Comment:
The DG-500 comes in a number of sizes which all
share the same basic fuselage. The 500T Elan
Trainer, which first flew in 1989 has an
unflapped 18 m. wing without provision for water
ballast; retractable gear is an option. The
front
cockpit design has been purposely made similar
to
that of the DG-300 Club. The higher performance
versions ( DG-50022 Elan and DG-500 M) have a 22
m. flapped wing and are, respectively, unpowered
and self-launch models. The powered model (DG-
500M) has been liquid cooled Rotax poerplant on
an electrically retracting pylon, digital engine
instrumentation (DEI) and water ballast reduced
to 100 kg. 220 lb. And comes with an optional
steerable nosewheel. The DEI, which has
instrumentation in both cockpits, shows rpm,
temperatures, pressures and fuel quantity as
well
as controlling the amount of fuel injected by
the
electronic fuel system. Engine retraction is
automatic once the propeller has been stopped
and
centered. All 22m. ships, which have a four
piece
wing, have retractable gear as standard.
Performance of the 500M is similar to the 500/22
Elan, but empty and gross weights are 565 kg./
1,246 lb. And 825/1,819 lb. Respectively. A
developed with 3 different sets of wingtips ﾖ
17.2
m. for aerobatics, 18 m. and (with winglets) 20
m. A flapped unpowered development of the DG-
500/22 Elan. Known as the DG-500/20 Elan
Winglets, has been designed for the German 20 m.
two-place contest class. This has the 750 kg/
1,653 lb. Gross weight of the ﾖ500/22, and a
wing
loading of 45.0 kg/sq.m./ 9.22 lb/sq. ft.
Manufacture of the DG-500 is partly by Elan in
Slovenia. |
