    Span loading and Aspect Ratio vs glide ratio

    Hi everyone! To illustrate my question lets just try an exaggeration : 2 airplanes with the same span loading, both have equal wingspans and equal gross weights. One has an AR of 1:1 while the other has an aspect ratio of 10:1. Which one has the better glide in power off mode ? I...

    The ULTIMATE and FINAL VTOL to end them all!

    Hi, lets just face it. A super aircraft MUST and I mean MUST be VTOL capable. Now let us imagine that we have very lightweight electric engines that DO NOT REQUIRE power and will run forever without a drop of fuel/battery(now I know of many phony claims from inventors etc but this is not...

    Glide-ratio and Engine out scene.

    Hi everyone, I have been wondering about the case when an engine cuts out. Let us assume that an airplane loses engine power at a good medium altitude. the thing that makes me scratch my head is what really is BEST in only this situation, a very good gliding ratio or an as steep...

    How to calculate static thrust?

    Hi, everyone, there are plenty of thrsut calculators that give you rpm, thrust, tip speed, but not how much power to be required? if it was all about direct driven electric motors, that would be no problem but what about calculating how much a 582 or 60hp engine with a gearing toa 120" prop...
