Junkers T.19 / T.23 / T.26 / T.27

The Junkers T.19 / T.23 / T.26 / T.27 were a two-seat, single-engine experimental training aircraft, built in Germany in the early 1920s.

It could be configured either as a parasol winged monoplane or as a biplane to compare handling characteristics.

Variants

T 19

The T 19 first flew on 14 July 1922, powered by a 55 hp (41 kW) Siemens-Halske Sh 4 5-cylinder radial engine.

Two more T 19s were flown, one with a 77 hp (57 kW) 7-cylinder Sh 5 engine and the other with a 110 hp (82 kW) 9-cylinder Sh 12.

The second T 19 was used as an engine test bed and was the first aircraft to fly with Junkers’ first flight petrol engine, the air-cooled 75 hp (56 kW) 6-cylinder inline L1 of 1921.

It also flew with a 1926 Armstrong Siddeley Genet.

The third T 19 was sold to India.

Junkers T 23D

The biplane version of the aircraft.

Junkers T 23E

The monoplane version of the aircraft with the lower wing not fitted.

Junkers T 26 

An aerodynamically refined version of the T 23, powered by an air-cooled Junkers L1a 62 kW (83 hp) 6-cylinder inline engine.

The latter was mounted in a circular cowling like that used on the T 19, its diameter determined by the large circular blower on the front of the L1a, with cylinder heads exposed.

This installation increased the length by 280 mm (11 in). Like the T 23, it came in D and E configurations. Slightly slower than the T 23 but almost double the range (345 km, 214 mi).

It was again too expensive for flying schools.

It first flown 23 October 1923.

No more than 11 were built.

Junkers T 27

A single T 26D was re-engined with a 95 kW (128 hp), 9-cylinder Clerget 9Z, flying in 1925.
