  1. Transverse Flow Effect and ETL - Vertical Reference Helicopter …

    Feb 2, 2016 · Transverse flow effect or otherwise known as inflow roll effect. Its when the helicopter is moving in any direction,typically forward, and as the movement approaches 11-15 …

  2. Traverse flow, coning and co - Aerodynamics, Mechanics, or other ...

    Jan 1, 2007 · Transverse flow effect is an aerodynamic effect encountered when the helicopter moves (typically forward) through the air. In a hover, the air above the rotor disk is being pulled …

  3. a closer look at Gyroscopic Precession - Vertical Reference …

    Jan 5, 2007 · Transverse Flow Effect on the other hand will occur generally between 10-20 kts for the reasons stated already. I would say that TFE and ETL both tend to get confused with each …

  4. Coriolus Effect? - Aerodynamics, Mechanics, or other... - Vertical ...

    Sep 8, 2013 · At higher speeds it seems reasonable that transverse flow effect is negligible and the vertical stabilizer reduces the need for tail rotor thrust, so left cyclic is no longer needed. …

  5. Transverse Flow Effect in hot weather - Aerodynamics, Mechanics, …

    Jun 29, 2008 · On a hot sunny day, will you have to compensate more for your transverse flow effect than on a chilly day?Thinking about updrafts from heated surfaces. For example, your …

  6. Traverse flow, coning and co - Page 2 - Aerodynamics, Mechanics, …

    Jan 1, 2007 · The way the helicopter is rigged. Transverse flow effect becomes a non factor as airspeed increases, so the right movement of the cyclic in just removing the input required to …

  7. Question on Retreating Blade Stall - General Helicopter Forum ...

    Aug 4, 2014 · Where does the stall begin on the retreating blade? At the root, or at the tip? Then, the golden question is: Why?

  8. Coriolus Effect? - Page 2 - Aerodynamics, Mechanics, or other ...

    Sep 8, 2013 · My understanding of the need for left cyclic when transitioning through ETL is due to an imbalance in lift production between the forward and aft halves of the rotor disc (inflow …

  9. Main rotor coning and forward flight roll.

    Mar 30, 2008 · Transverse flow effect would cause a right roll. (Throwing it out there) Edited May 8, 2008 by CharyouTree Quote

  10. Confined Area Training - Vertical Reference Helicopter Forums

    Feb 8, 2007 · Normally the approach is going to be a steep approach and this is how I teach my students: As soon as you intercept the sight picture for the approach, back your airspeed off …
