The foundation connecting the aircraft engine to the main body is the engine mount. This connects the engine to the fuselage, suppresses engine vibrations, and distributes them to the whole aircraft safely to allow a smooth flight. An engine mount is made with precision with a sturdy metal body to balance the weight of the engine to match various torque requirements. The mount has a web shape with high endurance and a lot of strength despite being simple to look at.
The main materials for making engine mounts include Chromoly tubular steel and steel chrome molybdenum. Despite having similar materials, aircrafts have different engine capacities, dimensions, and dynamics. So, mounts are built to match a particular aircraft making them have different sizes and shapes regardless of having similar material and compositions.
Features of a Quality Engine mounting
An engine mount is an essential feature in an aircraft. The mount is a metal frame surrounding the aircraft’s engine to keep it steady and firm in place. A mount bears the weight of the aircraft engine. There are various types of engine mounts as you are going to discover below but each has particular features. Understanding the features below allows selecting the right mount to match your aircraft’s requirements.
The ideal engine mount should have enough strength to handle turbulence, high speed, and harsh elements throughout its lifespan. A stronger engine mount will last longer. This is made from strong material that withstands all challenges that come while the aircraft is flying in the air. It is important to understand the aircraft engine overhaul cost to ensure that it covers a strong and durable mount.
The ideal material for the engine mount should be robust and durable. The strength and robustness of the mount determine how long it will last. The material for constructing the engine mount plays a significant role in determining its lifespan. When in the market, the rule of thumb is to invest in a durable engine mount with long-lasting material.
The shape matters when searching a mount for your aircraft. An engine mount should have a perfect shape to snugly fit where it is needed to perform desired functions. Investing in a mount with the right shape for the engine ensures proper functioning. Keep in mind that aircraft engines have different shapes and require a fitting mount to keep the engine safe and firm. The ideal engine mount should match the engine shape and aircraft model.
Precise Joints and Bends
An engine mount should have precise joints and bends matching particular spaces, curves, and gaps between the engine component and overall shape. A mount with the right joints and bends fits perfectly into place. Besides, the preciseness allows fixing the mount accurately to give the engine due firmness and strength. Any slight imperfection on the mount will make it not fit properly. Apart from accuracy and precision, the strength of the bends matters.
The engine mount should have proper placement of all the nuts and bolts. A mount that fits snugly ensures the safety of the engine and aircraft. It also guarantees a comfortable and stable flight since the aircraft faces little vibration.
A perfectly fitting mount ensures no noise comes from the engine. A poorly fitting mount compromises the safety of the aircraft. It comes with a risk of regular vibration and turbulence throughout the flight. And, the mount will require regular repair throughout its lifespan.
Types of Aircraft Engine mounts
Conical Engine mounts
These are the simplest engine mounts for their easy maintenance and installation. Conical mounts have four points for connecting the engine for a sturdier grip. Unfortunately, this type of mounts lacks effectiveness for high-power engine vibrations. Conical engine mounts are usually for traditional aircrafts and smaller ones. Additionally, passenger aircrafts also use conical mounts for matching their maintenance and repair processes.
Dynafocal Engine mounts
Stronger than conical mounts, dynafocal mounts suppress engine vibrations while maintaining the flow of force resulting from torque. The design of these mounts is based on gravity points in aircrafts that vary from plane to plane. Dynafocal mounts have a ring shape for better structural strength. However, this limits access when making repairs and during installation. These engine mounts are costly making them ideal for commercial aircrafts.
This type of engine mount is for Rotax and diesel engines and comes with special features. The bed mount has a shape with a diverging effect of conical and dynafocal mounts. Installing the aircraft engine is above the mount to resonate with the name of this mount.
Bed engine mounts have better engine connectivity and structural strength. This mount is installed under the crankcase becoming the biggest difference from the other types of mounts. A bed mount has four fastening points for secure engine stabilization.
Engine mounts are very important features in an aircraft. The mount keeps the engine securely in place and limits vibrations during flight. When doing an aircraft engine overhaul, replacing or repairing the engine mount requires professional assistance.
