Canopy
1. General
The DV 20 E airplane has a one-piece lifting canopy. It has a carbon-fiber reinforced plastic (CFRP)
frame and one large acrylic glass. The canopy glass has two small emergency windows.
The canopy has a hinge at the back and a stabilizing rod on each side. The support arms have
counterbalance springs to help operate the canopy.
A locking system locks the canopy closed. Two latch-levers operate the locking system. One lever is
on the inside of the canopy on the left side. And one lever is on the inside of the canopy on the right
side.
The canopy has a warning light system. The red warning light comes on when the canopy is not
correctly locked. The warning light is on the instrument panel.
2. Description
A. Canopy Structure
Figure 1 shows the canopy. The canopy has a CFRP frame. A one-piece acrylic transparency
attaches to the frame with screws and flexible adhesive. The transparency has two sliding side
windows. The sliding side windows are on each side of the canopy and move in guide rails.
The canopy has a tubular rubber seal. The seal goes round the edge of the canopy frame. When
the canopy is closed the seal touches the cockpit sill.
B. Canopy Hinges
The canopy attaches to the fuselage with three hinges. One hinge at the back of the canopy and
one at each side. A large spring attaches between each side arm and the rear fuselage. The
springs help balance the weight of the canopy.
