- Description
- The Rotor Test Apparatus (RTA) is a wind tunnel test stand designed for testing moderate sized helicopter and tilt-rotors up to approximately 22,000 lb. thrust and 3000HP in the National Full-Scale Aerodynamics Complex (NFAC) at the Ames Research Center. The RTA was originally designed and fabricated by Sikorsky Aircraft and has been in service since 1974.Originally operated by NASA, the RTA is now under U.S. Air Force responsibility as part of the NFAC. It has since been modified by the addition of an on-board force and moment rotor balance system and an (optional) speed increaser transmission (IGB). The current upper rotor shaft and IGB configuration limits the full RTA torque and thrust capability. The RTA structure, rotor balance system and main transmission internal components have no such limitation and can operate at the full rig capability. This modification was designed and developed by DEI (now Allied Aerospace Industries, Inc.).This necessitated extensive changes to the fairing, plumbing, and instrumentation systems. An updated NASA- designed rotor electrical control console was also incorporated, and many other changes have been made by test personnel on the spot as the various test needs dictated over the years. Documentation of some of these test needs changes may be limited. As Phase I of the refurbishment effort, Allied Aerospace was tasked to investigate and scope the work. The results were presented for NASA consideration in 2001.At the time, budget constraints precluded further efforts in defining and proceeding with the work. The tasks detailed herein are considered Phase II of the refurbishment effort based primarily on the aforementioned results, expanded and more work added as now deemed necessary. This effort addresses the design changes, instrumentation and mechanical system modifications, and documentation required for the refurbishment of the RTA. Limited calibrations and functional tests shall be performed to validate the modifications made. The refurbished test stand, spare parts, and associated drawings, data and test and progress reports shall be delivered to the Government along with findings made as a result of the required inspections. These findings may lead to an increase in the work effort. The proposal due date shall be 30 calendar days after issuance of the solicitation. The estimated solicitation release date is 23 Jul 07.
