A New Regime Reading
After reading the story A New Regime,
answer the questions below using complete sentences.
1. The author compares Yeager and the research team
Explorers of the New World centuries ago.
2. Why do you think the author makes this comparison?
Because these people were exploring new territories just like the explorers
of old and were breaking a barrier (the sound barrier) just like the explorers
broke the barrier of crossing a huge ocean (the Atlantic Ocean).
3. Name the two aircraft that are in this story. Tell
which one is the mothership and which one is the experimental aircraft.
B-29 bomber was the mothership and the X-1 was the experimental aircraft.
4. What were these flight tests trying to accomplish?
They were testing an aircraft and the theories they had about supersonic
flight to see if an aircraft could safely fly at supersonic speeds.
5. As the aircraft flew closer to supersonic speed what
did Yeager's aircraft experience?
The aircraft was buffeted by pressure waves.
6. Give the date that officially marks the beginning
of supersonic flight.
October 14, 1947 officially marks the beginning of supersonic flight.
7. Describe what happens aeronautically to an aircraft
as flies through the transonic regime into the supersonic regime.
At Mach 1 or during transonic flight, the aircraft actually catches
up with its own pressure waves. These pressure waves turn into one big shock
wave that buffets the aircraft. The shock wave also creates high drag on
the aircraft and slows the aircraft's speed. As the aircraft passes through
the shock wave it is moving faster than the sound it makes. The shock wave
forms an invisible cone shape. When the shock wave hits the ground it causes
a sonic boom.
8. What causes a sonic boom?
Pressure waves turn into one big shock wave that buffets the aircraft.
The shock wave also creates high drag on the aircraft and slows the aircraft'9s
speed. As the aircraft passes through the shock wave it is moving faster
than the sound it makes. The shock wave forms an invisible cone shape. When
the shock wave hits the ground it causes a sonic boom.
9. From what was the X-1's shape modeled?
The X-1 got its shape from a .50 caliber machine gun bullet.
10.Why did the aeronautical engineers use thin, straight
wings on the X-1?
Thin, straight wings lower the amount of drag the aircraft would encounter
at transonic speed.
11.How did they improve the pilot's ability to control
the X-1 during flight?
Engineers and researchers designed a new tail section that improved
the ability of the stabilizer and the elevator to control the aircraft.
12.What does the author compare Yeager's X-1 flight to
as it flies from the transonic speed through the supersonic speed?
The author compares the flight to riding a bucking bronco that turns
into a loping Arabian. The flight goes from a rough ride to a smooth ride.
13.What speed did the X-1 reach on this historic flight?
The X-1reached the speed of 1.07 Mach or about 700 miles per hour.
14. What did this flight prove?
This flight proved that flying at supersonic speeds could be safely
