Abstract

The Modulated Rotor Tip Light (MRTL) system provides greatly enhanced visibility because blade tip light paths appear very large, intensity and narrow field of view LED optics are used and lateral separation between red and green lights can be as much as five times larger than the fuselage width. EMTEQ s state-of-the art, high intensity LED light engines and avionics expertise are used to develop an MRTL system using wireless communication between a rotor shaft sensor, a cockpit Controller and multiple rotor blade tip light assemblies to control multiple tip cap LED s. Rapid switching at appropriate times can meet requirements for position lights such as coverage, light intensity distribution and overlap. We will implement the Navy s vision and demonstrate MRTL feasibility by designing, building, testing and demonstrating functional hardware in Phase I. As a premier aircraft lighting suppler, we have produced and support more than 18,000 aircraft exterior lighting units used on more than 30 aircraft models, both rotary and fixed wing.
