Re: [Flightgear-devel] Yasim glider
Hi all, tonight a nice aerotow was performed (thanks to AJ), some winch starts and the J3 as external cargo with the CH47 (thanks to Joacim). I will do some clean up in the code, and add the gravity force of the tow...

I want to add the ability to use ropes. To be used for winch as well as for aerotow. The real challenge is to make it work over MP with a human piloting the tow aircraft. (A winch or a towing ground vehicle could by all means also be human controlled.) Yes, that is the aim. So what's your plan here? Add optional /external/ control of a thruster? Adding a hinch objects to YASim, which can be connected to a tow. The other end of the tow can be connected to a fixed position or an AI/MP-Object. The length of the tow can be modified (- winch). Then it wouldn't matter if it's a towing aircraft being subject to a force pulling backwards or a towed aircraft being subject to a force forward. Same implementation. Yes. It would also work the same for helicopter sling loads. Yes, but we need a cargo-fdm. Or towing with mobile ground vehicles. But where would the simulation of the towing line go? (Stretch, drag, bend, weight, inertia... weak links? As a first step I want to simulate the tow with both aircrafts (for aerotow). First I only want to simulate weight and stretch. A winch wire or a pay-out line doesn't have a constant lenght.) It's not a dead object. A towing line can be released at either end, by the pilot at each end or by a snapping weak link at each end. So it's not really a submodel of any of the objects at the ends of it. Yes. But if it is released by one aircraft, the tow will be ignored by the other aircraft. I think the tow/airlift wire/line object should be it's own simulation instance. -- ? Do you know, if this is already possible in Flightgear? And of course, designing gliders per se doesn't require any patching of any fdm backend. The yasim solver needs a thruster element for determining drag, but the force from that would be the same fwd thrust produced from sink rate + mass and the L/D ratio at best glide or min sink. (easily calculated) L/D ratio and airspeed for best glide performance, and sink rate /airpseed for minimum sink (at a respective weight) are normally published data for gliders. Just pretend gravity is not perfectly vertical when defining approach and cruise... Yes, you can add a thruster and YASim can simulate glieders as it is. But with a very small patch (adding a glide angle to approach and cruise) you don't need the thruster fake any longer. Best regards, Maik - Take Surveys. Earn Cash.
