The bubble canopy of a Lockheed Martin F-22 Raptor Canopy of an F-22 Raptor. An aircraft canopy is the transparent enclosure over the cockpit of some types of aircraft.An aircraft canopy provides a controlled and sometimes pressurized environment for the aircraft's occupants, and allows for a greater field of view over a traditional flight deck.
The canopy and rear fuselage were revised again on the 1957 R-22SV. Early production models, the B-Futár, had a one-piece bubble canopy which allowed an unbroken, deepened fuselage profile back to the fin. Other changes were to the rudder, now with an angled straight tailing edge, and to a new, cantilever tailplane.
The canopy line was lower and smoother than that of the Viking 1. The fuselage narrowed to the rear where the tapered tailplane was mounted just above the fuselage on a short sub-fin or pedestal. The chord of both pedestal and tailplane were greater than on the Viking 1, with more sweep on the tailplane's leading edge .
Differences from the earlier aircraft included a redesigned canopy, retractable monowheel landing gear, and provision for 100 kg (220 lbs) of water ballast. An improved version, the Hornet C was produced in 1979, incorporating a new one-piece canopy originally designed for the Mosquito and an increase in water ballast capacity to 170 kg (375 lb).
The canopy was lengthened and made as a single piece of better aerodynamic form. Twin shoulder release hooks, placed just behind the wing leading edge, were added for Y-end towlines. The modifications added about 50 kg (110 lb) to the empty Orao IIC; the improved aerodynamics raised the glide ratio from about 32:1 to 36:1. [1] [2]
The rear of the canopy was above the fuselage line and a long, ply covered fairing reaching well behind the wing blended it in. A tapered, round tipped and largely fabric covered horizontal tail was mounted on top of the fuselage, far enough forward to place the trailing edges of its elevators at the rudder hinge line.
The DG-101 and DG-101G had improvements such as a single-piece front-hinged canopy, improved crash resistant cockpit and a conventional tailplane (with fixed horizontal stabilizer and articulated elevator). There was also a club version of this sailplane with fixed landing gear. All models featured top-surface-only air brakes.
The fuselage of the ASW 12 was extremely slender for its time. It had a retractable landing gear and a two-piece canopy, of greater depth than was the case with the D-36. Each individual fuselage was manufactured - as with the D-36 - in two halves laid-up on positive mol
