Indraéro Aéro 30
Encyclopedia
The Indraéro Aéro 30 is a single seat, single engined sports biplane
designed in France
in the late 1960s. Only one was built.
It is a small, single seat biplane powered by a 45 hp (34 kW) Salmson
radial engine
, with an entirely wooden structure. The fabric covered wings are staggered
, of parallel chord and without sweepback, dihedral or flaps
. The Aéro 30 is a single bay biplane with its lower wings attached to the bottom of the fuselage and the upper wing placed well above the fuselage by a pair of single, streamlined interplane struts. Further bracing joins the lower fuselage to the upper wing near the top of the interplane struts, assisted by other struts between the upper fuselage and the wing centre section. The cantilever tail surfaces are plywood covered. The vertical tail is tall and straight tapered. The elevators carry trim tabs
.
The fuselage is also plywood covered, the lower part flat sided but with curved decking. This is deep enough immediately aft of the cockpit to meet the top of the single piece, rear-sliding canopy but tapers towards the tail. The undercarriage is fixed, with a rear tailskid. The main legs are attached to the fuselage just ahead of the wing leading edge and have steel spring shock absorbers. No brakes are fitted.
Biplane
A biplane is a fixed-wing aircraft with two superimposed main wings. The Wright brothers' Wright Flyer used a biplane design, as did most aircraft in the early years of aviation. While a biplane wing structure has a structural advantage, it produces more drag than a similar monoplane wing...

Design and development
Design and construction of the Aéro 30 began in the autumn of 1967. It first flew on 23 September 1968 and received its amateur category SGAC certification in that October.It is a small, single seat biplane powered by a 45 hp (34 kW) Salmson

Stagger (aviation)
In aviation stagger refers to the horizontal positioning of a biplane, triplane, or multiplane's wings in relation to one another.An aircraft is said to have positive stagger, or simply stagger, when the upper wing is positioned forward of the lower wing, such as the de Havilland Tiger Moth or...

Flap (aircraft)
Flaps are normally hinged surfaces mounted on the trailing edges of the wings of a fixed-wing aircraft to reduce the speed an aircraft can be safely flown at and to increase the angle of descent for landing without increasing air speed. They shorten takeoff and landing distances as well as...

Trim tabs
Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aero-dynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the...
