Abstract:
1. A mount bracket for use in a cabin air supply system for an aircraft comprising: three first axial end 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 second axial end legs at an opposed second axial end, with one of said first axial end legs being a central leg, and a remaining two of said first axial end legs being positioned at each of two lateral sides of said central leg with one on each of said first and second ends, said first and said second axial end 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 to said feet on said 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; a fillet radius merging said second axial end legs at said second axial end into a flat at said foot, and said bolt hole in said second axial end legs at said second axial end having a diameter, and a ratio of said fillet radius at said feet at said second axial end to said bolt hole diameter is between 0.49 and 0.74; a fillet radius merges one of said first axial end legs at said lateral sides, into a flat at said foot, and a ratio of said fillet radius of said feet at said lateral sides of said first axial end to a diameter of said bolt holes in said legs at said lateral side of said first axial end is between 1.05 and 1.4; and said central leg has a bolt access cutout cut into a face of said central leg, and at a radius, and surrounding said bolt hole associated with said central leg, and a ratio of said radius of said bolt access cutout to a diameter of said bolt hole in said central leg being between 1.76 and 2.22.
