McDonnell Douglas Engine Parts

Finding the right engine parts for your McDonnell Douglas plane or helicopter is important. Here are some common questions that may come up when youre searching for McDonnell Douglas Engine parts.

What aircraft types does McDonnell Douglas make?

McDonnell Douglas is an aerospace company that makes a variety of different aircraft styles for airlines and other end users. These include:

  • Small personal airplanes and small commuter planes
  • Military jets
  • Private personal jets
  • Helicopters
  • Large commercial airliners
  • Cargo planes
  • Experimental aircraft types
  • Manned spacecrafts
What are some components of McDonnell Douglas airplane engines?

An aircraft is traditionally propelled by one of two engine types: piston-driven combustion engines or jet engines. Piston-driven engines work in a similar way to a piston-driven combustion engine and are common on smaller planes. The McDonnell Douglas DC7 was the last combustion-driven commercial airliner in production during the time before jet-engine technology took over. McDonnell Douglas piston-driven engines have several components, including:

  • Camshafts, crankshafts, and crankcases: A camshaft is a spinning shaft that opens the valves as the cams go by. Crankshafts convert motion thats directed up and down into a spinning motion, which can drive a propeller. Crankcases hold the crankshaft.
  • Fuel pumps: Fuel pumps deliver measured amounts of fuel to a combustion engine.
  • Gaskets: These are rubber seals that connect two engine components in a way that keeps gases or liquids inside. They can help prevent metal-on-metal wear.
  • Gears: Gears are notched disks that connect to each other in a way that allows them to spin in tandem. As gears change in size, they allow for different mechanical advantages.
  • Vernatherms: These are temperature-controlled valves that control the flow of oil into oil coolers.
  • Lifters: Lifters work the intake and exhaust valves.
  • Rods, rod bolts, and bearings: These are the parts that connect pistons to crankshafts.
What components are in McDonnell Douglas jet engines?

A jet engine is often employed in aircraft thats intended for cross-country and transoceanic flights. Its components are contained in two sections: a hot section and a cold section.

The cold section is the intake section. Its purpose is to take in large amounts of air. A subsonic intake is in the shape of a duct that regulates the amount of air coming in at high speeds. Air then goes to the compressor or fan, which is a series of spinning blades and statutory vanes. Shafts then take the air to the compressor.

The hot section is the combustion chamber where air is mixed with fuel. The hot gases then drive the compressor and spin the turbine rotor. The turbine helps speed the gas as it is expelled through the exhaust in a jet blast. That process allow for ultra-high speeds.
