Pichler - Musger Mg-19B / 2933 mm wood building Kit

Description

The Oberlerchner Mg 19 Steinadler is a two-seat tandem trainer aircraft designed by Erwin Musger, built in Austria and first flown in 1951. Several examples of this successful aircraft, which took part in two world gliding championships in the two-seat class in the 1950s, were still flying in 2000.

In the 1930s, Erwin Musger was an important Austrian glider manufacturer. His first two-seat design was the Gullwing Musger Mg 9, which set a world flight record in 1938. The Oberlerchner Mg 19 was a post-war development of the Mg 9, financed by the Austrian industrialist Joseph Oberlerchner, with a medium/low wing instead of a high wing. The change in wing position was made primarily to improve upward visibility from the rear seat, which was blocked by the wing on the Mg 9. The wing roots are carefully fitted into the fuselage to avoid airflow turbulence, and the 10° V-shape in the inner third of the span ensures that the wing tips are well clear of the ground, although the outer panels only have a 2° V-area had.

Like the rest of the Golden Eagle, the two-piece cantilevered wings are framed in wood and covered in a mix of plywood and fabric. Each piece is built around a single spar, with the layer in front of it covering the leading edge and forming a D-shaped torsion box. Behind the spar, the wing is covered in fabric, except for smaller areas near the root and near the tip where the aileron joint is angled toward the spar and requires reinforcement. On the earliest model, the Mg 19, the ailerons fill the trailing edge from bend to tip, but such a large area creates high control loads and on the Mg 19a the ailerons are reduced in length by about a third. Schempp-Hirth air brakes open above and below the wing just inside the curve at 44% wing depth. In plan, the wing has a straight and curved front edge. The trailing edge also runs straight inside the ailerons, where the tips become semi-elliptical. A 1° turn on a quarter chord creates a curved spar so the two ends can meet just behind the back seat.

On the later models, the gull wing is replaced with one with a constant 5° V-shape, with no change in ground clearance at the tip, although ground clearance is low with the airbrakes extended. Otherwise the wing of the Mg 19b is unchanged. The wing of the Mg 19c competing in the World Gliding Championships is different, with straight, tapered outer wings, small tip bodies and a section that is a mix of the NACA 64-2015 laminar airfoil and the older, proven Göttingen 549.

The Golden Eagle was used by many Austrian clubs and set most national two-seater records until 1963. Several remained in service fifty years after the first flight and eleven remained registered in the Austrian civil status register in 2009.

The only Mg 19c took part in the 1956 World Gliding Championships in Saint-Yan, the last WGC to have a separate category for two-seaters.

Our model implementation of the Musger has been very successful and we offer a drive solution.
