- Description
- The purpose of this amendment is to distribute the Questions and Answers which were discussed at Industry Day held at China Lake, CA on 20 March 2007. Also enclosed as an attachment to this notice is the Attendees Listing. Ultra Endurance UAV Heavy-Fuel Engine Development Industry Day - 20 March 2007 N68936-07-R-0020 - Ultra Endurance Unmanned Aerial Vehicle (UE-UAV) Questions and Answers 1. Q: There seems to be some confusion in the response date for the white paper. It's currently posted as 23 April, but the brief says 16 April. Which is correct? A: The correct date is 16 April. 23 April was a typographical error. See Table 5.1 – Significant Dates and Times, in the original synopsis. This date was also corrected in amendment 1 to the synopsis dated 7 March 2007. 2. Q: Why is the tolerance on AC power set at .75 kw. If we could generate more, would that be acceptable. A: Yes, you can produce more, but the requirement is for .75 kw, while also producing 5 horsepower at the propeller shaft. 3. Q: Also, shouldn't that be a minimum of 9 horse power? You’d accept something higher, right? A: Yes. At full power the engine must produce a minimum of 8.5 (nominal 9 SHP) propeller-shaft horsepower. 4. Q: Are the dwell time figures based on MSL standard? A: There are no dwell time requirements. However, performance parameters will be corrected to Sea Level. 5. Q: I assume the ideal engine would propel the airframe to 15,000 to 16,000 feet altitude. A: The objective is 15,000 feet. 6. Q: What is included in the propulsion system? A: This information is specified in the Broad Agency Announcement (BAA). 7. Q: You're looking for speeds of 2500 to 5000 RPM? A: The BAA suggests an RPM range. We're really looking for a typical RPM range at 5 propeller-shaft horsepower? 8. Q: Why do you specify AC power? A: That's what we felt would be best. But we’re willing to listen if you think DC power would be better. Just be sure to make the point and back it up in your white paper. 9. Q: Will the AC power be conditioned to something else? A: Yes, by the aircraft. 10. Q: The AC power generation components must be included in the total engine weight? A: Yes. 11. Q: Will differences be considered in the white paper. For example, does the engine have to be the weight specified or if a heavier engine is proposed that will fly longer, can that be considered? A: Yes, if it is reasonably similar and the efficiency is increased. 12. Q: The pusher propeller is the most likely? A: Most likely. 13. Q: What is the propeller size and RPM of the existing Aerolight aircraft? A: Two-blade, 22" propeller at 3600-7000 RPM. The propeller can be 2- or 3-blade and the RPM can vary. 14. Q: If we are testing in the 2500 to 5000 RPM range, we may need larger propellers to move air. A: The performance specifications will be validated during ground testing. If a propeller change is required for aircraft integration, this is allowed as long as it provides sufficient thrust for flight. 15. Q: Will airframes be available for form, fit, and function checks? A: Yes, some access will be provided later in the program. 16. Q: What is the current engine in the Aerolight? A: It is the Q100M from Quadra Aerrow. With the generator, it weights 12 lbs. 17. Q: Are these commercially available airframes? A: Yes. These are manufactured by Aeronautics Defense Systems Ltd (Isreali). There is more information available on the web (see URL below). The Association for Unmanned Vehicle Systems International (AUVSI) and Shephard have database information. http://www.aeronautics-sys.com/Index.asp?CategoryID=62&ArticleID=34&Page=1 18. Q: If we have a representative aircraft that demonstrates the capabilities of our engine, can we use it and accelerate the program? A: Yes, if it is close, we will take a look at it. 19. Q: You say both of these airframes are at Webster Field? A: Yes. Webster Field is near Patuxent River, MD. 20. Q: What is required cruising speed? A: The NOTE: THIS NOTICE MAY HAVE POSTED ON FEDBIZOPPS ON THE DATE INDICATED IN THE NOTICE ITSELF (06-MAR-2007). IT ACTUALLY APPEARED OR REAPPEARED ON THE FEDBIZOPPS SYSTEM ON 25-FEB-2008, BUT REAPPEARED IN THE FTP FEED FOR THIS POSTING DATE. PLEASE CONTACT fbo.support@gsa.gov REGARDING THIS ISSUE.
