AIRCRAFT AND ITS PARTS CAPT. STANISLAV HOFMAN UO BRNO 2015

Aircraft dividing Lightier than air - is characterized by one or more large gasbags, - filled with a low-density gas such as helium, hydrogen or hot air - Hot-air balloons - Airship (zeppelin) Heavier than air - need to produce aerodynamical force for their motion in the air - Airplanes - fixed wing aircraft - Helicopter, Chopper - with rotor

Aerodynamic forces

Thrust- create by power of engine Drag- depends on airplane shape, resists against motion Lift- create due to pressure balance on the wing Weight- caused by gravity

Aircraft purpose Trainer Transport aircraft Combat – tanker, bomber, military helicopter, fighter Medical – helicopter Sport – ultralight, glider, paraglide Speeds of aircraft Subsonic IAS<1 Mach level Transonic IAS = 1 Mach level Supersonic.... IAS>1 Mach level Hypersonic….IAS>5 Mach level

Example of military purpose FIGHTER – used to fight other aircraft in the air BOMBER – drops bombs GROUND ATTACK – attacks targets on the ground TRANSPORT– used to carry large quantities of supplies or people TRAINER – to learn student pilots to fly TANKER – used to refuel other aircraft in the air HELICOPTER– a vertical take-off aircraft, ground support

High-wing, mid-wing, low-wing aircraft Single, twin, triple or multiple - engined aircraft Monoplane, biplane, triplane etc.

1) Wings Designed to generate lift Starboard wing/port wing Leading edge/ trailing edge Control surfaces - WINGS-Ailerons - VERT.STAB.-Rudder - HORIZ.STAB.-Elevators

2) Fuselage Cockpit,windshield Portholes Passenger cabin Cargo (baggage) compartment Seats, overhead compartment Toilets, galley,wardrobe Technical compartment Empennage, tail unit Exits

3) Power unit Turboprop engine Jet engine

3) Power unit On the wings On the wing pylons Rear mounted Close to the fuselage

4) Landing gear Fixed/retractable Nose gear Right and left main gear Tail wheel undercarriage bay undercarriage door undercarriage leg tires Retracting mechanism Shock absorbers

5) Control surfaces
