- Description
- Questions and Answers received in response to this notice. No further questions will be accepted after 8/10/2011. Q1Concerning Prime Power: Para. No. 3.6. Request clarification on safely removing charge from the batteries and energy storage system. A1.When a 'kill' switch is pressed on the demonstrator, the entire system must quickly go to an inherently 'safe' state. The exact timeline under which this must occur and the exact requirements of that 'safe' state will be clarified further as the program addresses the flight clearance process. Q2.Can you provide specific interface details (SWaP, command and control interfaces) for the following subsystems for which NAVAIR has previously invested (Para no. 2.1) : 1. Beam director/beam control 2. Prime power system 3. Thermal Management system A2.The various sub-systems will meet the specifications described in Table 1. The Government does not intend to provide additional details about the subsystems that NAVAIR has been developing for this program, beyond that indicated in the RFI. Should we choose to issue an RFP or BAA following the RFI, the additional information will be made available at that time. Q3.Concerning para. No. 3.4. The Aircraft (MH-60 S) power only meets Mil-STD-704A. Please verify that the subsystems (designed to MIL-STD-704E) will operate satisfactorily with this aircraft power. Possible issues include power transients. A3.It is a requirement of the prime power subsystem that properly conditioned power can be delivered to all the other subsystems. Q4.Is the RFI looking for white papers describing subsystems, such as the power system or thermal management system, or just for white papers describing the complete system? A4.As described in this RFI, the Government has the subsystems under development already. We are looking for proposals on integration of the subsystems, whether using the NAVAIR developed subsystems or technologies owned/developed by the proposer. Q5.Substantial waste heat will need to be removed and dissipated. What will be the final heat sink for this heat? A rotary winged aircraft may not have the RAM air available with fixed wing aircraft. A5.Final heat sink is the ambient air. Storage of the waste heat on-board is also possible as long as the duty cycle of 30% (laser on time) can be met. Q6.What is the date for the white paper submission? The solicitation indicates xx August 2011. A6.August 22, 2011. Q7. Is spectral beam combining required? A7.Yes Q8. What are the targets? A8. The demonstrator must meet the specifications outlined in Table 1 of the RFI, and the text that follows in Q9. Q9.Is target acquisition to be stand alone or will there be cueing from other sensors such as radars? A9.Stand-alone, man-in-the-loop sufficient for demonstration Q10. It is stated that the coverage is to be 360 degrees under the aircraft. What coverage from directly under the aircraft is required /desired? A10.It is desired to have coverage of the ground/water surface in all directions from the aircraft up to the maximum range of 4 km slant range. Q11.What reports addressing the aero-optics of the aircraft are available? A11.The Government has results of some aero-optic modeling (which will not be made available as part of the RFI process) and will be performing necessary flight tests to further address the issue as part of the program. Q12.What definition of beam quality is to be used? Does the definition apply to each beam/wavelength separately or to total beam on target? A12.The Government is requesting an M2 value of less than 1.5. Since the lasers of interest produce a Gaussian spatial distribution, the M2 value is appropriate to use and is just the ratio of the resultant (total) beam to a diffraction limited beam at the same distance. Or, formally, theta = (M2 * lambda) / (pi * w0); where theta is the half divergence angle of the beam, lambda is the central wavelength and w0 is the beam radius at the beam waist.
