- Description
- NASA/DFRC has a requirement for the Development of Unsteady Aerodynamic Modeling Updating of High Altitude Long Endurance Aircraft (HALE)Project at Dryden Flight Research Center (DFRC) has a need for a Contractor to develop a specific technique to update unsteady aerodynamic modeling of HALE class of vehicles. Development is to be performed of a technique to update unsteady aerodynamic models based on correlation with frequency-domain flight test date (typically control surface oscillation sine-sweep data). One of the most important issues in this effort is likely to be definition of the tuning design variables. While a final selection has not been made, there are two leading candidates in this effort. The first is to define the AIC matrix at a few "hardpoint" frequencies in terms of an analytical AIC matrix and a tuning increment. The individual matrix elements of the tuning increment are then used as design variables. The second method is to define the unsteady aerodynamics in terms of a rational function approximation (RFA), and to define increments to the terms in the RFA as design variables. The software will be implemented first as a prototype in MATLAB or SciPy. This will provide a rapid prototyping environment that will make it very easy to test the formulation for bugs, and ensure that the correct implementation will be coded into FORTRAN. Prototype software and analytically defined test case (Matlab or SciPy code, 4 months after contract award). FORTRAN version of software, demonstrated on analytically defined test case and validated against prototype software. (8 Months after contract award) Software theoretical and user documentation. (9 Months after contract award) NASA/DFRC intends to purchase the items from M4 Engineering, Inc., 2161 Gundry Avenue, Signal Hill, California 90755. M4 Engineering has proprietary rights over the goods and services being procured. Inlight that it is a novel approach to solving the unsteady arrowelastic model updating problem that offers a significantly higher chance of success than other algorithms. The Government intends to acquire a commercial item using FAR Part 12 and 13. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on ____7/29/05_______. Such capabilities/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. An Ombudsman has been appointed.
