Akaflieg Aachen M 1
In 1929, Hermann Mayer designed the "MI” glider. It was built by the glider pilot group of aviation association Aachen in the workshop of the Aerodynamic Institute, and Hermann Mayer took part in the Rhön competition with this design in 1929.
The “MI" was a high-wing strutted in deliberately simple design because it was intended as a training glider.
The “Aviation” 1929, No. 16 reported about this aircraft:
The curb weight of the machine is 118kg and is composed of the following individual weights:
Wings: Centerpiece 22.3 kg, 23.6 kg per outer parts
Hull 29.7 kg
Seat 1.8 kg
V- struts per 4.5 kg
Height Control 5.6 kg
Rudder 2.4 kg
The hull is planked front to rear spar with plywood back covered with fabric. The wing has three parts continuous profile (Göttingen 535), the center piece is braced by V struts.
The ailerons were designed with torsion-resistant plywood nose, allowing most diagonals to be omitted.
Wingspan 14.52 m
Wing area 17.0m
Aspect ratio l : 12.4
Wing loading 70kg pilot weight: 11 kg / m²
It was built by the glider pilot group of aviation association Aachen in the workshop of the Aerodynamic Institute, and Hermann Mayer took part in the Rhön competition with this design in 1929.
The success of Hermann Mayer on the Rhön competition in 1929 prompted the FVA to build an "MI”. This machine was improved in detail and carried the designation "M la”. The design improvements probably come from Hermann Mayer and not by the FVA. The biggest change was an increase in the span of 16.5m compared with 14.5 m of "MI”.
