AERO 310 MidTerm Exam Study Guide 1. What were early (~200AD) Chinese unmanned hot air balloons called? Airborne Kongming lanterns 2. What was the Chinese hot air balloons originally made from? waxed rice paper and bamboo frame with small candle 3. What was the oldest successful humancarrying flight vehicle? hot air balloon 4. How does a hot air balloon stay in the air? hot air is less dense than cool air= buoyancy (hot air rises) 5. What is the difference between an airship and an aerostat? aerostat is a moored balloon airship leaves the ground completely and can be steered and propelled by its own power 6. What are the evolving lifting gas technologies? hot air hydrogen hot air and hydrogen helium helium and aerodynamic lift 7. Which gas, other than hot air, first filled a humancarrying air vehicle? hydrogen 8. What are the three types of structural arrangements for airships? rigid, semirigid, and nonrigid 9.

Why did the Wright Brothers succeed, when all others failed? 1. single focus 2. repaired and built bicycles= influenced thinking that an unstable vehicle could be balanced and controlled with practice 3. handson doers 4. talked everything through 5. windtunnel testing= tested over 200 wings 6. modified wind pressure tables 7. light internalcombustion engine 8. wing warping for roll control 31.
