing surface. If the craft has a tendency to float due to abnormal conditions, this reduction in flare command will slightly increase the descent rate to assure a touch down within the longitudinal requirements.，下面是Aircraft glide slope coupler and landing system专利的具体信息内容。
