Abstract: In exemplary embodiments of this invention, a programmable surface comprises an array of cells. Each of the cells can communicate electronically with adjacent cells in the array, can compute, and can generate either normal thrust or shear thrust. Distributed computing is employed. The programmable surface may cover all or part of the exterior of a craft, such as an aircraft or marine vessel. Or, instead, the programmable surface may comprise the craft itself, which may, for example, take the form of a “flying carpet” or “flying sphere”. The thrust generated by the programmable surface can be employed directly to provide lift. Or it can be used to control the orientation of the craft, by varying the relative amount of thrust outputted by the respective cells. The number of cells employed may be changed on a mission-by-mission basis, to achieve “span on demand”. Each cell may carry its own payload.

Abstract: A compound aircraft features variable incidence wings, a thruster, a rotor and a clutch connecting the engines to the rotor. Upon reaching a suitable forward speed, the control system of the compound aircraft unloads the rotor and disengages the clutch, disconnecting the rotor from the engines. The control system configures the cyclic and collective pitch effectors to cause the rotor to autorotate. The control system selects an autorotation rotational speed that is adequately rapid to prevent excessive deformation of the rotor blades due to aerodynamic forces acting on the blade and that is adequately slow to prevent excessive compressibility effects.
