Chapter 7 – Basic Aeronautics and Aerodynamics
Today’s Mission Requirements Discuss the layers of the atmosphere, its composition and height. Describe the atmospheric properties of pressure, temperature, and density EQ: Explain the basics of aeronautics and aerodynamics.
Airdynamics
The Realm of Flight The science of aerodynamics involves the study of airflow around an aircraft, passage of air through a jet engine and even the thrust of energy from a rocket motor.
The Realm of Flight The layers of the atmosphere: Troposphere, stratosphere, mesosphere, thermosphere, and exosphere The atmosphere is a mixture of gases 79% nitrogen 21% oxygen 1% of other gases The atmosphere extends to about 100 miles (approx. 528,000 ft)
Pressure Top layer of atmosphere has less pressure Pressure is greatest at Earth’s surface Pressure decreases with increase in altitude “Standard Pressure” is 14.7 psi or 29.92 inches
Temperature Temperature is a measure of energy The hotter the air, the more energy it has inside and the faster the molecules move around. Temperature decreases approx 3 ½ degrees for every 1,000 ft increase in altitude Decrease occurs up to about 38,000 ft
Density Density of air means how many molecules are squeezed into a given volume. Higher density air is squeezed more tightly than lower density air. Cool day at sea level, air is dense – aircraft perform very well.
Density Air at higher altitudes has less pressure – it is also less dense. Density is also related to temperature. As air is heated, the molecules move farther apart Which means there is a decrease in density On a hot day, aircraft in high altitudes have difficulty taking off – air is too thin
