Three-Way Mount Bracket for Aircraft Cabin Air Supply System

A cabin air supply system for an aircraft comprising:

• an air cycle machine;
• a condenser, and there being two outlet lines from said condenser;
• a pair of cabin air supply compressors being mounted by brackets to a mount bracket, and said mount bracket further mounting a forward manifold, said forward manifold providing a portion of a flow line for each of said outlets of said condenser, and further receiving a portion of a flow line supplying bearing cooling air tapped from a line downstream of said pair of cabin air supply compressors back to bearings of said cabin air supply compressors, and downstream of a heat exchanger;
• and
• said mount bracket including three legs extending from a cylindrical central bore and at a first axial end of said bracket, with an axial direction defined by a central axis of said bore, and two legs at an opposed second axial end, with a central leg on said first axial end, and two of said legs being positioned at each of two lateral sides of said central leg with one on each of said first and second ends, said legs each extending to a foot having a bolt hole, and strengthening legs connecting said feet at each of said lateral sides, and said strengthening legs connecting each of said feet at said lateral sides of said first axial end to a foot on said central leg, and a thickness of said strengthening legs connected said foot on said to central leg is defined as a first dimension, and a distance along said first axial end between a laterally outermost portion of said feet at said each of said lateral sides defined as a second dimension, and a ratio of said first dimension to said second dimension is between 0.032 and 0.037.
