Aerospace Manufacturing with Linear Actuators
Posted on February 21, 2020 by Anna
Linear actuators are indispensable in the aerospace industry. They are used in absolutely all systems of a space ship or an aircraft. Their usability, durability, easiness to manage and maintain are the main reasons why they are so popular.
What Are Spaceships Made of?Aerospace manufacturing is a special field. When building an aircraft, engineers consider many factors such as vacuum, high pressure, space radiation to name a few; spacecraft materials are of primary importance.
To withstand unfavorable conditions in space, new lightweight alloys and materials are used. Nowadays, the most frequently used materials are:
- • Vanadium
- • Titanium
- • Advanced composite alloys
Experts first test space materials. Specialists perform non-destructive testing of fatigue cracks. They check special tiles used for the spaceship thermal protection. Acoustic emission is monitored, engineers perform other relevant procedures to make sure that the spaceship can withstand the conditions in space. Further, experts check and monitor the following features:
How Are Spaceships Made?
- • Chemical fingerprint;
- • Sonic velocity;
- • External insulation.
What Are Airplanes Made of?The majority of airplane models are made from materials used in space shuttles. For building aircraft, most manufacturers use lightweight durable alloys with aluminum. For the most advanced plane manufacturing, they apply titanium and graphite-epoxy.
How Are Airplanes Made?Building an aircraft is a complex process. Everything starts with a designing stage. Only after it is completed, the production starts. Modern airplanes consist of several main components:
- • Fuselage;
- • Empennage;
- • Wings;
- • Undercarriage;
- • Wings.
Aerospace ActuatorsLinear actuators for aerospace applications are irreplaceable in the aerospace industry. Aerospace linear actuators are resistant, which is crucial for conditions in the space. They provide the highest precision of movement. Linear actuator applications are easy-to-maintain.
These mechanisms are widely used in:
- • A landing gear;
- • Wing flaps;
- • Air ventilation applications;
- • Lever control systems, and many more parts of a space shuttle or an aircraft.
Electromechanical ActuatorsElectromechanical actuator systems are of the utmost interest in the aerospace industry. For electromechanical actuator aerospace applications, some specific features are needed. They are usually absent in normal actuators and actuator systems.
Electromechanical actuators are made from durable lightweight materials. These mechanisms provide a top accuracy level, offer a higher readability level, and are easy to maintain. These features are directly related to system safety.
Aerospace Hydraulic ActuatorsAerospace hydraulic actuators are more complex than electric actuators. They have found their application in:
- • Wheel brakes;
- • Flight control surfaces;
- • Spoilers, and similar.
Hydraulic actuators are indispensable in potentially inflammable or explosive environments. In such environments, electric actuators might be dangerous. Hydraulic actuators lower the risk of electric shock or fire hazard.
Aerospace Rotary ActuatorsFor building jets and space ships, rotary actuators are applied widely. They are used in flight controls, cabin doors, fuel valves, hoists, and several more systems.
Aerospace rotary actuators are highly programmable. It allows using them for the automation of systems and processes. They can be equipped with additional components such as:
- • Limit switches
- • Opto-switches
- • Potentiometers

How to Wire Up a Linear Actuator to a Rocker Switch
The simplest process to wire a 12v linear actuator to a rocker switch is to use a wiring kit. The installation kit comprises of two wires; red and black wires that are already configured with jumpers to make the connection much easier. Other items in the wiring kit include, the Molex connectors, fuse holders containing […]READ THIS POST

Using a Decibel Chart to Choose a Quiet Actuator
If you need a quiet actuator, for whatever reason (maybe the work is to be done in an enclosed space where the sound would be too much, or the actuator will be used in a non-industrial area and so needs to be quiet), the best way to ensure that you can find one is to […]READ THIS POST
