The present disclosure relates to a cabin air compressor bracket for an aircraft environmental control system.
Environmental control systems (ECSs) are utilized on various types of aircraft for several purposes, such as in cooling systems for the aircraft. A cabin air conditioning and temperature control system (CACTCS) is an example of an aircraft ECS that includes air cycle packs supplied with pressurized outside (fresh) air from electric motor-driven cabin air compressors (CACs) which condition fresh air for cabin heating and cooling. The CACTCS provides flow control for modulation of cooling pack air flow, recirculation fans to circulate cabin air, and associated valves and sensors used for system control.
The CACTCS may also include a trim air system to provide individual cabin zone temperature control. This includes trim temperature control valves, trim duct heaters and associated sensors. As one example, a CACTCS may provide control of six baseline passenger zones and a flight deck zone. Additional zones, such as a forward cargo zone, a crew zone and/or an attendant zone may be controlled by other ECSs. Recirculation fans may also be provided for additional air flow to the passenger cabin and to ensure that flow at an air distribution nozzle remains constant.
These and other advantages and features will become more apparent from the following description taken in conjunction with the drawings.
In one embodiment a support bracket includes a base including a first hole and a backplane perpendicular to the base. The support bracket also includes three or more connecting surfaces extending outwardly from a right side of the back plane and a mounting tab extending perpendicularly form an outer surface of the third connecting surface and having a mounting tab hole having a diameter formed therein. The support bracket has height and a ratio of the diameter of the mounting tab hole to the height of the bracket is between 0.0467 and 0.0469 in.
The subject matter which is regarded as the invention is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The foregoing and other features, and advantages of the invention are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
As required for an understanding of this disclosure, detailed embodiments are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
Referring to
With reference now to
The lower support bracket 10 includes a backplane 40 connected to one or more of the connecting surfaces 32, 34, 36. The backplane 40 may define a reference plane in one embodiment. In such a case, the backplane has a left and right side and the one or more connecting surfaces 32, 34, 36 extend outwardly from a right side of the backplane 40. In
In one embodiment, first connecting surface 32 extends away perpendicularly away from the base 30 as indicated by right angle 42 between the two. The second connecting surface 34 forms an obtuse angle 44 relative to the first connecting surface 34. Similarly, the third connecting surface 36 forms an obtuse angle with the second connecting surface 34.
The mounting tab 22 extends perpendicularly away from an outer surface 37 of the third connecting surface 36.
With reference now to
In one embodiment, to provide the correct structural strength to support the cabin air compressor and maintain a weight that is not detrimental to flight, the thickness of the base 30 is 0.350 in + or −0.020 in. In the same vein, in one embodiment, a ratio of the outer diameter 142 and the height 106 is between 0.0467 and 0.0469 in.
While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the invention.
