1. Answer the questions:

  1. What is combustion?

  2. What can we use as a fuel?

  3. What do we need exhaust for?

  4. W hat is the fundamental difference between the two types of engines?

  5. Where does a jet engine obtain its oxidizer from?

  6. What is the key way the rocket engine differs from the jet engine?

  7. What are three types of fuel for space crafts?

  8. What type of fuel is easier to handle and store and why?

  9. What is a difference between a rocket and a jet engine?

  10. Why are solid rockets safer?

2. Translate the words combinations:

  • the process of combustion

  • an internal combustion engine

  • a high-pressure exhaust

  • external atmosphere

  • own supply of oxygen aboard the vehicle

  • much easier to handle and store

  • are most commonly used

  • until none remains

  • potential booster for high-speed military missiles

  • propulsion system

  • the chief advantage

  • the primary difference

  • calling such a device a "rocket" is a little confusing

  • to produce thrust

3. Translate from Russian into English:

  • горение и окисление

  • вещество, содержащее кислород

  • выхлоп под высоким давлением, создающий движущую силу для ракеты

  • похожее устройство

  • твердотопливные ракеты, которые гораздо легче хранить и перевозить

  • основное преимущество

  • смесь инертна и не подвержена возгоранию в обычных условиях

  • ракета такого класса создавалась с преимуществами ракет обоих типов

  • может двигаться с различной скоростью, регулируя уровень окислителя

  • источник тепла, используемый в качестве искры

4. Say if the sentences are true or false:

  1. Combustion is defined as the burning, or oxidation to produce energy.

  2. A fuel for an internal combustion engine can be only natural gas or oil.

  3. Both the jet engine and the rocket engine combust a mixture of fuel and oxidizer.

  4. The jet pulls in oxidizer from the atmosphere.

  5. A rocket carries its own supply of oxygen aboard the vehicle because it flies in the space where there is no oxygen.

  6. Solid rockets are not typically safer, and they are usually not as powerful or efficient as their liquid cousins.

  7. The ducted rocket is attractive as a potential booster for high-speed military missiles, and many such designs have entered service recently.

  8. A jet engine works in the vacuum space and the rocket operates in the atmosphere.

  9. We can buy liquid rocket motors in a store and use them to launch model rockets.

  10. A liquid fuel and a liquid oxidizer are carried in the same tank.

5. Translate the text.

6. Render the text in Russian according to the plan.

  1. What is combustion and what can we use as a fuel?

  2. What is the main purpose of both jet engine and rocket engine?

  3. What is the main difference between jet engine and rocket engine?

  4. What liquids can be used in liquid rockets?

  5. What is another type of rocket and why is it safer and easier to handle and operate?

  6. What is a hybrid rocket?

  7. What is the technical way to explain the difference between jet and rocket engines?
