Abstract: An orthogonal power unit includes blade sections with pressure sensitive elements on either side of a foil contour, such as at the widest point. Vents are positioned rearward of the pressure sensitive elements. A controller, such as a linkage or electronic controller, senses a pressure differential between the pressure sensitive elements. When the pressure differential exceeds a threshold, a valve coupled to the vent on the low-pressure side is opened to release pressurized fluid from that vent. The fluid may be combustible gas and an ignitor may be incorporated into the turbine blade to ignite the gas. A channel may pass through the blade sections and a back-pressure valve in each valve section couples the channel to a cavity from which fluid is released through the vents.
