Abstract: An electric power tethering system for an aircraft having a vertical takeoff and landing flight mode including a takeoff phase and/or a hover phase includes a surface power source and a power tether having a surface end configured to couple to the surface power source and an aircraft end configured to couple to the aircraft. The power tether is configured to transmit power from the surface power source to the aircraft in the takeoff phase and/or the hover phase. The power tether is detachable to decouple the surface power source from the aircraft in response to a power tether release event during flight.

Abstract: A bypass apparatus for lubricant in an unregulated pressurized gearbox including: a block including a lubricant inlet in fluid communication with a pressure relief valve, wherein the pressure relief valve diverts lubricant into the gearbox or into an oil filter, wherein lubricant is returned to the gearbox when the lubricant is cold and/or pressure at the pressure relief valve is high to reduce damage to the gearbox caused by high pressure during a cold start, and when the lubricant temperature increases and the pressure is reduced the pressure relief valve closes and lubricant enters the oil filter.

Abstract: A removable oil filter system includes an oil filter mount, an oil filter element removably connected to the oil filter mount, an impending-bypass indicator connected to the oil filter mount and in fluid communication with an oil in the oil filter system, and a full-bypass indicator in fluid communication with the oil filter mount. The impending-bypass indicator is capable of reporting an impending-bypass condition of the oil filter system. The full-bypass indicator is capable of reporting a full-bypass condition of the oil filter system.
