AIRCRAFT RECOGNITION BASIC (ARB)
Lesson 1 Aircraft Recognition Features
WEFTUS NO - THIS IS A WETDOG
WEFTUS NO THIS IS A WETCAT (AND ANGRY TOO)
Few hints here see if you can identify WETFUS
WEFTUS is an acronym for recognisable features of an aircraft
Wings
Engines (Nacelle)
Tail (Empennage)
Fuselage
Undercarriage
Special features
WINGS - location
WINGS - shape
WINGS - Bracing
WINGS – X Plane
Grumman X29
WINGS – Crescent
Hanley Page Victor long range heavy bomber
WINGS – Stealth Bomber
WINGS – Have other uses
WINGS – When Anhedral becomes dihedral
Boeing B52 Stratofortress
ENGINES
There are 4 types of engine used in aircraft
• Piston – fuel petrol (higher octane than cars use)
• Gas turbine - fuel AVTUR (keroscene) • Rocket• None – gliders
Number and location of engines
Piston engines Radial Engines
Radial engines early models the crankshaft was stationary and the cylinders rotatedLater engines the cylinders were stationary and the crankshaft rotated R 2800 is known as the Prat & Witney Twin Row Wasp it ahs 18 cylinders (45.96 L) producing 2,800 hp (2,100 kW), Diameter: 52.8 in (1,342 mm) for Aircraft such as the DC6 and the Super Constellation
Piston engines V Engines most famous Rolls Royce Merlin
The engine that helped win WWII Length: 88.7 in (225 cm producing 1,290 hp (962 kW)
Piston engines Horizontally opposed
Lycoming & Continental are the major manufacturers
Piston engines Horizontally opposed in aircraft
Gas Turbine engines Commonly Jet engines
• Ram Jet• Pulse• Radial Flow• Axial Flow• Turbo Fan• Turboprop
