Based on the needs of British European Airways for a hundred seat turboprop aircraft Vickers designed the Vanguard. The Viscount was taken as starting point, so both aircraft have the same basic characteristics, such as the configuration, horizontal stabilisers with dihedral and oval cabin windows. The engines are in the wing's leading edge. The engine nacelles are slender, and have circular air intakes around the prop spinners, typical for the Rolls Royce Tynes. The vertical stabiliser has a trapezium shape with a dorsal fin in front. Typical for the Vanguard is the streamlined nose and cockpit with many windows. The fuselage has a double double cross section.
The nose and cockpit of the Vickers Vanguard are quite streamlined, as are the many cockpit windows. From this angle the nacelles with ring shaped intakes are well visible. (photo Steve Fitzgerald/WikiMedia)
From this angle the Vanguards tail is better visible: the horizontal stabilisers have a significant dihedral and the vertical stabiliser is a trapezium with dorsal fin. (photo Rob Hodgkins/WikiMedia)
The different versions of the Vickers Vanguard can externally be distinguish by
- the shape of the dorsal fin
- the presence of a cargo door in the left forward fuselage
Details will be added later.
Confusion possible with
The Vanguard was the successor of the Viscount. The Viscount also has oval cabin windows and stabilisers with dihedral. The nacelles have ring shaped air intakes as well. Contrary to the Vanguard it has a less streamlined nose and with the cockpit popping out. The vertical stabiliser is curved from dorsal fin to the back.
The Soviet counterpart of the Electra and Vanguard can best be recognised by the round cabin windows and four wheels on the main landing gear, apart from other differences. The fuselage is round.
The Lockheed Electra has a curved vertical stabiliser like the Viscount, so different from the Vanguard. Furthermore the Electra has a circular fuselage, rounded nose, rectangular cabin windows and nacelles above the wings with intakes at the top.
The Orion is a maritime patrol aircraft derived from the Electra, which is clearly visible in the curved vertical stabiliser, wings and nacelles above the wings with intakes at the top. So these are also the way to distinguish it from the Vanguard.
