Aerospace MEMS Based Sensors

Aerospace MEMS based sensors

Aerospace applications based MEMS sensors include the ability to eliminate conventional flight control surfaces, reduce resistance, providing lift-on-demand and improve aerodynamic performance of compressors, turbines and intakes. Consist of complete and inertial navigation units on a single chip. They are ideal for applications in hazardous environments (e.g., high temperatures, vibration, flows erosive and corrosive media). They have the bias of long-term stability and high reliability. Capacitive accelerometers are specifically designed for harsh environments and therefore critical security applications (IMU), title of the attitude and system (AHRS) reference product inertial measurement unit. They are used in the aerospace industry, missiles, and precision munitions.

Inertial navigation systems

Sensors are used in inertial navigation systems to determine the location and orientation. Measure the change from a single point of departure in three dimensions. Instrument measurements provide the remaining information. Motion sensors measure changes in acceleration, time, and rotation. Used in accelerometers to allow the calculation of the speed and distance speed and time together. Gyroscopes allow calculation of rotation, including heading. Based MEMS sensors can measure gyroscopic inertia, the tendency of rotating objects to maintain a fixed orientation, resisting forces trying to bend them.
Rotation is measured against a stabilized reference or axis line. When the aircraft right turns, the gyroscope turns left.

Ring laser gyroscopes

Ring laser gyroscopes operate by exciting atoms in a plasma to free electromagnetic energy in a cavity. Each end of the cavity reflects the energy back and forth, and forms a stationary wave pattern. The wave frequency is the measure that is used.
