...work in progress...

Environment
Unit: choose between metric and imperial units
Elevation: Elevation above sea level your flyinf field is located.
Temperature: outside air temperature.
 
Drive Data
Propeller Dimensions (diameter, pitch and number of blades)
Revolution: max. propeller rpm driven by the motor (incl. gear)
Static Thrust: measured or calculated static thrust
Climb up to: what height over the field you will climb to.
 
Aircraft Data
Weight: All-up-weight for flight
Fuselage Length: over all length of the aircraft
Fuselage Diameter: estimate the diameter of your fuselage at its widtest section.
Area: the plan area of your wing/tail including the fuselage covered part.
Span: Total wing/tail span.
Thichness: the airfoil thickness in relation to the cord
Gear Area: surface area of the eintire gear ind wheels. for retractable gear insert zero.
   

Interpret the Results 

dynamic flight: the airplane produces lift on the wing and traveld above its stall speed 1g.
static flight: the air plane «hangs» on the prop. the wings do not produce enough lift.

Quick Check Gauges:
Some parameters are additional shown as gauges for a quick overview of the setup.

  • Speedrange: the green band represents the speed range from stall speed (1g) to max. speed in levelflight.
  • Rate of Climb: the maximum rate of climb for dynamic flight
  • Time to Height: the minimum time to climb to defined Height over the field.
  • 3D Capability
    - red: no 3D capability
    - yellow reduced 3d capability to maintain altidude
    - green full 3D capability for all 3D moneuvers
  • Acceleration: the maximum vertical acceleration from stand still
  • Vertical Speed: the maximum achivable speed in a vertical climb

Graphs:
 

The Power Diagram in Level Flight indicated the data with in creasing horizontal speed.
brown: the required propeller power to maintain level at a certain horizontal speed.
violet: sthe maximum abailable static power of the propeller. If the line crosses the green 3D box your aircraft is fully 3D capable. If it crosses the yellow box it is reduced 3D capable and out side any box the aircraft is not 3D capable.
blue: the dynamic available propeller power. the intersection with the brown line represents the aircraft stall speed at 1g and the max. possible air speed in level flight.
grey: the carson line. the best range is at the speed where the carson line intersects the min. power for level flight (brown)

The Dynamic Clim Performance indicated the climb performace in a dynamic flight condition on certain horizontal speed.
brown: achivable rate of climb
blue: achivable angle of climb
violet: the required time to climb to the defined height over the field.

The Static Vertical Climb indicates the performance from a vertical stand still accelerating to the max. vertical speed at max. throttle.
brown: Vertical Speed after a sertain time applying full thrust
blue: Height after a sertain time applying full thrust

 

Der Umgang mit den Resultaten

Kurzanalyse:
Einige Parameter werden zusätzlich als Messuhr angezeigt um einen schnellen überblick der Berechnung zu erlangen.

Anmerkung:
Der Calculator überwacht die max. zulässigen Ströme bzw. Leistung der Komponenten und gibt bei entsprechender Überschreitung eine Warnung an sie. Dies sind KEINE Fehlermeldungen, sondern Warnungen, wo allenfalls Probleme zu erwarten sind. Blau Warnungen sind informativ, rote sind kritisch.
Die max. physikalische Drehzahl wird nicht überwacht.
Bitte beachten Sie immer die Herstellerangaben.
