TYPE OF PLANE

Passenger -- The mass of a large number of passengers need  the plane to carry an excessive amount of weight; a strong structural form is needed
Cargo - Smaller, faster. Weight is less of a concern.
International -- Travelling in further distance will require longer flights; engines must be capable of withstanding within the air

"high-pressure turbine blades operate in an environment where temperatures can exceed 1,700 degrees Celsius. This level of heat is above their melting point, so each blade has tiny air holes drilled in it where “cooling air” of around 700 degrees Celsius is blown to cover the blade’s surface. This increases the durability of our engines"

Design an ethical aircraft that utilises electricity.
Think about:
How it would take off and land
The environmental impact including power and noise pollution
How the engine will differ from a tractional propulsion system
