In reality, the SWIRL ANGLE does NOT change with propwash speed or longitudinal location along the propwash stream tube, so tracking this swirl ANGLE in X-Plane instead of swirl SPEED gives us the most accurate propwash swirl in all locations, no matter how far behind the prop.
The insight here was to NOT track propwash swirl in meters per second, but instead track it in degrees of swirl from straight aft! Now we have thew swirl angles at all radial distributions dialed in! Some of this wake turbulence tech comes from Xavion, where I developed it to avoid (another) wake-turbulence hit in the real airplane.īetter propwash swirl based on 4 different tech reports! Wake turbulence, better to track other planes!Ĭommand-m to see wake turbulence from your plane and others when in flight.ģ-D per-plane wake turbulence following wind and settling profile! We find it to be about 0.10 for the PT-6 turbines, and is almost certainly very close to 0 for any reciprocating engine. TURBINE AND RECIP EXHAUST HORSEPOWER TO POUNDS OF THRUSTĮnter how many pounds of thrust the exhaust puts out per horsepower output of the engine. Now we have EXHAUST THRUST as well for the turbines and recips! So while the metar or real weather or other weather setting sets the wind at 10 meters (the wind sock height), the profile from that down to the ground (by definition 0 for the atoms touching the pavement, and a curve in between) follows the wind turbine wind profile model This is from data on wind above ground carefully compiled for wind turbines!!! Har! New wind PROFILE from wind sock to ground So the glider raises a wing in the edge of a thermal. Thermals for gliders are found per element now, Which is cool and causes a little bit of settle as you start to get going before ETL. Rotor bouce back in ground effect now modulated by forward speed. This really drops a wing more in the stall! Stall is now TRIPPED and you really have to lower the nose to recover the non-separated flow, as per reality.
