Abstract: Fatigue, the phenomenon of structural or system failure, caused by repeated excitations from high frequency noise or vibration levels, can occur without warning in inlet cowls, fan ducts and thrust reverser translating cowls of aero engines. In modern day nacelle and fan duct design, the use composite structures predominates and a composite structural component is provided which does not suffer or does not suffer the same extent from such potential fatigue problems. The structural component has a front face for exposure to fatigue generating energy and includes a composite frontal region which includes the front face and which comprises a matrix and a high fatigue-strength metal or metal alloy mesh embodied within the matrix or partially embodied within it at the front face. The matrix is in sheet form and comprises or includes a synthetic resin.

Abstract: A pump system includes a displacement pump whose oscillating fluid pressure variations are connected to drive a membrane pump. The membrane pump in turn oscillates fluid in a fluid-filled vertical pipe connected to a fluid-filled commuting pipe. The displacement of fluid in the commuting pipe induces intake of a fluid to be pumped into the commuting pipe during an intake portion of the oscillation and also induces expulsion of the fluid to be pumped during the remaining portion of the oscillation. The commuting pipe is made long enough so that fluid drawn in during the intake portion does not pass into the vertical pipe but stays in the commuting pipe. A heat exchanger about the vertical pipe dissipates heat that may be passed to the fluid therein by conduction or convection.

The clamps include a lower bracket bent into a resilient arch. The clamps snap into place about the periphery of the light table such that the arch-like lower bracket cooperates with the peripheral frame channel.

Abstract: A wave rotor system includes a wave rotor coupled to first and second end plates. Special ports are provided, one in each of the first and second end plates, to cancel expansion waves generated by the release of working fluid from the wave rotor. One of the expansion waves is reflected in the wave rotor from a reflecting portion, and provided to the special port in the second end plate. Fluid present at the special port in the second end plate has a stagnation pressure and mass flow which is substantially the same as that of the cells of the wave rotor communicating with such special port. This allows for cancellation of the expansion wave generated by the release of working fluid from the wave rotor. The special port in the second end plate has a first end corresponding substantially to the head of the expansion wave, and a second end corresponding substantially to the tail of the expansion wave.
