High Lift Airfoil - RC Groups

Dec 14, 2009· High Lift Airfoil i will be entering a heavy lift challenge in 2010 with a group from university and we are currently trying to find a suitable airfoil to use. We are limited to the airfoils on compufoil 3D and as far as my research tells me, the eppler 214 is going to be the best one for producing the most lift.

Gurney flap - Wikipedia

The Gurney flap (or wickerbill) is a small tab projecting from the trailing edge of a wing. Typically it is set at a right angle to the pressure-side surface of the airfoil and projects 1% to 2% of the wing chord. This trailing edge device can improve the performance of a simple airfoil to nearly the same level as a complex high-performance design.

STOL CH 701 High-Lift Wing Design - Zenith Aircraft Company

The STOL CH 701 uses a special airfoil design to achieve very high lift, low stall speeds, and high strength. A thick wing, full-length leading-edge slats and trailing edge 'junker' type flaperons develop a maximum wing lift coefficient of 3.10, while maintaining a short wing-span – for maximum strength and ground maneuverability.

High Lift Airfoils for Slow Plane | HomeBuiltAirplanes

Apr 07, 2014· I'm been considering a moderately high lift airfoil for a non-flapped slow flying airplane that cruises around 120mph and lands at 50mph. Although some airfoil have very high CLs (Coefficient of Lift) topping out at around 2.5 on X-foil they also have a …

glider - Why are birdlike airfoils not used? - Aviation ...

In order to combine fast flight with high lift for take-off and landing, the thick airfoil is better. While birds are small enough to structurally get away with thin wings, the much larger man-carrying airplanes need the thicker wings to accommodate their bending loads without bracing.

General Concepts for RC Aircraft Design - NextCraft

• Use symmetrical airfoils with a thickness of 10% to 15% for most aerobatic planes. (i.e., an Eppler 168 or NACA 0012) • Use a semi-symmetrical airfoil for more "scale" performance, including higher potential lift. (i.e., an Eppler 197 or Selig 8036) • Use a thinner airfoil with more camber, for slower flight, such as a …

High LIft Capacity Payload Carrying RC Plane : 5 Steps ...

Airfoil Name: S1223 . 1) High Cl v/s α. 2) Cl v/s Cd ratio. On experimenting it was observed that this airfoil has brilliant glide slope, which becomes a very essential factor when we approach the plane to land with high amount of payload. Therefore, S1223 was chosen to meet the requirement of high …

High lift airfoil for heavy lift - RCU Forums

Mar 20, 2009· Aerodynamics - High lift airfoil for heavy lift - Hello, My son is entering a heavy lift competition this year. I understand that the preferred airfoil is a Selig 1223. Does anyone have the lift/drag/ moment curves for this airfoil? He is thinking of building a tandem wing with both wings of the same area. Is this a

aircraft design - How to select the most efficient airfoil ...

The early airfoils (like Clark Y) are more robust and tolerate more building errors. If you optimise an airfoil for one lift and one Reynolds number, the optimum will require a very high truthfulness of the actual surface contour to the calculated ideal contour. $endgroup$ – Peter Kämpf Jun 23 '18 at 4:53 |
