Chile eruption: How volcanic ash stops a jet engine

The video explains how abrasive particles can erode parts of an aircraft, particularly affecting jet engines. It describes the high temperatures in jet engines and how glass particles can melt and adhere to turbine blades, potentially causing engine stalls. The video also outlines a cooling process that allows engines to be restarted by cracking and dispersing the molten glass.

Which part of the aircraft is most vulnerable to damage from abrasive particles?

• The landing gear

• The engine

• The tail

• The fuselage

At what temperature does the hottest part of a jet engine operate?

• 1800 degrees Celsius

• 1500 degrees Celsius

• 1200 degrees Celsius

• 1000 degrees Celsius

What happens to glass particles when they pass through the combustion chamber of a jet engine?

• They evaporate

• They turn into ash

• They solidify

• They melt and stick to turbine blades

What is the purpose of turning off the engines when dealing with molten glass?

• To save fuel

• To allow cool air to pass through and crack the glass

• To reduce noise

• To prevent overheating

How does the cooling process help in restarting the engine?

• It refuels the engine

• It repairs the turbine blades

• It disperses the molten glass

• It increases engine speed
