AE 550 – thermodynamics-mini Report


Air density at sea level and 15 0C is 1.225 kg/m3. As altitude increases the air density reduces and at just over 20.000ft the air density is half that at sea level. When at 60,000ft it is 10% of that at sea level.

An aircraft engine uses air (oxygen) for combustion. Jet engines compress air to mix with oxygen and produce a combustible substance to create the energy needed. As air (oxygen) reduces more compressed air is needed.

Explain, in thermodynamic terms what happens and how it is achieved to ensure that an engine can operate at altitude for commercial aircraft. What changes, differences in design for engines, are required for aircraft that operate at higher altitudes?
