shams42 Posted April 10, 2017 Report Share Posted April 10, 2017 I made a figure comparing the published polars from the Phoenix against the Sinus, the PW-5, and the ASW-27. I got the numbers from the figures published in the POHs, and I have doubtlessly introduced some interpolation errors. I've attached the Excel spreadsheet I used as well as a plot of the data (produced using R / ggplot2). I hope you find this interesting. The result seems to indicate (to me, at least) that the Phoenix is quite a capable glider. Benchmarking against the ASW-27 is silly, of course, but I wanted to see how much it gives up against a high-performance pure glider. A more even comparison would pit the Phoenix against other two-seat gliders. polar_comparison.xlsx Quote Link to comment Share on other sites More sharing options...
shams42 Posted April 11, 2017 Author Report Share Posted April 11, 2017 I added the Caret and Lambada gliders to this comparison. The Caret is a little better than the Phoenix in slow flight; the Phoenix is a little better at speed, though they are quite evenly matched. However, the Caret is a one-seater with retractable gear and a folding prop. polar_comparison.xlsx Quote Link to comment Share on other sites More sharing options...
Registered Eric Greenwell Posted May 8, 2017 Registered Report Share Posted May 8, 2017 Very nice to see the plots together. What we really need is some comparison flying; eg, Phoenix vs Carat, Phoenix vs PW5. My suspicion is the Carat is better than the Phoenix at every speed, as it is hard to imagine a retractable gear glider would become worse than a fixed gear glider at high speeds. There aren't any Lambada, Carat, or PW5 in my area, so I can't help out. Quote Link to comment Share on other sites More sharing options...
