High-Precision Aircraft Components: Engines, Wings & More

Engine

Precision aircraft parts and components can also be described as the powerplant of the plane. It is the part of the plane that generates thrust to lift the plane into the sky. The engine also produces hydraulic and electrical energy that the aircraft uses to operate.

 

The Wing

Airplane wings are their most recognizable parts and precision parts of an airplane. These wings act like the wings of a bird, lifting the plane into the air and controlling airflow during flight. Wing pitch is a key part of the overall airplane design as it allows the pilot to decrease or increase the descent speed of the airplane during flight. It's a big deal when a wing gets damaged, and it's one of the reasons planes are usually kept in hangars when not in use - but hangar construction can be in itself.

 

Quill

Ailerons are the hinged surfaces of the wings that help to control lateral balance. They work to move the plane left or right, allowing it to roll in the desired direction. The ailerons work asymmetrically during flight. This means that when the right aileron goes up, the left aileron goes down. When the right side goes down, the left aileron goes up.

 

Strips

The slats are identified as the most forward part of the sash. They are adjustable so that the pilot can adjust the rail to the desired level while lifting the entire plane.

 

Horizontal Stabilizer

A horizontal wing-like structure protrudes at the tail of the plane. These are horizontal stabilizers that help keep the plane in balance during up and down flight.

 

Vertical Stabilizer

In the back of the plane, you'll notice a shark-like fin. This is called a vertical stabilizer. This helps to prevent lateral movement of the craft that could easily lead to a skid, rendering the aircraft uncontrollable.

 

Pylon

Pylons are located on the wings of an airplane between the wing and the engine. Its main task is to help stabilize the airflow behind the wing. Without pylons, the drag on the wing will reduce the aircraft’s speed and overall performance.

 

Flap

Rear flap wings are attached to help increase the plane's lift into the air. These flaps are fitted to follow the edges of the side sections. These flaps protrude from the wing and increase the deflection of the wing profile, allowing it to float at low speeds which is essential for a successful landing.

 

Propeller

Most planes have at least one propeller that pushes the plane forward in a certain pitch, depending on the angle of the propeller blades. On smaller ships, you'll see large propeller blades in the front. In the case of commercial units, they are usually integrated into the wings of the aircraft.

 

Spoilers

The aircraft spoilers are located on the top of the wing and can be extended upwards to reduce airflow. The whole concept of the spoiler is to intentionally reduce the lift of the plane so that it can land properly.

 

Elevator

The elevators work to control the ship's pitch movement. They are hinged surfaces that are mounted on the back of the horizontal stabilizers. They act as a symmetrical pair. When the elevators go up, the plane goes up. When the elevators go down, the plane goes down.

 

Fuselage

It is the most central component of an airplane responsible for the structural integrity of cargo and passengers. Most modern aircraft can carry up to 800 passengers and approximately 250,000 pounds of cargo.

 

Rudder

The rudder is responsible for controlling the yaw of the aircraft. It is a side-to-side movement of the ship's bow. You'll find the rudder as the hinged part on the back of the plane's vertical stabilizer.

While CFRP is the lion's share of precision aerospace parts, the composite material in both the cockpit and functional components, and honeycomb materials provide effective and lightweight internal structural components, next-generation materials include ceramic matrix composites (CMCs) that come into practical use after decades of testing. CMCs consist of a ceramic matrix reinforced with a refractory fiber such as silicon carbide (SiC) fiber. They offer low density / weight, high hardness and most importantly, excellent thermal and chemical resistance. Like CFRP, they can be formed into specific shapes without additional machining, making them ideal for internal aero engine components, exhaust systems, and other "hot zone" structures - even replacing the latest HRSA metals mentioned earlier.

 

The New Materials Relate to the New Aviation Reality

Both metallic and composite materials continue to be developed and improved to offer ever greater performance, whether it be lighter weight, higher strength or better heat and corrosion resistance. Accelerate this evolution of new materials, progress in machining and cutting technology give manufacturers unprecedented access to materials previously deemed impractical or too difficult to machine. New material adoption is happening exceptionally quickly in aerospace, requiring DFM-minded interaction between material characteristics and component design. The two must be in balance, and one can’t really exist outside of the context of the other.

Meanwhile, one-piece designs continue to reduce the number of components across entire assemblies. Overall, this bodes well for aerospace composites that can be formed rather than machined. A variation of this trend occurs in metal structures as more components are conditioned in the forgings to get a near net shape which reduces the amount of machining. Elephant skin, rugged shapes and thin floor sections reduce material costs and the total number of components, but setup and fixation remain a challenge. Some manufacturers are turning to waterjet and other technologies to reduce or eliminate raw materials for disposal. Difficulties still exist in clamping, surface finish, and CAM toolpaths. However, designers, mechanics, engineers and machine tool / cutting tool partners are developing new solutions to keep the evolution moving.

The blend of materials used in the aerospace industry will continue to change with new composites in the coming years metals suitable for machining and new metals increasingly occupying the space of traditional materials. The industry continues to strive for lighter components, increased strength, and greater resistance to heat and corrosion. The number of components will decrease in favor of stronger, mesh-like shapes, and the design will continue to work closely with the material characteristics. Machine builders and cutting tool manufacturers will continue to develop tools to make currently unprofitable materials workable and even practical. All in the name of lowering aviation production costs, improving fuel economy through efficiency and lightness, and making air travel a more cost-effective mode of transportation.
