Missiles operate in some of the most demanding conditions. They can experience massive heat flux when going through the layers of the earth’s atmosphere and because of the sheer speed that the missile is traveling at. With speeds in excess of 10,000 kilometers per hour, they require components that can provide reliability and precise motion under these conditions. And with the need to respond to higher demands for performance, the technology powering these missiles needs to deliver more torque and power in relation to weight.
For rapidly evolving Aerospace and Defense (A&D) requirements, engineers are facing many challenges to keep up with ever evolving demands. From supply chain issues to changing government regulations, companies are being tasked with not only navigating these global issues but also providing more value-based technologies, reliable products, and constant innovation.
An explosion proof motor is clearly marked with a nameplate that identifies its suitability for a given hazardous environment. The nameplate will indicate the hazardous Class, Division, and Group for which the motor is suited.
Electric motors generate heat under normal operating conditions and have the potential to generate a spark if a motor coil fails. Excessive motor case temperatures or a spark that is not properly contained can cause an explosion or ignite a fire in environments where specific hazardous materials are present.
Electro-Optical/Infrared (EO/IR) Systems are used to provide long distance visual and thermal imaging for a variety of applications. Often used in satellites, planes, and military applications, there are two main components found in EO/IR systems: sensors and the motion system. While both the sensors and motion systems need to be reliable in many environmental conditions, let’s take a look at the 5 Harshest Environments for EO/IR Motion Control Systems.
