Optimal nonlinear control of flight faults in manned aircrafts in the presence of fault and failure of control actuato
Control actuators' faults are among the major reasons to lose aircraft control while flights. The plane dynamics is severely dependent upon faults and errors in flight control systems and if the reformed control order is not issued by the fault tolerant controller there would be unpleasant outcomes such as inconsistency and the reduction of system performance and some dreadful aerial accide...
متن کاملPlasma Actuators for Hingeless Aerodynamic Control of an Unmanned Air Vehicle
The use of dielectric barrier discharge plasma actuators for hingeless flow control over a 47-deg 1303 unmanned combat air vehicle wing is described. Control was implemented at the wing leading edge to provide longitudinal control without the use of hinged control surfaces.Wind-tunnel tests were conducted at a chord Reynolds number of 4:12 10 and angles of attack ranging from 15 to 35 deg to ev...
متن کاملChallenges for 100 Milligram Flapping Flight
Creating insect-scale flapping flight at the 0.1 gram size has presented significant engineering challenges. A particular focus has been on creating miniature machines which generate similar wing stroke kinematics as flies or bees. Key challenges have been thorax mechanics, thorax dynamics, and obtaining high powerto-weight ratio actuators. Careful attention to mechanical design of the thorax a...
متن کاملThrust Measurement of Dielectric Barrier Discharge Plasma Actuators and Power Requirements for Aerodynamic Control
Plasma-based aerodynamic actuators can modify a flow field without the need for moving control surfaces or a source of pressurized air. Actuator power consumption and thrust production were measured for driving frequencies between 1 and 18 kHz, and for driving voltages of 6 and 9 kV peak to peak. The actuator consumed between 3 and 22 W, and produced thrust levels between 0.05 and 0.2 mN per me...
متن کاملAirfoil Leading and Trailing Edge Separation Control Using SDBD Plasma Actuators
Wind tunnel experiments were conducted to understand boundary layer separation control on airfoils. The objective of this research was to better implement flow control strategies with single dielectric barrier discharge (SDBD) plasma actuator designs for airfoils that exhibit both leading and trailing edge stall characteristics at realistic flight speeds and Reynolds numbers. The NASA energy ef...
