摘要： Passive removal of suction air for producing a laminar flow, and associated systems and methods are disclosed. One such method includes forming a laminar flow region over an external surface of an aircraft by drawing air through the external surface and into a plenum. The method can further include passively directing the air from the plenum overboard the aircraft. For example, the air can be passively directed to a region external to the aircraft having a static pressure lower than a static pressure in the plenum, as a result of the motion of the aircraft. Flows from different sections of the external surface can be combined in a common plenum, and the corresponding massflow rates can be controlled by the local porosity of the external surface.

摘要： Passive removal of suction air for producing a laminar flow, and associated systems and methods are disclosed. One such method includes forming a laminar flow region over an external surface (143) of an aircraft (105) by drawing air through the external surface and into a plenum (142). The method can further include passively directing the air from the plenum overboard the aircraft. For example, the air can be passively directed to a region external to the aircraft having a static pressure lower than a static pressure in the plenum, as a result of the motion of the aircraft. Flows from different sections of the external surface can be combined in a common plenum, and the corresponding massflow rates can be controlled by the local porosity of the external surface.

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： Ram air inlets for use with aircraft environmental control systems and other aircraft and non-aircraft systems are described herein. In one embodiment, a ram air inlet (201) configured in accordance with the present invention includes an inlet lip (308) spaced apart from an inlet housing (310). An inlet door (210) is moveably attached to the inlet housing, and includes a first surface portion (312), a second surface portion (314), and a transition region (313) extending between the first and second surface portions. The first surface portion is moveably positioned at least approximately forward of the inlet lip. The second surface portion is fixed at an angle relative to the first surface portion, and is moveably positioned at least approximately aft of the inlet lip. The transition region is positioned at least approximately adjacent to the inlet lip to form an inlet opening therebetween. Movement of the inlet door in a first direction (351) reduces the size of the inlet opening to thereby decrease the flow of ram air through the inlet. Conversely, movement of the inlet door in a second direction (352) enlarges the inlet opening to increase the flow of ram air through the inlet.
摘要翻译：本文描述了用于飞机环境控制系统和其他飞机和非飞机系统的Ram空气入口。在一个实施例中，根据本发明构造的冲压空气入口（201）包括与入口壳体（310）间隔开的入口唇缘（308）。入口门（210）可移动地连接到入口壳体，并且包括第一表面部分（312），第二表面部分（314）和在第一和第二表面部分之间延伸的过渡区域（313）。第一表面部分可移动地至少位于入口唇缘的前方。第二表面部分相对于第一表面部分以一定角度固定，并且可移动地定位在入口唇缘的至少近似后方。过渡区至少与入口唇缘相邻，以形成入口之间的入口。入口门沿第一方向（351）的移动减小了入口的尺寸，从而减小了冲压空气通过入口的流动。相反，入口门在第二方向（352）上的移动扩大了入口开口，以增加冲压空气通过入口的流动。

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.

摘要翻译：一种与高速移动平台（例如商用或军用飞机）一起使用的串联入口装置。串联入口设备包括皮托特入口，用于将空气供给到在移动平台上承载的空调包的客舱空气压缩机（CAC）。冲洗式热交换器入口设置在皮托特入口的前方并与皮托特入口纵向对准，以将冷却空气供应到空调包装的热交换器。通过将热交换器入口向前和纵向设置为与皮托特入口一致，热交换器入口能够有效地吞下边界层的大部分，这导致在皮托特入口的入口面处更薄的边界层。这使得能够使用较小的喉部区域Pitot入口，以及与皮托特入口一起使用的更短的分流器高度，同时仍然使用皮托特入口实现改进的恢复因子（RF）性能。减小的皮托托入口也可以减少拖曳。
