Abstract: An elbow for use in a cabin air supply system for an aircraft has an inlet duct. The inlet duct diverges into two outlet ducts with an interface area between the outlet ducts. Each of the outlet ducts has a nominal wall thickness, with a central portion of the interface having a first thickness at a point of maximum thickness, and the nominal wall thickness being of a second thickness. The central portion of the interface curves to the central portion of the interface area. A ratio of the first thickness to the second thickness is between 3 and 8. A cabin air supply system is also disclosed.

Abstract: A bracket has an axial rear wall to be secured to a housing for a ram air fan and a base floor defined between lateral sidewalls. The base floor has a slot extending for an axial length and for a lateral width, with a ratio of the length to the width being between 1.24 and 1.29. A ran air fan, a system and a method are also disclosed.
