Discussion Overview

The discussion revolves around the concept of applying an electrostatic field to the wings of a remote-controlled (RC) airplane to test its aerodynamics. Participants explore the feasibility of this idea, considering various environmental conditions and experimental setups.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant proposes building an RC plane with an electrostatic generator to test aerodynamics with and without an applied static field.
  • Another participant suggests that the experiment may only be feasible in low humidity conditions, warning that the plane could become a "flying dust ball" and emphasizing the need for smooth wing surfaces.
  • A different participant mentions that magnetohydrodynamic boundary layer control has been used to avoid flow separation in conductive liquids, implying potential relevance to the discussion.
  • One participant expresses skepticism about the RC plane's ability to provide meaningful data, recommending controlled environments like wind tunnels or free flow testing in front of a car for accurate measurements of lift and drag.
  • It is noted that plastic coverings on RC planes can accumulate charge during flight, which may affect the experiment.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and effectiveness of the proposed experiment. There is no consensus on whether the approach will yield useful results, and multiple competing perspectives on experimental methods are presented.

Contextual Notes

Limitations include the dependence on environmental conditions such as humidity, the need for controlled airflow for accurate measurements, and the potential for static charge accumulation affecting results.

Here’s my idea:

I want to build a RC plane.
Inside would house an eStatic generator.
The wings of the plane to be made from aluminum.
A high-voltage static field would be applied to the wings during flight - turned on/off by the remote.

I’d like to test the aerodynamics of the plane with and without an eStatic field aplied to the wings.

Has anyone here done this - before I get started on this experiment?

I think it would be possible only if flown in very low humidity conditions. Then I suspect you’ll shortly have a flying dust ball. Of course in dry conditions the airplane may acquire a static charge simply by moving through the air. In any case the wing surfaces must have no sharp edges, especially points. In short I don’t think it’s feasible. You might try a bi-plane configuration where you can maintain an e-field between the wings if that’s any help.
 
You should know it has been employed yet the magneto-hidrodinamic boundary layer control, in order to avoid the flow separation. It works with conductors liquids.
 
Hi

I don't think using an RC plane is going to tell you anything because you won't be able to measure lift or drag in a controlled airflow.
I have flown RC soarers compedativly and can tell you flight times
can vary from 2 to more than 40 min so duration is not going to tell you anything either.

You have 3 choices

1. Test in a wind tunnel.

2. Mount a model in the free flow in front of a car so you can control incidence and airspeed and lift, drag and moment forces and conduct
your tests in very still conditions on a good flat and isolated road.

3. Try and find some test or study report where this has been done before.


Ps. Plastic heat shrink coverings comonly used on RC planes can charge up
in flight.

Regards,
Ken
