An electrically actuated aircraft brake system and method which provides for brake wear measurement, brake running clearance adjustment, ram position-based control and improved construction and operation. Brake wear and running clearance measurement are obtained by analyzing the output of position sensing circuitry. The position sensing circuitry, preferably including a LVDT position sensor, is also used to determine braking load, a brake controller including circuitry for effecting displacement of one or more reciprocating rams to load a brake disk stack by a predetermined amount based on a present displacement value of the position signal obtained from the position sensor. The position sensor preferably includes a LVDT transducer connected between the reciprocating ram and a brake housing, and the motive device preferably includes a servo motor. Also provided is an actuator housing including a guideway for each ram, the guideway and ram having the same polygonal cross-section, whereby the ram nut is guided and restrained from rotation by the guideway as it is translated by a ball screw in threaded engagement with the ram nut for selective movement into and out of forceful engagement with the brake disk stack for applying and releasing braking force on a rotatable wheel. An electric motor is drivingly connected to each ball screw by a first gear integral with the ball screw, a second gear in mesh with the first gear, and a pinion on a rotating drive shaft of the electric motor.

An arrowhead mechanical blade retention system incorporates retention bumps directly on a pair of opposed deployable blades. When closing or opening the mechanical blades in a broadhead, the retention bumps are forced to pass each other prior to the mechanical blades deploying. This necessarily puts tension on each blade, tending to hold them into position without any additional components. With sufficient force, the blades will simultaneously cross from a closed flight position with a pivot point on one side of the broadhead body to an open and deployed position on the other side of the broadhead body. Once the retention bumps pass each other to release the blades, there is a significantly reduced force required to completely deploy the blades.

The invention discloses a soldering lug for welding a power module. The soldering lug comprises a metal net framework, wherein a mesh space of the metal net framework is filled with a braze welding material. A liquid phase line temperature of the metal net framework is much greater than a braze welding temperature, and therefore, in a reflow soldering process, the braze welding material is firstly molten to be a liquid state; the mesh space is filled up with 98%-99% of the molten braze welding material; and the metal net framework provides an attachment boundary for the braze welding material in the liquid state, so that the metal net framework and the brake welding material form a plane-like structure. A chip on the soldering lug is uniform in stress at each area, so that displacement in a tangential direction and a normal direction does not occur easily, the length from each area on the power chip to a radiating path of a bottom plate below the power chip is consistent, and thermal resistance is more uniform accordingly, so that the condition that the temperature of the local area of the power chip is too high can be avoided.
