The wings are from the [[Schleicher ASW 15|ASW 15]] with upper-surface Schempp-Hirth metal air brakes added. Later models received modified brakes with an additional panel to improve effectiveness.
Schempp-Hirth metal air brakes are fitted on the upper surface of the wing, and later models received modified brakes with an additional panel due to the somewhat disappointing effectiveness. The wings are held in place with two main pins. Up to 80 [[kg]] of water ballast can be carried. The tail unit is also of glassfibre/foam sandwich, and the horizontal tailplane has a fixed stabilizer. The fibreglass fuselage is built without the honeycombs that were used on the [[Alexander Schleicher ASW 15|ASW 15B]] and [[Schleicher ASW 17|ASW 17]]. It has a winch hook, which is covered by the main wheel doors, and an aerotow hook situated approximately one foot from the nose.

History
First flight23 November 1975

The ASW 19 is a single-seat glider built by Alexander Schleicher GmbH & Co, first flying in 1975. It was originally designed as a Standard Class glider, but now mainly competes in the Club Class. The ASW 19 is known for its pleasant handling and some clubs use it as a training glider. It was succeeded by the all-new Schleicher ASW 24.

Design

[edit]

The wings are from the ASW 15 with upper-surface Schempp-Hirth metal air brakes added. Later models received modified brakes with an additional panel to improve effectiveness.

The all-new fibreglass fuselage was built without the honeycombs that were used on the ASW 15 and ASW 17. It has a winch hook, which is covered by the main wheel doors, and an aerotow hook situated approximately 30 cm (12 in) from the nose.

The wings are held in place with two main pins. Up to 80 kg (180 lb) of water ballast can be carried. The tail unit is also of glassfibre/foam sandwich, and the horizontal tailplane has a fixed stabilizer.

Variants

[edit]

With the ASW 19b version, the maximum allowed amount of water ballast increased and the take-off weight can be raised to 454 kg. Later ASW 19B were delivered with an instrument panel that lifts with the canopy. This feature can be retrofitted to older models.

The ASW 19 Club is a version with a fixed unsprung monowheel and no water ballast carried. Only five were built for the Royal Air Force, where they were known as the Valiant TX.1.

At the Delft University of Technology a single ASW 19 was fitted with a new wing profile featuring turbulator blow holes. This ASW 19X showed improved gliding capabilities with a best glide ratio of about 41:1.
