  Objective:  Develop an innovative in-deck lighting fixture design that can withstand the increased heat loads expected from future aircraft.
  Description:  Visual Landing Aids (VLAs) on air capable ships, aircraft carrier flight decks and Expeditionary Airfield matting are required for night and/or low visibility aircraft operations for general lighting, navigation, flight deck, and special purposes. Future aircraft are expected to have hotter exhaust that could threaten the integrity of these lighting fixtures while recovering or taxiing. The Navy seeks an in-deck/Airfield Flush-Deck lighting fixture that can be subjected to aircraft exhaust nozzle indirect temperatures in the range of 600-700F for long dwell periods as well as near-direct temperatures in the range of 1500-1700F for relatively short durations. Current lighting fixtures have external surface materials such as 4130 steel, aluminum alloy, stainless steel, silicone rubber, a night vision device compatible lighting filter and a glass lens coated with Magnesium Fluoride. The solution proposed will need to be conformal to the skin of the existing ships’ structure and Expeditionary Air Field (EAF) AM2 matting, with a fixture design that is form, fit, function compatible with existing shipboard/airfield lighting configurations and be able to accept source light through fiber optic bundles, night vision device compatible lighting filter, LED, and incandescent lighting sources. The carrier environment is extremely challenging. Existing fixtures are capable of withstanding direct impact of aircraft tailhook and/or the tailhook "dragged" across the fixture during arrestment or bolter. The fixture should experience no more than aesthetic damage and should be fully functional after impact. Accumulated damage over time would be permissible but not be so severe as to cause a service issue. The fixture should be usable for a minimum of a 6-month deployment without parts replacement other than normal maintenance actions.

  PHASE I: Provide a conceptual design and identify key technical issues. Prove the technical feasibility of the concept through by addressing those issues through analysis and/or limited lab demonstrations. Provide top level cost and reliability estimates.
  PHASE II: Develop a prototype based on the design concept from Phase I. Provide a detailed test plan, finalize and conduct a scaled capabilities demonstration of the prototype. Address the potential for shipboard/EAF replacement as well as the ability to meet shipboard/EAF environmental requirements. Hone cost and reliability estimates.

  PHASE III: Design and fabricate full-scale fixture(s). Provisions will be made to facilitate shipboard lighting testing of light fixtures and/or the EAF AM2 matting surface. Subsequent to system refinement and all first articles testing, selected components will be lab tested and shipboard/field demonstrated. PRIVATE SECTOR COMMERCIAL POTENTIAL/

  DUAL-USE APPLICATIONS: This technology could benefit a wide range of applications where ruggedized heat resistant lighting applications are required. FAA (runways), Off Shore platforms, and industrial plants require similar lighting sources. Innovative applications would transfer to many other commercial applications.

Questions and Answers:
Q: (Our company) currently manufactures visual aid land luminaires for military flight deck applications and is requesting information to the following questions.
1. We are requesting the class ship that the VLA's will be applied?
2. Can the information be made available on the model # & manufacturer of the current in use VLA's?
3. What is the current deck material (metal) that the existing VLA's are mounted in under the AM2 matting? -- existing VLA's?
A: 1. LHA/LHD (Amphib) and CVN/CV (Carrier) Classes
2. General Scientific Corporation; LHA/LHD Class Part NSN: 5998-01-464-8929 and CVN/CV Class Part NSN: 5998-01-530-9193
3. Deck material is HY 100 or HSLA 100 for CVN/CV and LHA/LHD Class.
Q: Are there, or will there be a list of lights that have heat issues and the characteristics of those lights?
A: . . . response pending . . .
Q: What are the deck thicknesses and the deck materials where the lights are required to meet the heat specs?
A: . . . response pending . . .
Q: We are having difficulty obtaining information on General Scientific Corporation's 5998-01-464-8929 & 5998-01-530-9193 products. Are there any mil specs or Navy drawings on these products? If so, can the be forwarded to us? We tried going through NSN list and nothing appears to be available.
A: . . . response pending . . .
Q: Can this topic include the associated electronics and light sources?
A: . . . response pending . . .
Q: Does this topic include daytime/sunlight VLA systems?
A: Yes, lighting systems are used during all flight operations.
Q: 1. What shipboard power will be used, or available, to drive the light (i.e. voltage)? 2. Also, how will dimming controls be implemented (i.e. are there separate voltage lines, a separate control line, etc.)
A: . . . response pending . . .
Q: Does "conformal to the skin" mean it has to be flush? Typical runway centerline lighting is 10-12mm above the runway surface.
A: . . . response pending . . .
