Embodiment 1

[0031] Example 1. A kind of RAT generator bleed air window, constitutes as Figure 1-5 As shown, it includes a support arm hole 2 arranged on the generator support arm 11, and the support arm hole 2 is covered with a trumpet-shaped drainage cover 1; the drainage cover 1 includes U-shaped lips I3 and U-shaped lips II4 arranged oppositely, U-shaped lip Ⅲ5, U-shaped lip Ⅳ6 and hole net 9 arranged oppositely; U-shaped lips Ⅰ~Ⅳ constitute the quadrilateral large-end air inlet of the drainage hood 1, and holes are provided at the small-end air outlet of the drainage hood 1 Net 9, hole net 9 and the support arm 11 taper surface of support arm hole 2 places are bonded. The air is drained through the shroud 1 , passes through the support arm hole 2 and then flows through the RAT generator. After the generator is cooled, it is exhausted through the upper end of the generator.

[0032] The drainage cover 1 is a thin-walled sheet metal part with a thickness of 0.6 mm to 1 mm. The drain...

Abstract

The invention discloses a bleed air window of an RAT generator. Comprising a supporting arm hole (2) formed in a generator supporting arm (11), and the supporting arm hole (2) is covered with a trumpet-shaped drainage cover (1). The drainage cover (1) comprises a U-shaped lip I (3), a U-shaped lip II (4), a U-shaped lip III (5), a U-shaped lip IV (6) and a hole net (9), wherein the U-shaped lip I (3) and the U-shaped lip II (4) are oppositely arranged, and the U-shaped lip III (5) and the U-shaped lip IV (6) are oppositely arranged. The U-shaped lips I-IV form a quadrilateral large-end air inlet of the drainage cover (1), a hole net (9) is arranged at a small-end air outlet of the drainage cover (1), and the hole net (9) is attached to the conical surface of the supporting arm (11) at the supporting arm hole (2). The technical problems that an existing air entraining window is complex in manufacturing process, high in machining cost and large in influence on the weight of an overall mechanism are solved.

Description

technical field [0001] The invention belongs to the technical field of aviation emergency energy, and in particular relates to a bleed air window of a RAT generator. Background technique [0002] The traditional RAT generator bleed window is directly opened and drilled on the support arm, the manufacturing process is complicated, and the processing cost is high (see Image 6 ). In addition, since the generator needs sufficient cooling air, the window size on the support arm is large, which affects the structural strength. In order to make up for the strength of the mechanism, the support arm is designed to be thicker, which wastes more weight. In order to solve the above problems and disadvantages, it is necessary to invent a new RAT generator bleed air window to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a RAT generator bleed air window. The invention solves the technical problems of complex manufactu...
