Fig: Types of Aircraft
Types of aircraft:
1. Lighter than air:
(i) Airship
(ii) Free Ballon
(iii) Captive Ballon
2. Heavier than air
(i) Power Driven
(ii) Non-power Driven
(a) Sailplane
(b) glider
(c) Kites
(iii) Man Power Driven
Power Driven Aircrafts: There are mainly 3 types of power-driven aircraft. These are,
(1) Aeroplane
(2) Rotorcraft
(i) Helicopter (Rotor Powered)
(ii) Gyroplane ( Rotor not Powered)
(iii) Cyclogyro (Paddlewheel type rotor)
(3) Ornithopter
Aeroplane: We can divide aeroplanes into 3 parts mainly. Those are,
(i) Land Plane
(ii) Seaplane
(a) Float
(b) flying
(iii) Amphibian
Spacecraft: A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo.
Ways to fly:
1. Lighter than air
2. Pushing fire downward
3. Pushing air downward
