    摘要: A manifold assembly (300) configured for integration with a joint cover apparatus in a ducting system to detect leaking gas comprises an elastomeric manifold block (303) having a substantially circular inlet aperture and one or more gas passages (307) (308) fluidly coupled to the inlet aperture. The assembly includes a flow control valve ((309) and (305)) configured to maintain a closed state in which a component (305) of the flow control valve sealedly engages with the inlet aperture (306) to preclude gas at the inlet aperture from flowing into the one or more gas passages until said gas reaches a pressure corresponding to a pressure threshold. The assembly also includes at least one aperture control plate (304) disposed substantially proximate to a lower end of the manifold block and including a substantially circular opening. The aperture control plate (304) is adapted to maintain the substantial circularity of the inlet aperture, so as to ensure a substantially fluid-tight seal.

    摘要: A tandem inlet apparatus (10) for use with a high speed mobile platform, for example a commercial or military aircraft. The tandem inlet apparatus includes a Pitot inlet (102) for feeding air to a cabin air compressor (CAC) of an air conditioning pack carried on the mobile platform. A flush heat exchanger inlet (104) is disposed forwardly of the Pitot inlet and longitudinally aligned with the Pitot inlet, for supplying cooling air to a heat exchanger of the air conditioning pack. By locating the heat exchanger inlet forwardly and longitudinally in line with the Pitot inlet, the heat exchanger inlet is able to effectively swallow a large portion of the boundary layer (118), which results in a thinner boundary layer (122) at the inlet face of the Pitot inlet. This enables a smaller throat area Pitot inlet (113) to be used, as well as a shorter diverter height (108) to be employed with the Pitot inlet, while still realizing an improved recovery factor (RF) performance with the Pitot inlet. The reduced height Pitot inlet also enables drag to be reduced.

    摘要: A system for monitoring pressure change within at least one compartment of an aircraft is provided. The system includes a primary pressure sensor for providing a signal corresponding to a pressure within a primary compartment of the aircraft, a primary monitoring channel coupled to the primary pressure sensor, and an output driver coupled to the primary monitoring channel. The primary monitoring channel includes a band pass filter for receiving and filtering the primary pressure signal, a pressure change circuit for determining a change in the filtered pressure signal and for providing a pressure change output signal corresponding to the change in pressure, and a threshold logic circuit for determining whether the pressure change output signal meets a predetermined threshold and for providing a threshold output signal indicating that a decompression event has occurred if the pressure change output signal meets the predetermined threshold. The output driver receives the primary threshold output signal and outputs a notification signal.

    摘要: Aircraft environmental control systems having a single ram air inlet (201) providing air to both cabin compressors (204a, 204b) and associated heat exchangers are disclosed herein. In one embodiment, and environmental control system for use with an aircraft includes a ram air inlet, an air conditioning pack (206), and an associated heat exchanger (208). In this embodiment, the ram air inlet provides a fist portion of air (212a, 212b) to the air conditioning pack, and a second portion of air to the associated heat exchanger. The first portion of air flows (214a, 214b) from the air conditioning pack and through the heat exchanger before flowing into an aircraft cabin. The second portion of air from the ram air inlet cools the first portion of air in the heat exchanger before exiting the aircraft through a ram air outlet (205). The inlet and outlet can be modulated on an optimized schedule to minimize the net drag of the ram system. A system with two ram air inlets is also disclosed.
