Why are engine cowlings flat on the bottom? Why is the engine bottom flat? … This would prevent the engines from hitting the ground, even if they were larger than previous models. Subsequently, the engines on future 737s were flattened along the bottom. This allowed them to contain a larger fan and turbine without compromising on ground clearance.
Why are jet engines below the wing? The function of jet engines is to produce thrust which pushes the aircraft against the surrounding air. So, for a given amount of thrust, The lift produced is also a function of wing profile and wing are. So, to make best use of wings area available, The engines are suspended below the wings. This is the main reason.
Why do jet engines have swirls on them? 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.
How many engines does a 737 have? The 737-800 is the most common 737NG variant. The Boeing 737 Next Generation, commonly abbreviated as 737NG, or 737 Next Gen, is a narrow-body aircraft powered by two jet engines and produced by Boeing Commercial Airplanes.

Mechanical Systems Engineering is a blend of mechanical engineering, computer-aided engineering, control engineering, systems design engineering and electronic engineering in order to design and manufacture useful products.
How is geometry used in electrical engineering?
Geometry is also used whenever electricians draw up blueprints or building plans. Creating scale representations of any structure requires the understanding of geometry principles and applications. These plans may need to be used by an entire electrical team as well as other contractors, so accuracy is essential.
What does a blown engine sound like?
You’ll know your motor has blown if there is a very loud noise. It can sound like a bang or a very loud knocking noise. If the engine is completely seized or you see smoke billowing out, that’s also a sign that it’s blown.
What are the requirements for turbine engine lubricants?

Do you have to warm up a diesel engine?
The only warm up time you really need is about 30 seconds, just to get the oil circulating. In fact, diesels won’t reach operating temperature unless they’re under load, so warming an engine up prior to driving is actually just prolonging the process.
What does a turbo do in a diesel engine?
