Description

This is an amendment to the synopsis/solicitation entitled Advanced Laser Ignition Technology which was posted on July 5, 2001. The purpose of this amendment is to answer questions received. Please note-the TBDs are areas that should be answered by the offerors in their proposal. Question 1: Can we get a copy of the existing contract H32231D? Answer 1: See amendment posted on July 5, 2001. Question 2: What item/steps remains to be completed of the existing contract H32231D? Answer 2: A. Design and fabrication of a small workhorse chamber for testing the laser ignition system. B. Test the laser ignition system with RP-1/GO2 under the ambient conditions and then under a rocket thruster chamber environment. Question 3: Is the system defined already or can we evaluate any changes to the design? Answer 3: If the system is referring to the laser ignition system, then the laser ignition has not been defined yet. The goal is to develop the laser ignition system for rocket engine applications. It is also suitable for multi-combustor engines, such as Rocket-Based Combined Cycle (RBCC), etc. Question 4: Are trade studies and calculation available for review? Answer 4: No. Question 5: What are the room dimensions of Test Cell 108? Are drawings available? What utilities are available? Answer 5: Test cell 108 consists of a steel-reinforced concrete enclosure (~15' x 15') with one side open to atmosphere, but with a roll-up door. Adjacent to the test cell back wall, which has two viewports, is an air-conditioned test control room (~15' x 15') with standard power utilities available. General floor plan drawings exist. Question 6: What does the injector look like; possible vendor, p/n, etc. Answer 6: TBD, a simple RP-1/GO2 injector with low flowrates and an O/F ratio of 2.6 will be needed for short duration ignition tests at 200 psia chamber pressure. Question 7: Has any software or hardware been purchased yet? If so, what is the type and capability? Answer 7: No. Labview capability is desired. Question 8: Is there any special security clearances required for the employees to perform this work? Answer 8: No security clearances, but US citizenship is required. Question 9: Is there any schedule, which show the number of tests over time for effort? Answer 9: Testing is to be completed by December 30, 2001 and the number of tests planned is approximately 40. Question 10: What type of laser source technology is desired: diode, solid-state, etc.? Answer 10: Undefined, this is to be defined by the proposal. Question 11: If solid-state; linear flash lamp/pump chamber system or laser diode pumped system? Answer 11: See answer 10. Question 12: What laser power level is desired? Power density? Answer 12: See answer 10. Desire is for ignition of combustor only. Question 13: What laser spot size is desired? Focused or collimated? If focused, what is the focal length? Answer 13: TBD. Question 14: What are the actual engine operating environments? Answer 14: Mixture ratio O/F of 2.6, chamber pressure 200 psia, flowrates ranging from 0.02 to 0.20 lbm/sec, approximately. Question 15: Does the optical window have to provide a hermetic seal or seal against high pressure? Answer 15: Must seal against a chamber pressure of up to 200 psia. Question 16: How is it linked to the ignition system? Answer 16: TBD. Desired to ultimately use fiber optics. Question 17: Are built-in test (BIT) and other diagnostics required? Answer 17: Yes, TBD. Camera diagnostics are required to capture ignition. Question 18: Is there a list of data channels needed for the test? Answer 18: TBD. Typical temperature, pressure, flowrates, power supply, etc. Question 19: What capabilities are desired for the data acquisition system (DAS)? Number of channels? Sampling rate? Answer 19: TBD. See answer 18. Question 20: Does MSFC have a schematic or drawings on the pluming system? How it works, etc.? What all does MSFC supply in the form of hardware? Answer 20: No. Facility has not been built. MSFC will provide propellants, some tubing, valves, and some sensors. Question 21: What spare part level is needed to support the laser equipment and DAS? Answer 21: Undefined. Question 22: Can we get an extension on the response date? Answer 22: Yes, see the response date. Question 23: Item 4 -- "The opportunity window of hot-fire demonstrations at MSFC TS115 will be from August to November 2000." Should this be 2001? Answer 23: It has been changed to November/December 2001. Question 24: Item 5 -- Are drawings available for control interfaces? Answer 24: Control interfaces are the interfaces between the workhorse chamber and laser ignition operations. Contractor shall be responsible for designing the interface, such as propellant activation times, ignition time, etc. MSFC will supply the contractor information needed to complete the control interface designs. Offerors are responsible for monitoring this site for the release of any amendments. Potential offerors are responsible for downloading their own copy of amendments (if any).
