Question 2: ________ obtain little thrust from jet effect, but are useful for comparison.
TurbojetTurboshaftTurbopropTurbofan

Question 3: Relentless improvements in the turboprop pushed the piston engine (an internal combustion engine) out of the mainstream entirely, leaving it serving only the smallest general aviation designs and some use in ________.

Question 5: Each engine manufacturer will pick between those two abbreviation but N1 is mainly used for ________ engines whereas Ng is mainly used for turboprop or turboshaft engines.

Question 6: What does the following picture show?

  The Whittle W.2/700 engine flew in the Gloster E.28/39, the first British aircraft to fly with a turbojet engine, and the Gloster Meteor
  Schematic diagram illustrating the operation of a low-bypass turbofan engine.
  Comparative suitability for (left to right) turboshaft, low bypass and turbojet to fly at 10 km altitude in various speeds. Horizontal axis - speed, m/s. Vertical axis displays engine efficiency.
  Simulation of a low bypass turbofan's airflow

Question 7: The ________ was not an idea developed in the 1930s: the patent for a stationary turbine was granted to John Barber in England in 1791.
Diesel engineInternal combustion engineGas turbinePower-to-weight ratio

Question 8: What does the following picture show?

  Specific impulse as a function of speed for different jet types with kerosene fuel (hydrogen Isp would be about twice as high). Although efficiency plummets with speed, greater distances are covered, it turns out that efficiency per unit distance (per km or mile) is roughly independent of speed for jet engines as a group; however airframes become inefficient at supersonic speeds
  The Whittle W.2/700 engine flew in the Gloster E.28/39, the first British aircraft to fly with a turbojet engine, and the Gloster Meteor
  A schematic of a ramjet engine. "M" in the image refers to the Mach number of the airflow.
  Comparative suitability for (left to right) turboshaft, low bypass and turbojet to fly at 10 km altitude in various speeds. Horizontal axis - speed, m/s. Vertical axis displays engine efficiency.

Question 9: ________ accelerate a much smaller mass of the air and burned fuel, but they emit it at the much higher speeds possible with a de Laval nozzle.
TurboshaftTurbopropTurbofanTurbojet

Question 10: Some scientists believe that jet engines are also a source of ________ due to the water vapour in the exhaust causing cloud formations.
Ozone depletionGlobal warming controversyGlobal dimmingOcean acidification
