flap angle

At 0133, the flap angle was increased; the aircraft then began to fall below the approach slope and was travelling faster than the crew thought.

The inner split flaps were electrically operated and had a maximum flap angle of 55 .

Flight tests showed that with the slats open at maximum flap angles the minimum flight speed decreased by 30%.

It will also increase the difference of thrust between the advancing blade and the retreating blade that will then increase the cyclic flapping angle.

As the rotor thrust is, at first order, perpendicular to the tip path plane, an increase of the cyclic flapping angle will tilt the thrust rearward.

Same as Streak SL, but with increased flap angles and other minor changes to lower stall speed, putting it into UK Microlight category.

Checking the flap angle showed that it had traversed through 26.5 degrees so I opened up the fuselage flap slots until I had 27 degrees of movement.

Specific design features include a fully harmonized rotor, a modulated collective pitch system, very low twice-per-revolution vibration level due to elastomeric thrust bearings, a sufficient flapping angle for low-"G" maneuvers and slope landings, control friction devices, and an electronic throttle control (governor).
