Lent term test Flashcards
1
Q
Leonardo Da Vinci
A
1452-1519
Italian artist and inventor
Produced many aircraft designs resembling flapping wings
Never built designs, wings were too heavy to operate
2
Q
Montgolfier Brothers
A
- Built a hot air balloon in 1783
- Late 1783 saw first living creatures to be artificially airborne
- 1783 also gave first free flight
- Hydrogen filled balloon by J Charles superseded the Montgolfier balloon
3
Q
Why balloons fly
A
- Displaces own volume of air causing upthrust
- Hydrogen and helium are less dense than air
- Balloon ascends, atmospheric pressure falls and balloon expands
- Gas is released or expands in spare envelope space
4
Q
Airships
A
- Large air crafts filled with hydrogen
- Able to carry lots of cargo and people
- Extremely dangerous
- 1937- Hindenburg incident
- Airships no longer used as much
5
Q
How airships are controlled
A
- Two ballonets in the main balloon
- Ballonets maintain pressure in balloon
- Prevents balloon overinflating or sagging
- Ballonets release air to ascend
- Air pumped into ballonets to descend
6
Q
Sir George Cayley
A
- Built first model glider- 1804
- It was a broomstick with a kite shaped wing at one end and vertical and horizontal tail surfaces at the other attached
- It was capable of stable flight over many metres
- Confirmed heavier-than-air flight was possible
7
Q
Hand-gliding
A
- Failure to develop light enough engine for flight
- Instead focus was put on improving airframe design
- Otto Lilienthal - built lightweight gliders
- Made many thousands of flights
- Built so mass could be moved for some control
8
Q
Wright brothers
A
- 1903- Orville and Wilbur Wright’s ‘Flyer’ had first test flight
- First time man was airborne and in control of a powered heavier-than-air flight
- By end of 1908, Wilbur Wright made over 100 flights
- Orville Wright demonstrated the Flyer to the public
9
Q
Louis Bleriot
A
- 1909- crosses the English Channel by heavier-than-air craft
- Bleriot’s aircrafts were also the first:
- Over the Alps (1910)
- Non-stop trop from London to Paris (1911)
- Airmail carriage in Britain (1911)
- Use of aeroplane in war (1911)
10
Q
WW1
A
- War increased development of aeroplanes and engines
- Development of more sophisticated gun technology
- The SE5a - one of the most popular British fighters
- Bombing was limited with little military effect
11
Q
Post- WW1
A
- 1919- converted Vickers Vimy bomber made first non-stop crossing of the Atlantic by Alcock and Brown
- 1930 - Amy Johnson made first solo flight from England to Australia in a Gipsy Moth
- The Tiger Moth- the Royal Air Force’s trainer in the World War Two
12
Q
WW2
A
- 1939- war caused further technological development in aircrafts
- 1944- Germany launched the V-1 (‘Doodle Bug’ or ‘Flying Bomb’)
- Gloster Meteor entered service one month later to destroy V-1s
- Germany used rocket-powered Messerschmitt Komet fighters to intercept enemy bombers
13
Q
Jets
A
- Jets inspired ideas such as jet passenger services, supersonic flight, and vertical take-off and landing
- World’s first jet airliner- de Havilland Comet 1
- Pressurised cabin allowed for flight in all weather conditions
- Most successful aircraft of jet airliners was the Boeing 707
14
Q
Concorder and Boeing
A
- Concorde was supersonic transport- flew at twice the speed of sound
- Only served two airlines, British Airways and Air France
- Retired in 2003
- Boeing planned for a huge airliner with 400 seats
- 747 made international travel an almost commonplace experience
15
Q
Before the RAF
A
- The first Air Force was the Royal Balloon School
- 13th March 1912: Royal Flying Corps is formed
- July 1914: Navy Wing splits and forms Royal Naval Air Service
