horn balance

Both rudder and elevators had horn balances which projected beyond the fixed surfaces.

After some testing the rudder was modified with a horn balance and larger ailerons were fitted.

Larger horizontal tail surfaces were adopted, with larger elevator horn balances.

Both horizontal and vertical surfaces were rather rectangular, but the rudder had a noticeable horn balance.

The rudder was balanced, but the ailerons and elevators lacked horn balances.

The fin and rudder are curved, the rudder having a horn balance.

Tail surfaces were conventional, apart from the rudder horn balance positioned under the rear end of the fuselage.

The braced tailplane had significantly greater elevator than stabiliser area, the former again having prominent horn balances.

The first production aircraft also used this engine but had some small horizontal control surface modifications plus the addition of a horn balance to the rudder.

The wing tips were essentially square, except that the horn balances of the short span ailerons on both upper and lower wings projected beyond.

The landing gear was strengthened with twin main-wheels and the fins were more rounded, lacking the characteristic horn balance nick of the earlier models.

Ailerons were fitted on both wings and as on the Bourges their horn balances projected beyond the wingtips.

Only the upper wings carried ailerons; these narrowed in chord outward before rapidly widening at their tips to form horn balances.

The elevator horns were also smaller in size than that of most Mk IXs which had larger horn balances.

The rudder had a large horn balance that overhung the fin and its unusual forward extension that acted as a trimming surface.

Flight testing also showed that the rudder was aerodynamically over-balanced, causing oscillations cured by removal of the horn balance entirely.

Ailerons were fitted only on the upper plane and were short span and overhung, that is, their horn balances projected beyond the wing tips.

It had unequal span, single-bay wings, with ailerons on the upper wing only with large horn balances (the amount of control surface forward of the hinge).

Fin area was small and the rudder large, with a horn balance initially merging into the fin but later reduced, leaving a prominent step rather like of the Nautilus.

The rudder, with a swept trailing edge, has a horn balance extending forward of the hinge line under the fuselage, where it is faired into a small ventral fin.

Initially both these machines had Grebe style rudders, squared off with no balance; these were later replaced with Gamecock rudders, vertically extended to include a horn balance.

There was fixed fin surface both above and below the fuselage and the rudder with its horn balance was proud of the upper fin and extended down to the lower part.

Here, the tailplane was located on top of the fuselage and also braced on each side with [pairs of parallel struts; its elevators had rounded tips which served as horn balances.

The third sheet calculates the increment to the derivatives from a horn balance and the last sheet provides the procedure for treating the effect of a tab. A worked example illustrates the use of the calculation procedures.

Tail surfaces consisted of a narrow-chord fixed horizontal surface with a much broader elevator with horn balances hinged to the trailing edge and a balanced rudder which extended below the sternpost and carried a small float.
