초록

Accelerations due to excitation of the natural modes of an aircraft\s body are suppressed by an active suppression system. Dedicated accelerometers are positioned in the aircraft at optimal locations for sensing modal induced lateral accelerations. The accelerometer produced signals are processed through control logic which, in response thereto, and in response to aircraft velocity and altitude related signals produces output control signals. The control signals effect rudder deployment creating forces to suppress the natural mode induced accelerations.

청구항

An aircraft modal suppression control system for suppressing aircraft body deflections due to natural body flexure modes, the modal suppression system comprising: control surface means controllably deploying responsive to input control signals; sensor means including one sensor predeterminedly located on the aircraft body to produce an excitation signal representative of excitation of the body in at least two natural modes; velocity means for producing a velocity signal representative of aircraft velocity; and control logic means for producing predetermi...
