Avia LD-40

The Avia LD-40, designed and built by the former Avia factory of the Czechslovak nationalised aircraft industry in 1954, is a four-seat cabin monoplane of all-metal construction and powered by a 105 hp Walter Minor 4-III engine. A feature is the reverse tricycle undercarriage, the normal nosewheel being replaced by a wheel mounted immediately aft of the wing trailing edge. The main wheels are mounted well forward below the wing and, on the gound, the Avia LD-40 remains in flying attitude.

The LD-40 accommodates four people on two side-by-side bench-type seats, and the cockpit canopy slides backwards.

Avia M137 / M337 / Walter M 337 / LOM M 137 / M 337

M 337

The Avia M 337 (originally designated the Walter M337) is an inverted six-cylinder air-cooled inline engine. It was developed as a six-cylinder derivative of the four-cylinder M 332 engine, going into production in 1960. An unsupercharged version of the M 337 is designated M 137. Production transferred to Avia in 1964, and to Letecke Opravny Malesice (LOM) in 1992.

Variants:

M 337A
Basic supercharged engine – not rated for aerobatics

M 337R
Modified for pusher installation

M 337AK
modified oil system for unlimited inverted flying. “Snap” aerobatics permitted.

M 337AK1
AK fitted with alternator instead of generator

M 337B
Increased max running speed (3000 rpm) – increased power – 173 kW (235 hp).

M 337BK
Aerobatic version of B.

M 337C
Increased compression ratio – 185 kW (252 hp)

M 137A
Unsupercharged version of M 337 – 134 kW (180 hp) take-off power. Aerobatics allowed.

M 137AZ
As M 137A, with filtered air feed

Avia Rk.17

As well as producing aircraft and building Hispano-Suiza and Lorraine aero-engines under licence, Avia also designed and built their own radial engines. The Rk.17 was a 9-cylinder supercharged model, rated at 360 hp / 270 kW. It was a nine-cylinder version of their Rk.12.

It was a conventional air-cooled radial: nitrided steel barrels with integral fins were screwed into heat treated Y alloy heads. The pistons were also of heat treated Y alloy. The crankcase was cast from heat treated silumin alloy, with some minor parts using magnesium alloy. The single throw two piece crankshaft was linked to the pistons with an I-section Y alloy master rod, with a single piece big end, which carried the other eight piston rods.
