Aaron Posted February 14, 2003 Share Posted February 14, 2003 High all, I'm running some heat calculations and need some real world numbers. Please let me know what fuel flow numbers you've observed either in max climb or fast cruise, and also what your best HP estimate is I'll be running fuel flow numbers through a simulator to determine the overall heat balance. Thanks in advance, Aaron Quote Link to comment Share on other sites More sharing options...
Aaron Posted February 17, 2003 Author Share Posted February 17, 2003 10 gph? 16 gph? any ideas at all? My approach is to do an overall heat balance based on fuel flow and a ratio of air. I combust the fuel, then remove energy (power) for the engine load, then I cool the exhaust gasses to ~1450 F. The heat duty required for this cooling should be close to the actual duty required from both cooling systems. Quote Link to comment Share on other sites More sharing options...
John Slade Posted February 17, 2003 Share Posted February 17, 2003 I seem to remember Tracy Crook saying he gets around 8 GPH on a fast cruise. Quote I can be reached on the "other" forum http://canardaviationforum.dmt.net Link to comment Share on other sites More sharing options...
marbleturtle Posted February 17, 2003 Share Posted February 17, 2003 Richter said he was getting 10-11 gph... he said he would cruise wide open. John would know for certain, but I think Richter was running a Garret T-06 turbo on a 89 13B. Quote This ain't rocket surgery! Link to comment Share on other sites More sharing options...
Aaron Posted February 17, 2003 Author Share Posted February 17, 2003 Greg was running A T04, though he didn't specify trim. (T04 designates the housing, there are different impeller/compressor wheels for different applications) Thanks for the info, that jives well with Tracy's 8gph (NA) number Quote Link to comment Share on other sites More sharing options...
