COMPOSITE WING STRUCTURE AND METHODS OF MANUFACTURE
A pre-cured laminate having a total number of plies formed in a mold. The mold has a cavity having a periphery defined by a forward edge, an aft edge, and outboard ends. The laminate comprises a first plurality of resin impregnated plies that continuously extend beyond the periphery of the mold. The first plurality of resin impregnated plies comprises at least 50 percent of the total number of plies. The laminate has a second plurality of plies that do not extend beyond the forward edge and continuously extend beyond the aft edge of the cavity; a third plurality of plies that do not extend beyond the aft edge and continuously extend beyond the forward edge of the cavity; and a fourth plurality of plies that do not extend beyond the outboard ends and continuously extend beyond the forward and aft edges of the cavity.

An air vehicle, as well as a method for folding an air vehicle for storage, may include a fuselage and a wing connected to the fuselage. The wing may include two ends positioned opposite from each other, and the wing may be substantially perpendicular to the fuselage. At least one of the ends may define a space therebetween the fuselage and the wing. The space may be sized to receive a potion of the wing when the wing is wrapped around the fuselage.
An airfoil member includes a skin member defining an airfoil surface. The airfoil surface has a leading edge surface, an upper airfoil surface, and a lower airfoil surface. An abrasion resistant layer partially covers the skin member. A cermet coating exterior to the skin member covers the abrasion resistant layer. The cermet coating is configured to protect the airfoil member against erosion during operation. The cermet coating includes a ceramic material, and a metallic material. The cermet coating extends chordwise on the upper and lower airfoil surfaces beyond the abrasion resistant layer such that the cermet coating is also applied directly to the skin member.
A method for braking an electric utility vehicle including a motor and an electromechanical brake. The method includes storing a value indicative of at least one of an amount of current, voltage, and power that is commanded to a motor of the electric utility vehicle to maintain the electric utility vehicle in a stopped state; engaging a parking brake function of an electromechanical brake after the storing; disabling the motor after the engaging; commanding the at least one of the current, voltage, and power to the motor at the stored value when an accelerator pedal is depressed; and disengaging the parking brake function after the commanding.

A drive system for an electric vehicle includes a motor for providing a drive torque and an electrically actuated brake for providing a braking torque to the motor. The system includes a controller that receives a plurality of inputs which may include a battery voltage input, a throttle pedal position input, a brake pedal position input, a key switch input, a forward/neutral/reverse (FNR) input, and a brake full-stroke input in addition to the brake pedal input. The controller may generate a drive signal for the motor based on some or all of the inputs.
