Tatra Aircraft Designations - Závody Ringhoffer-Tatra as*

The Ringhoffer-Tatra Works of Prague (Praha-Smíchov) produced a range of aircraft and aero-engine designs in the late 1930s. Both aircraft and engines had 'T' prefixed type designations.

Tatra applied a separate 'T' series designations to licensed-built aircraft. The licensed Avian's T.126 designation seems to be a corruption of Avro's Type 626. The T.131 designation took its number directly from the Bücker Jungmann.

Designations for original Tatra aircraft designs ran in two series -- both beginning with 'T'. The first series had a model number following two zeros. The second series followed the more usual Czechoslovak '100' series pattern. Most sources show a hyphen between the 'T' and type number with a period between type number and construction number.

Tatra aero-engines followed a similar pattern to the second series of aircraft designs. This leads to some confusion -- there being both a Tatra aircraft and an aero-engined designated T-101! Tatra engines were also listed by production number -- eg: the T-100 (licensed Hirth HM 504) with a contruction number following as 100.01, 100.02, etc.
