Engine inlet duct installation

An inlet duct assembly comprising:

• a first inlet duct leg, the first inlet duct leg including:
• a first mounting flange;
• and
• a fastener extending from the first mounting flange, the fastener having a fastener head disposed at a preselected distance from the mounting flange;
• a second duct leg including:
• a second mounting flange configured to abut the first mounting flange;
• a slidably located mounting strip having:
• a strip opening, the fastener extending therethrough;
• and
• a tightening ramp having an increasing height in one direction;
• wherein sliding the mounting strip along the second mounting flange increases a tension on the fastener and thus secures the first mounting flange to the second mounting flange.

A method of installing an inlet duct assembly to a rotary winged aircraft comprising:

• locating a first inlet duct leg at an engine inlet of a rotary winged aircraft, the first inlet duct leg including:
• a first mounting flange;
• and
• a fastener extending from the first mounting flange, the fastener having a fastener head disposed at a preselected distance from the mounting flange;
• locating a second inlet duct leg at the engine inlet such that a second mounting flange of the second inlet duct leg abuts the first mounting flange, the second inlet duct leg including a slidably located mounting strip having:
• a strip opening, the fastener extending therethrough;
• and
• a tightening ramp having an increasing height in one direction;
• and
• sliding the mounting strip to increase tension on the fastener thereby securing the second mounting flange to the first mounting flange.
