Aircraft and their parts

Type of aircraft �Heavier - than - air, they must have a power source to provide thrust necessary to obtain lift �Lighter - than - air, filled by gases lighter than air, providing necessary lift.

Aircraft �Aircraft 1. Airplane - with fixed wing 2. Helicopter - with rotor

Forces act on aircraft �Thrust - produced by engine, necessary forward motion �Drag - acts against thrust, resists against motion �Lift - necessary for flight, keeps aircraft in the air, produced by wing �Weight - caused by gravity

Aircraft structure � Propeller high - wing single aircraft � High-wing, mid-wing, low-wing aircraft � Single, twin, triple or multiple - engined aircraft � Monoplane, biplane, triplane etc.

Jet combat aircraft

�Trainee �Transport aircraft �Fighter �Bomber Subsonic. . . IAS<1 Mach Transonic. . . IAS = 1 Mach Supersonic. . . IAS>1 Mach

Twin-engined mid-wing airliner

Definitions � Propeller - device driven by engine providing necessary thrust � Wing - is mounted on bough side of airplane, produces lift � Aileron - control surface on trailing edge of wing for banking � Flap - device on inner trailing edge increasing lift during landing, approach and take-off � Fuselage - body of aircraft which connect each part � Landing gear - undercarriage - device for motion on ground

� � � � � Elevator - control surface necessary for climbing or descent Rudder - control surface on trailing edge of fin for yawing Fin - one part of tail unit (empennage) Horizontal stabilizer - second part of empennage Cabin - compartment for pilots and crew Cockpit - where pilots sit Ejection seat - special seat with parachute and rocket engine for saving pilot life Cannopy - device covering cockpit Radome - front part of aircraft protect aircraft radar. Engine - providing thrust 1. Piston - with cylinders 2. Jet 3. Turboprop - when propeller is driven by turbine

Flight deck - cabin for pilot, pilot compartment � Galley - special compartement where meals are prepared � Passanger cabin � Wing rib � Spar � Engine mounting pylon - carries power unit under wing � Leading edge - front side of wing � Trailing edge - rear side of wing �

Cockpit Instruments

� Control stick - connected with control surfaces for control of airplane � Control pedals - connected by rudder � Radio �Transmiter - for sending information �Receiver - for receiving information � Fuel gauge - shows amount of fuel � Artificial horizont - shows atitude, indicates banking or rolling

Helicopter parts �Combat helicopter

Glossary � � � � Airliner - dopravní letadlo Act - působit Aircraft - letadlo Airplane - letoun Drag - odpor Lift - vztlak Thrust - tah Weight - tíha Aileron - křidélko Elevator - vyškové kormidlo Rudder - směrové kormidlo Fin - kýlová plocha Vertical stabilizer - Svislá stabilizační plocha Horizontal stabilizer - Vodorovná stabilizační plocha Fuselage - trup
