What is the purpose of the engine nose cone spinner?
The nose cone (both in terms of strength and angle) is designed to reduced bird impact damage to the engine and reduce ice build-up. The spirals are there as a warning to ground crew when taxiing… In flight, the spirals could not be seen by birds as the rotation of the engine would be too fast.
Why do they put spirals on jet engines?
The primary function of the spiral is to warn the ground crew working around the aircraft that the engine is on and to ensure nobody comes up too close to the running engine. When the engine is running, you will see a white almost transparent blur or a hypnotizing swirl, depending on the rotation speed of the engine.
Why are engine spinners painted?
“Our aerospace engines have swirls painted onto their spinners in order to indicate when the engine is rotating while on the ground. In flight these swirls flicker as the engine rotates at high speed, scaring birds and allowing them to fly clear of the engine.”
Why do white spirals scare birds?
Rolls-Royce has explained in their centenary press release one of the purposes of the spirals in their spinners. “In-flight these swirls flicker as the engine rotates at high speed, scaring birds and allowing them to fly clear of the engine”.
Why are there hooks on the wings of the aircraft?
Each airplane wing is designed to be as smooth as possible to make the aircraft fly efficiently. In the event of a water landing, these small hooks help passengers safely exit the aircraft, one pilot explained in a video.
Why do plane engines open on landing?
Jet engines split open in order to slow down the speed of airplanes when landing. The opening of engines during landing is technically known as a thrust reversal mechanism, and diverts the airflow in the opposite direction. This helps reduce the speed of the airplane, and allows for landings on shorter runways.
What is engine spool?
“Spool” is engineering shorthand for the combination of an engine compressor and high-pressure turbine that drives it using a connecting drive shaft. In a single-spool engine, the high-pressure turbine drives the entire compressor.
What is that yellow thing on airplane wing?
Yellow hooks They’re an anchor for ropes, which passengers use to steady and pull themselves across the wing especially during a water landing. The ropes and hooks can also be used to tether rafts to the plane so they don’t float away as passengers board.
Why are the lights dimmed always during takeoff and landing?
Airlines are today required to turn off plane lights during takeoff and landing. The reason this is done is because of the time it takes for our eyes to adjust to the dark. It can take our eyes between 10 to 30 minutes to adjust to darkness. Therefore, airlines today turn off lights during takeoff and landing.
What was the name of the German plane in WW2?

What was the most popular plane in WW2?
The most-produced aircraft of World War Two. The Messerschmitt Bf 109 formed the backbone of the Luftwaffe’s fighter force, with over 33,000 seeing service on all European fronts. Like the Spitfire, several variants of the Bf 109 were produced during the war to improve its design.
Why was the Heinkel He 111 so important?
The Heinkel He 111 was one of the Luftwaffe’s main medium bombers. First seeing service in Spain, it featured prominently during the early years of World War Two, but soon proved highly-vulnerable to fighter aircraft such as the Spitfire and Hurricane.
Why did Germany use catapults in WW2?
Launched from catapults, they protected Kriegsmarine vessels from the air, chasing away RAF patrol boats. They saw service on famous battleships such as the Bismarck and became the standard aircraft of the German navy throughout the war.
