Video answers: ‘GE’s bet on goliath engines’

Here are the answers to last Friday’s video, enjoy!

Suggested ICAO level for video: 5+

  1. The GE9X was selected to power the new 777X aircraft.
  2. They loosened the regulations related to twin-engine aircraft operations, making it possible for airlines to start using them on their long-haul flights.
  3. He had to decide whether to build a derivative of the CF6 engine, which was cheaper, or spend more than $2 billion on a completely new engine.
  4. Its most impressive improvement was the enormous increase in the high pressure compressor capability, which allowed the engines to set a world record for thrust.
  5. It will be lighter, more durable, will have a larger fan, a higher pressure ratio, and a 10% improved fuel burn over the GE90.

GE’s Big Bet on Goliath Engines

In 1990, Brian Rowe bet $2 billion on a revolutionary jet engine design that would go on to influence three decades of propulsion. The GE90’s concept, architecture and technologies allowed for extraordinary gains in the aviation industry, culminating in the new GE9X engine for the Boeing 777X.

Video answers: ‘How does an engine work?’

Here are the answers to last Friday’s video, enjoy!

Suggested ICAO level for video: 5+

  1. Air is pulled into the engine and is pushed out the back at a great speed.
  2. It’s an engine where the majority of the air sucked into it doesn’t pass through the compressor, combustor or turbines, but passes these parts to be ejected directly into the exhaust stream.
  3. It uses less fuel and is therefore more efficient.
  4. They turn the turbines and its shaft, which drives the compressor and fan.
  5. In truth, it’s team work, the air that passes through the engine provides the energy to drive the engine, and the air that bypasses the engine provides most of the thrust to move the plane forward. But neither could exist without the other.

  1. In it’s most basic form, how does the engine produce thrust, according to the video?
  2. What is a high bypass engine?
  3. What advantage does this engine have over others in relation to fuel efficiency?
  4. What do the hot gases do after they leave the combustion chamber?
  5. According to the video, which does most of the work, the air that bypasses the engine, or the air that passes through the compressor, combustor and turbines?

How does an engine work

We don’t even think twice any more about taking an airplane to get from one place to another, but do you know what it takes to power an airplane? Plunge into the incredible world of jet engines and see how they work.

Audio answer: ‘Don’t forget the doors!!’

Here’s the text to the listening from yesterday.

Enjoy!!

An Airbus was climbing to its cruise level when a passenger noticed something strange about the left engine. The fan cowl door was open and seconds after the passengers noticed this, the door separated from the engine. The same thing happened to the other engine also. This engine, the right one, was also damaged during the fan cowl door separation and fuel started to leak. The passenger alerted the flight attendant who told the pilots. They immediately cancelled their climb and initiated a descent to return to their airport of origin. Fortunately there was no fire, the plane landed safely and the engine with the fuel leak was shut down. The passengers disembarked and took another flight 90 minutes later.
