Description

NASA/DFRC plans to issue a Request for Quotation (RFQ) for an aeronautical engineer (1 ea.) to support the Active Aeroelastic Wing Program. The period of performance will be for one year. The Active Aeroelastic Wing program is a joint program between NASA DFRC and the Air Force Research Lab. The objective is to demonstrate on a full scale aircraft that wing twist can be used for roll control. NASA's need is for an experienced senior engineer to perform the following tasks: Task 1 Active Aeroelastic Wing Consulting. Provide consulting and review of program activities. The tasks would include review of research objectives, flight test approach to achieve those objectives. In addition the engineer would suggest new or changed objectives and could identify better approaches to achieve those objectives. The engineer must have a long association with aeroelastic wing research. Specifically association with wind tunnel research conducted by both NASA and the Air Force is very important. A knowledge of flight control, flight test planning and flight test conduct is also important. The engineer would participate in program technical reviews at DFRC and possibly other locations. The engineer would also review and suggest changes to technical documents including those containing flight test objectives, ground and flight research objectives and flight test plans. Task 2 NASTRAN Aerodynamic Model. The purpose of this research is to develop an aerodynamic idealization of the F-18 AAW aircraft in order to accomplish multiple tasks. The first task is to develop a set of generic guidelines for the development of an aerodynamic idealization, which can be used to develop an aerodynamic model of a new/untested vehicle. The second is to be able to use this idealization to develop an analytically derived loads model and to determine how accurate of an analytical loads model needs to be developed to make use of a concurrent control law and structural design tool such as ISMD. The third task which would result from this research is to analytically predict loads and strains which can be used to investigate a method for improving the accuracy of strain gage calibrations: 1. Create an aerodynamic model, which includes the F-18 wing, significant fuselage influences and control surfaces, within NASTRAN to be used with Flight Loads that will allow analytical loads predictions to be made. Multiple models may need to be made to account for control surface deflections so that an analytically derived loads model can be developed. 2. Validate aerodynamic model with flight determined loads and/or wind tunnel loads and modify the aerodynamic idealization as necessary to match flight loads. 3. Determine, if possible, a methodology for modifying the aerodynamic idealization for a new aircraft configuration. Deliverable Items: Aerodynamic model utilizing the NASTRAN Tools. Written document covering the results of the development, and the results of the work on developing a methodology applicable to a new aircraft configuration. Security: This is a unclassified contract. However the engineer must be a US Citizen and cannot release any data developed in this program to foreign nationals or foreign companies. Location of work: Work will be primarily performed by the engineer at his/her current location. For quotation purposes assume 4 trips to NASA DFRC at Edwards, CA each lasting four days. Also one trip to the Air Force Research Lab at Dayton OH for four days. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA/DFRC intends to obtain the above specialized services from the South West Research Institute (a non-profit organization), The authority for other than full and open competion is 10 U.S.C. 2304(a)(1) "Only one responsible source and no other supplies or services will satisfy agency requirements". Justification is based upon NASA DFRC's requirement for an experienced aeronautical engineer with specialized expert knowledge of the AAW program and familiarity with the current on-going project. Additionally, the engineer must have an extensive background and experience with wind tunnel work at Langley and with the Air Force. NASA DFRC has identified a technical expert at South West Research Institute who has this specialized knowledge and has successfully served as a consultant to the Air Force on AAW program formulation and its overall objectives. Therefore this engineer will be able to immediately provide valuable consulting information without having to learn the program. The Government does not intend to acquire a commercial item using FAR Part 12. Interested organizations may submit their capabilities and qualifications to perform this effort in writing to the identified point of contact not later than 4:30 p.m. local time on or before February 15, 2001. Such capabilities and/or qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice is solely within the discretion of the government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. OMBUDSMAN STATEMENT REQUIRED] An Ombudsman has been appointed. See NASA Specific Note "B". Any referenced notes can be viewed at the following URL: http://genesis.gsfc.nasa.gov/nasanote.html
