A -- JET PLUME FLOW SOLUTION SOL 3-102158 DUE 092198 POC Heidi D. Shaw, Contract Specialist, Phone (216) 433-5346, Fax (216) 433-2480, Email Heidi.D.Shaw@lerc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/LeRC/date.html#3-102158. E-MAIL: Heidi D. Shaw, Heidi.D.Shaw@lerc.nasa.gov. This is an amendment to Request for Quotation 3-102158 issued on August 6, 1998. The purpose of this amendment is to respond to questions that have been received. Please note: the closing date for the request for quotation has NOT been extended, and remains at close of business SEPTEMBER 21, 1998. Question 1: "The effort involved in generating grid for a 3d geometry is clearly a function of the complexity of the geometry but this information is not provided. In this case, how does the government expect a potential bidder to cost the effort? Can you provide some guidelines? Is the nozzle geometry actually 3d or is it basically an acsixymmetric configuration made 3d due to the presence of control devices?" Answer 1: The 3D geometry will be an axisymmetric separate flow nozzle made 3D by the addition of noise control devices. Spacial periodicity may be assumed to some degree. Proposals should be based on up to six (6) periods. Question 2: "On which (what type) of computer a one-day solution is expected?" Answer 2: The computer choice is left up to the bidder. This effort is designed to provide a solution that can be used in a design iteration loop. With this in mind, the smaller the computer the better. All computers in the desktop class are equivalently ideal. Posted 08/12/98 (D-SN235938). (0224)
