3.5. Adjustment of sailplane assemblies and control systems
3.5.1.
General notes
After adjustment of turnbuckles threads may not be visible. When adjusting
pushrod ends it should be checked whether inspection holes are closed by thread.
Deflections and tolerances of deflection of control surfaces and airbrakes are
presented in Fig. 6
‒1. Levelling points are marked with letter „S” in this Figure.
3.5.2.
Adjustment of aileron control system in wing
Adjustment of aileron control system in wing (Fig. 2
‒13.) is done at the
pushrod ends (3) and eventually at pushrod ends (1) and (2) through an opening in
wing root rib.
3.5.3.
Adjustment of airbrake control system in wing
Adjustment of airbrake control system in wing (Fig. 2
‒15.) is done at pushrod
end (1) near the connection with airbrake arm driving lever (7) in airbrake box, and
on pushrod (2) near the connection with bevel gear assembly driving lever (3).
3.5.4.
Adjustment of aileron control system in fuselage
Adjustment of aileron control system in fuselage (Fig. 2
‒12.) is done at
pushrod ends (6) and (7).
NOTE:
Adjustment should be done on fully mounted sailplane with ailerons
and control sticks in neutral position.
Maximum aileron deflections are set using limiters
– regulation screws (4) located at
the front (1) and rear (2) flying control.
3.5.5.
Adjustment of elevator control system
Adjustment of elevator control system (Fig. 2
‒12.) is done at pushrod ends (9),
(10) and (12).
Control sticks
’ neutral position in elevator control system is presented in
Fig. 2
‒12.
Maximum elevator deflections are set using limiters
– regulation screws (5) located at
the front (1) and rear (2) flying control.
