Patent number: 8961634Abstract: A filter system includes a filter assembly having an interior, an end defining a bypass opening, and another end for coupling to an air intake of an aircraft engine to permit intake air from the interior to enter the air intake. The filter system includes a bypass closure movable relative to the filter assembly between at least a first position and a second position. The bypass closure substantially covers the bypass opening in the first position to inhibit intake air from entering the interior through the bypass opening. The filter system includes an actuator coupled to at least one of the filter assembly and the bypass member to cause relative movement of the bypass closure between the first and second positions.Type: GrantFiled: October 17, 2011Date of Patent: February 24, 2015Assignee: Aerospace Filtration Systems, Inc.Inventor: Mark Edward Boyce

Publication number: 20140077039Abstract: An aircraft includes a fuselage and wings mounted on opposite sides of the fuselage for sustained forward flight. An engine is mounted in the fuselage or at least one of the wings and includes an air intake. At least a portion of the air intake generally faces the forward direction for receiving intake air during forward flight. A filter assembly is mounted adjacent the air intake and disposed to impinge air and block objects from passing therethrough. A heated screen includes a heater and is mounted adjacent the air intake and upstream of the engine such that ice entering the air intake contacts the heated screen before entering the engine. A power source is provided to supply power to the heater.Type: ApplicationFiled: December 28, 2012Publication date: March 20, 2014Applicant: Aerospace Filtration Systems, Inc.Inventor: Aerospace Filtration Systems, Inc.

Patent number: 8163050Abstract: An inlet barrier filter system for mounting on an aircraft to filter air prior to intake into an engine of the aircraft includes a frame having at least two curved frame members defining an opening. A filter element has a curved inward face and is received in the opening of the frame. The filter element includes filter media having pleats. A comb is attached to the frame and includes spaced-apart teeth that support the pleats. The comb is curved to generally conform to the curved inward face of the filter.Type: GrantFiled: January 15, 2008Date of Patent: April 24, 2012Assignee: Aerospace Filtration Systems, Inc.Inventor: Robert R.

Patent number: 7634984Abstract: An air induction system for an engine to remove contaminants from intake air prior to delivery to the engine. The system includes an assembly for filtering air which is mounted in advance of the engine, and a duct for delivering air from the assembly to the engine. A sealing system is provided which prevents entry of unfiltered air while simultaneously permitting movement of the engine relative to adjacent parts of the airframe as engine power setting varies. The seal is protected from high pressures in the duct which can occur in operation of the engine.Type: GrantFiled: March 15, 2007Date of Patent: December 22, 2009Assignee: Aerospace Filtration Systems, Inc.Inventors: James F. Stelzer, Thomas L. Newman

Patent number: 7575014Abstract: An air induction system for an engine having an improved mechanism for control of an intake door. The system includes a housing having an opening for receiving intake air. A power activated door is pivotable between a closed position wherein the opening is closed and an open position wherein intake air may enter through the opening. Linkages operatively connect an actuator cylinder to the door. The linkages are configured such that movement of the cylinder produces a corresponding rotation of the door which is non-uniform across the cylinder's range of motion. The linkages include first and second bellcranks mounted for pivotal motion, and a link which interconnects the bellcranks. Movement of the cylinder at a first position causes pivoting of the door, while movement at a second position causes substantially no pivoting of the door.Type: GrantFiled: July 29, 2005Date of Patent: August 18, 2009Assignee: Aerospace Filtration Systems, Inc.Inventor: James F. Stelzer

Patent number: 7491253Abstract: An air induction system for an engine to remove contaminants from intake air prior to delivery to the engine. The system includes a filtering unit having barrier filter panels attachable to a mounting frame. The filter panels are interchangeably usable. A juncture between first and second filter panels and the mounting frame is located at a region of relatively lower quantity of intake air flow. The juncture includes lugs on the filter panels which facilitate interchangeability. An opening above the filtering unit permits easy installation and removal of filter panels.Type: GrantFiled: May 31, 2005Date of Patent: February 17, 2009Assignee: Aerospace Filtrations Systems, Inc.Inventor: Joseph Wilson
