The DG Flugzeugbau DG-1000 is a two-seater class glider built by DG Flugzeugbau. It first flew in July 2000 at Speyer in Germany.[1] There are four models, with 18- and 20-metre wings[1] of HQK-51 profile. The latest DG-1001 variant replaced the DG-505 in production.[2]
With 18 m (59 ft) span wings it is fully certified for aerobatics ( 7 -5 g); with a 20 m (66 ft) span wings it is certified for limited aerobatics ( 5 -2.65 g).
The engine (DG1000T) is mounted on a pylon aft of the double cockpit. There is a reduction gear (2.3:1.0) between the engine and the two-blade carbon-fibre composite propeller. The propeller was designed by and made in the DG factory.
Operational history
[edit]In 2011, the DG-1000 was selected by the USAF as a replacement for the Blanik TG-10. It will serve as a basic soaring trainer for cadets at the United States Air Force Academy. It also serves as the primary competition platform for the USAF Academy Aerobatic Demonstration Team. Its USAF designation is TG-16A.[3][4]
Variants
[edit]- DG1000S
- Basic unpowered variant, two or three wheel configuration, with provisions for a retractable landing gear. [5]
- DG1000T
- Retractable pylon-mounted engine, aft of the cockpit, with a 2.3:1 reduction gear driving a two-blade carbon-fibre composite propeller, designed and produced by DG.
- DG-1001
- Refined version with electric landing gear retraction.[6]
- DG-1001e neo
- fitted with front electric sustainer – due to fly 2020.[7]
- TG-16A
- USAF designation. Used to train cadets in soaring at the United States Air Force Academy, replacing the LET TG-10 Blanik.[4]
- Akaflieg Karlsruhe AK-9 or
- A 0.400 kN (90 lbf) turbojet engine was installed in a two seater DG-1000. In Cooperation with the Institute for Thermal Flowengines at the KIT the behavior of the AMT Titan turbojet, from Dutch producer Draline, was researched, improved and fitted with an exhaust attenuator.
- DG-1000J:also known as 'Akaflieg Karlsruhe AK-9', registered D-KAKJ, named "Jet".
