E-MAIL: Carlos D. Torrez, ctorrez@mail.arc.nasa.gov. NASA/ARC plans to issue a Request for Offer (RFO) for ROTOR DYNAMICS ANALYSIS OF LIGHT HELICOPTERS. The requirement is for studies of possible unusual rotor and flight dynamic characteristics of very light, teetering-rotor helicopters in a variety of maneuvers and operating conditions (FRIAR NTSB Study). The objectives of the studies are to determine whether any fundamentally unknown or undiscovered aeromechanics characteristics exist for the light teetering rotor class of helicopter particularly, but not limited to, operation in unusual flight conditions. This will provide a better understanding of the potential hazards for light helicopter operation at unusual flight conditions that may not be clearly recognized at the present time. The approach will be to employ comprehensive analytical computer models, specifically the ART-developed FlightLab and the U.S. Army Aeroflightdynamics Directorate's 2GCHAS program codes to study helicopter dynamic responses to a variety of typical pilot control and atmospheric gust inputs. Delivery is required 12 months after contract award. NASA/ARC intends to purchase the studies from Advanced Rotorcraft Technologies, Inc. (ART), of Mountain View, CA, pursuant to 10 USC 2304(c)(1). ART is considered the only responsible source for this requirement due to its unique combination of experience and technical capability with both codes in the rotorcraft technical community. ART is the developer of the FlightLab Code and has the most extensive experience with the code. ART is also one of the original members of the Government/Contractor team that developed the Army's 2GCHAS code, and they have been continuously involved as a contractor with enhancement and maintenance of the system. See Note 22. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. An Ombudsman has been appointed. See Internet Note "B". Interested firms have 15 days from the publication of this synopsis to submit in writing to the identified point of contact, their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after the 15 days or without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government to not compete this proposed effort on a full and open competitive basis, based upon responses to this notice is solely within the discretion of the Government. Firm date for receipt of offers will be stated in the RFO. All qualified responsible sources may submit an offer which shall be considered by the agency.
