Abstract: A power unit connected to a power distribution bus operates in one of several modes to either store excess electrical energy from the power distribution or supply electrical energy to the power distribution bus to account for a detected demand/need. The power unit includes turbomachinery having components connected via a shaft, a generator connected to convert rotational energy associated with the turbomachinery to electrical energy for distribution on the bus, and a motor connected to convert electrical energy distributed by the bus to motive energy used to accelerate the turbomachinery components. A power controller monitors the voltage on the distribution bus. In response to excess voltage on the distribution bus, the power controller connects the motor to the bus to cause the excess electrical energy to be converted to motive energy that is used to accelerate the turbomachinery.

Abstract: An aircraft is provided that includes one or more engines, an air-driven generator, and a start-circuit for operably connecting an electrical output of the air driven generator for starting one or more of the engines while the aircraft is in flight. Various embodiments also provide apparatus for cross-ship electric starting of multiple engines while the aircraft is in flight or on the ground using: an electrical output of a generator attached to another engine; on-board batteries; an on board auxiliary power unit; or power received from a ground source. A single start-converter is utilized to supply power to AC starter-motors for electric starting of the aircraft's engines. In some embodiments, the engine is soft-started with the air driven generator, by controlling blade pitch in an air driven turbine driving the air driven generator, without the use of the start converter.

Abstract: Ballscrew actuators are well known for use as a primary flight control actuator for operating a flight control surface. The operation of the ballscrew actuator is critical to the success of an aircraft mission; however, when the actuator is subject to ballistic fire, a projectile hit which is not totally destructive can still render the actuator inoperable. Increasing the potential for operability of the ballscrew actuator after a projectile hit which is not totally destructive will increase the number of successful returns from aircraft missions.The ballistic tolerant dual load path ballscrew actuator has a selectively-driven ballnut and a ballscrew drivingly connected to the ballnut. The ballscrew has an outer tubular member with an external helical ball groove providing a primary load path. An inner tubular member fits closely within and is fixed to the outer tubular member to provide a secondary load path upon cracking of the outer tubular member by a projectile passing through the outer tubular member.

Abstract: This invention relates to a new and distinct variety of strawberry plant named ‘FPS-14_540-041’. This new strawberry plant named ‘FPS-14_540-041’ is primarily adapted to the growing conditions of the central coast of California, and is primarily characterized by its red fruit color, medium fruit size, and long conical fruit shape; good fruit flavor, good skin firmness, with seeds typically held even with to slightly above the surface; very smooth fruit surface, even in color, with a slight difference in size between primary and secondary fruit; unique trait of a large first flush, followed by an even larger second flush of fruit in the late season; medium plant size, upright in habit with and medium density; medium to dark green foliage color, and medium foliage size; and fruiting trusses typically held above to level with the plant, with low to medium pubescence.
