1 My Background Flying RC sailplanes since 1976 First competition 1977 US Nationals, placed 2 nd Only pilot to win world champion for both FAI recognized soaring disciplines FAI world record holder for declared distance to a goal (141 miles, set in 1988) A lifer in the sport Joe Wurts 1

2 Finding and Recognizing Thermals Joe Wurts Joe Wurts 2

3 Topics of Discussion Thermal Theory Application Thermal Sources Non-Thermal Lift Joe Wurts 3

4 Thermal Theory - Basics Basic definition: lighter than the surrounding air Thermal shapes Column Bubble Disorganized blob Streets Joe Wurts 4

5 Thermal Theory - Climate Influences Humidity Ground moisture Lapse rate Inversion height Cloudiness Joe Wurts 5

6 Thermal Theory - Characteristics Feeds from warm air near the ground Drifts with the wind Attraction to other thermals Thermal aspect ratio Joe Wurts 6

7 Application - Clues to Finding Thermals Detecting thermal inflow Inflow signs Wind lulls, changes Wind shifts» Do not confuse with thermal inflow Ground signs Look for the third vector Wind Thermal Inflow Wind What you feel (Wind + Inflow) Inflow Joe Wurts 7

8 Application - The Third Vector Mental vector math = Direction to thermal Thermal Wind = What to look for Temporary changes in the wind» Direction» Speed Wind + Inflow = What you feel Wind Inflow Joe Wurts 8

9 Application - The Third Vector Mental vector math = Direction to thermal = If you are Thermal Inflow standing here... The wind if there was no thermal Wind Thermal What you feel Inflow (The third vector) The wind + thermal inflow = the wind that you feel Joe Wurts 9

10 Application - The Third Vector Mental vector math = Direction to thermal Do the math to derive the direction to the thermal What you feel Wind Wind Inflow (this points to the thermal) Inflow Note the wind speed and direction that you feel Subtract the basic wind The result is the change caused by the thermal Joe Wurts 10

11 Application - Practical Guidelines Sharply defined upwind edge Diffuse downwind edge Convergence zones Angled streets Wind Joe Wurts 11

12 Application - Perspective Challenges Confusion between range and altitude Elevation angle confusion Wind Joe Wurts 12

13 Altitude Application - Hints on Recentering Turn tighter in the stronger lift Constantly reevaluate on each circle Be wary of subconscious upwind drift Effects of horizontal wind shear Wind Wind Speed Joe Wurts 13

14 Altitude Altitude Altitude Morning Conditions - Inversions Typical wind profile with altitude Wind Speed Wind profile low level inversion Temperature profile low level inversion Temperature Inversion Temperature Inversion Wind Speed Temperature Joe Wurts 14

15 Thermal Sources Heating sources Drier ground Radiation sources Terrain influences Tree lines Hills Wind Joe Wurts 15

16 Non-Thermal Lift Wave Conditions necessary When likely Shear line Hydraulic wave Dynamic soaring Joe Wurts 16

17 Optimizing Your Aircraft Set-up HOW THE HECK DO I GET THIS THING TO WORK? Joe Wurts Joe Wurts 17

18 Topics of Discussion Philosophy The Mechanical Aspects Mixing Flight Modes Joe Wurts 18

19 Philosophy Optimizing the aircraft efficiency and performance Minimizing drag Getting the most capability Eliminating the cross-talk in inputs Goal is coordinated flight without difficulty Ease of Control Ease of flying = more performance realized Joe Wurts 19

20 The Mechanical Aspects Servo installation Install servos to get straight pushrods Servo linkage and throws Stiff and tight linkage without drag Wiring suggestions Note servo arm angle forward and control arm angle aft, produces progressive mechanical differential - good for ailerons Joe Wurts 20

21 Mixing - Roll Axis Goal - Coordinated roll w/o separate rudder Aileron to Flap mixing Increases roll efficiency (I use Flap = 40% Ail) Differential vs Rudder coupling Best help in setup - slope on a light day Slow speed vs high speed Dependence on aircraft configuration Typical 1.5:1 to 2.5:1 differential Joe Wurts 21

22 Mixing - Pitch Axis Primary mix is Elevator to Camber Camber should be even across the wing If possible, use an inverse exponential mix» More camber mix initially A good start is full up mixes to 10 camber» Highly dependent on airfoil usage Vee Tails More down throw than up for a symmetric pitch response Joe Wurts 22

23 Mixing - Yaw Axis Vee Tails Rudder mix typically needs reverse differential» The more vertical, the more reverse differential Less efficient than a cross-tail Mostly covered in roll axis Reverse Differential Joe Wurts 23

24 Flight Modes I use four flight modes Launch Speed Cruise Thermal Each mode has a different, ail>rud mix, differential, camber and elevator preset, as well as control throw setting Joe Wurts 24

25 Flight Modes - Launch Camber preset 15 to 30 camber preset (full span) Dependent on airfoil usage Elevator preset Highly dependent on towhook position Neutral to slight amount of up is best Aileron to Rudder mixing More is better Up to 100% aileron differential Joe Wurts 25

26 Flight Modes - Thermal Camber presets or adjustments I use flight mode presets, with adjustable slide for fine tuning Camber to (Ail to Rud) gain adjustments More camber should give more Ail to Rud gain Elevator to Camber mix Keep this mix (many people do not) Aileron to Rudder mix Go to a higher rate for slow speeds Reduced Aileron and Elevator throws Joe Wurts 26

27 Flight Modes - Speed Reflex Camber settings (fallacies) Elevator to Camber mix Use a bit more (higher loads cause blow-back ) More if using reflex camber preset Aileron to Rudder mix Minimize this Differential changes Possibly a reduction is warranted Joe Wurts 27

28 Flight Modes - Landing Flap to Elevator mix Highly non-linear after 45 flap Flap to Aileron (crow) I use about 10 up aileron Aileron to Rudder mix Add some to suit Differential adjustments Typically a bit more is needed Goal of crow/ail>rud/diff is slightly proverse yaw response with a roll input Pitch up is caused by downwash on the elevator 0 Flap Throw 90 Joe Wurts 28

29 Launch Optimization Joe Wurts Joe Wurts 29

30 Topics of Discussion Launch Modelling Program Aircraft Set-Up for Launch The Throw The Zoom Winch/Line Optimization System Losses Steering on Tow Crosswind Launching Circle (Weave) Towing Joe Wurts 30

31 Launch Modelling Program Baseline Assumptions Straight tows only (no weaving) Power on 100% Default data: Weight 96 oz Aspect Ratio 12.5 Wing Area 7.0 ft 2 Throwing Line Ten 50 lb. Launch C l 0.80 Wind Velocity Zoom Point Winch Drum Dia 10 ft/sec 75 deg up from turnaround 3.5 inches Joe Wurts Typical Launch

32 Aircraft Set-Up for Launch Full-span launch camber typically 20 to 25 Elevator pre-set Most fliers have too little up pre-set and/or towhook too far forward More Aileron to Rudder mix Tow hook position (very important) Optimum needs just a little up pre-set Joe Wurts 32

33 The Throw In general, as hard as possible with as much tension as possible Exception - circle towing Should be more vertical Variation in initial tension and velocity 25 ft/sec 50 lbs 50 ft/sec 100 lbs Joe Wurts 33

34 Effect of Zoom Position Zoom start point from 50 to 95, measured from the turnaround Zoom early in the wind (30 ft/sec wind 900 optimum is 60 ) Multiple zooms wind=10 ft/sec deg 55 deg 60 deg 65 deg 70 deg 75 deg 80 deg 85 deg 90 deg 95 deg Joe Wurts Multiple zooms wind = 30 ft/sec deg 55 deg 60 deg 65 deg 70 deg 75 deg 80 deg 85 deg 90 deg 95 deg

35 How Deep to Zoom It is better to be too shallow than too deep The pullout is very expensive in energy Deeper = faster (and draggier) Start your pullout with 10 to 20 lbs tension Best with a slight pop of the chute Go to nearly vertical quickly (hard pull-out) Fast transition from high drag to low drag Joe Wurts 35

36 Winch Optimization Use the correct drum size for the conditions Use the right resistive material Try Constantin Minimize losses in the system Heavy duty selenoid Large, short cabling Launch Height, ft Wind 0 Wind 10 Wind 20 Wind Drum Dia, in Joe Wurts 36

37 Line Optimization Line size Use the minimum size that wil not break Stretch characteristics Optimum line for wind is different than no wind Line that has some plasticity is good for weaving in the wind Rebound characteristics Some lines do not spring back quickly Joe Wurts 37

38 System Losses The biggest is line drag in the air Minimum line size for the conditions Maximize C l capability on tow Parachute drag is important Minimize parachute and shroud size Try double-hooking Aircraft set-up can have a factor (Trim C l ) Joe Wurts 38

39 Steering on Tow Being on tow is similar to flying very slowly (high C l ) You should use a lot of rudder along with a little aileron When there is little tension, the plane might need some down elevator Note line tension is behind the CG Joe Wurts 39

40 Crosswind Launching The optimum launch is from straight downwind of the turnaround As soon as is practical after the throw, turn the aircraft to get downwind of the turnaround Then turn back up the tow to finish the launch A side benefit is that you can better gauge your zoom dive/pullout Joe Wurts 40

41 Circle (Weave) Towing The basic idea is to use the energy of the wind instead of the winch motor Line that stays off of the drum helps your launch height Tension is everything Use weaving to build tension and gain altitude Joe Wurts 41
