Merkel Mark II

This two-seat aerobatic biplane is stressed to a +6G and -3G limit, and +9G to -4.5G ultimate. It was first flown in 1973, and its designer, Edwin Merkel, planned to produce the biplane in a two-seater trainer version and a single-place competition model. The Mark II is completely covered with a light alloy skin outside, and underneath the fuselage is welded steel tube while the wings feature a single-spar tor¬sional structure. Other extras include an antiservo tab, ground-adjustable trim tab and optional cockpit canopy.

Meridionali-Aerfer Spa

Meridionali-Aerfer Spa succeeded Societa Aninima Industrie Aeronautiche Romeo, which had been formed in 1934 to absorb Officine Ferroviarie Meridionali’s aviation activities. Became part of Societa Italiana Ernesto Breda group. Developed Ro.37 two-seat reconnaissance biplane which served October 1936 with Italian Aviacion Legionaria during Spanish Civil War and equipped Italian Air Force reconnaissance units during Second World War. Also used operationally were Ro.43 two-seat, single-float catapult seaplane and single-seat fighter version, Ro.44.

Merckle SM-67

First turbine-powered helicopter built and flown in Germany, the five-seat Merckle SM 67 development began as a private venture in 1956, but the third prototype, which flew for the first time on April 12,1961, was bought by the Federal Government and spent much of last year undergoing an official flight test and evaluation programme.

More refined than its predecessors, it has a fully enclosed cabin and is powered by a 406shp Turbomeca Artouste IIC shaft turbine, driving a three-blade main rotor and two-blade tail rotor.

The Merćep 1912 aka Merćep-Rusjan Military-Monoplane of 1912 or Rusjan-Novak No.2, was the second design after the crash of the Slovenian aviation pioneer Eduardo Rusjan. Earlier, Eduardo Rusjan had moved with his brother to Zagreb, Croatia, where Guiseppe Rusjan and Dragutin Karlo Novak then continued to build aircraft for the “Agramer Aëroplanfabrik M. Merćep”, set up by the businessman Mihajlo Merćep in Zagreb.

Mercedes D.IV

The Mercedes D.IV was an eight-cylinder, liquid-cooled inline aircraft engine built by Daimler Motoren Gesellschaft (DMG) and used on a small number of German aircraft during World War I.

The design was based around the pistons of the ubiquitous D.III 6-cylinder design and developed 162 kW (217 hp), making it a Class IV motor under the classification system then in use in Germany. When the reliability of the engine proved disappointing, it was supplanted in production by the unrelated six-cylinder Mercedes D.IVa. Specifically, the long crankshaft used in extending the original straight-six design to a straight-eight proved susceptible to breakage.
