1. IN AN AIRBORNE VEHICLE HAVING AN INTERNAL DUCT SYSTEM RECEIVING AIR THROUGH INTAKE PORTS WITHIN THE EXTERNAL SHELL AT THE FRONT OF THE VEHICLE AND EXHAUSTING AIR AT THE REAR OF THE VEHICLE, A VORTEX VALVE IN SAID DUCT SYSTEM RECEIVING THE AIR AT ITS CIRCUMFERENCE AS IT PASSES FROM FRONT TO REAR OF THE VEHICLE AND EXHAUSTING IT BY RADIAL FLOW AT ITS CENTER, A LINEAR ACCELEROMETER RESPONSIVE TO LONGITUDINAL ACCELERATIONS OF THE VEHICLE PRODUCING A SIGNAL IN ACCORDANCE THEREWITH, AND MEANS CONTROLLING THE VORTEX VALVE FROM SAID SIGNAL TO VARY THE RADIAL FLOW AND THUS RESISTANCE TO FLOW OF THE AIR THROUGH THE VALVE AND THUS INCREASE THE RESISTANCE OF SUCH FLOW, TO COMPENSATE FOR VARIATIONS IN AERODYNAMIC DRAG OF THE VEHICLE WHEREBY IT FOLLOWS A TRAJECTORY INVOLVING SUBSTANTIALLY CONSTANT FORWARD RESISTANCE.
