- Description
- To: See Distribution List From: David Frederick Engineering Branch Landing Gear Division OO-ALC/LILE 6040 Gum Lane Hill AFB, UT 84056-5825 SUBJECT: Market Research Information Request - T-38 Wheel & Brake Upgrade This Market Research Information Request (RFI) is being sent in advance of an anticipated open distribution Request for Proposal (RFP). In developing your response you are reminded that the Government does not intend to award a contract on the basis of this request or otherwise pay for the information solicited. The demand for the T-38 wheel and brake upgrade is driven by the need to improve the reliability, wear life, performance and safety of the existing T-38 brake, also to improve the reliability of the existing wheel and incorporate radial tire technology. The demand for this upgrade will as well support anticipated weapon system gross weight increases. The T-38 fleet is expected to remain in service until the year 2024. There are currently (585) airplanes in active service in the United States (USAF, NASA, and Navy). An estimated 1,521 brakes and 1800 wheels will be required for initial provisioning and spares. Information provided by respondents will help ensure that an RFP is prepared with satisfactory information. Preliminary wheel and brake requirements are provided in this RFI as guidelines. REQUESTED INFORMATION 1) Please provide a description of wheel and brake upgrade concept(s) that would meet the preliminary requirements. The Air Force will consider all proposed concepts prior to establishing the program direction of any future T-38 wheel and brake upgrade program. Please provide concept layout drawings that highlight key features, and include a summary of the impact of the proposed design on related systems (i.e., hydraulics, addition of anti-skid, etc.). 2) A radial tire option will be available for the T-38 in the near future. Please comment on the advantages and disadvantages to qualifying a wheel for use with both tire types? 3) Please provide an estimated dry weight (new and worn) for an upgraded wheel and brake. 4) Please provide the estimated brake wear life and time (cycles) between wheel overhauls. 5) For how many years should a brake be designed to remain on an airplane axle before corrosion, hydraulic leaks, oxidation, etc., become problems? 6) Please provide a top-level program schedule that highlights major program milestones between program launch and flight test equipment delivery. The objective is to provide information that will identify development phases and deliverables, and will provide a general understanding of the amount of time required for development of the equipment. Where necessary please state assumptions. For example, assumed qualification test requirements should be stated in support of a schedule estimate. 7) In terms of production capacity, please identify and discuss what should be assumed as a reasonable amount of time to retrofit the fleet with an upgraded wheel and brake. From a supplier perspective, please identify issues and problems related to a fleet retrofit with the best ways to resolve or mitigate those issues and problems. From a supplier perspective, please provide advantages and disadvantages of a time compliant retrofit in comparison to a retrofit by attrition. 8) Please estimate the following for the T-38 wheel and brake upgrade: - Number of Full Stop Landings to achieve a 100% worn brake- Landings per wheel- Maximum number of wheel overhauls- Years to develop & qualify new wheel and brake- Years to retrofit fleet- Development costs- MLG wheel cost (initial provisioning)- MLG wheel cost (after initial provisioning)- Brake assembly cost (initial provisioning)- Brake assembly cost (after initial provisioning)- Heat sink cost (after initial provisioning)- Man-hours to build up wheel/tire assembly and install wheel and brake - Additional heat sink mass required to complete 100% worn brake RTO at the brake energy, inertia, and decel rate described below. 9) What other critical program issues/problems would you anticipate and what could be done to address them?
