Acceleration Solutions

Flight Control and Guidance

To meet demanding contemporary aircraft performance requirements, Flight Control and Guidance Systems compute and display aircraft position and orientation while executing many routine adjustments to attitude and direction in the course of a flight.

Accelerometers for flight control applications require high accuracy, exceptional reliability and conformance to stringent qualification standards such as RTCA DO-160. LSM Series accelerometers with 100,000 hour MTBF reliability and up to 20g full scale sensing range are critical components detecting longitudinal, lateral, and normal accelerations for aircraft wind shear detection, AHARS and autopilots worldwide.

Fatigue Monitoring

Repeated stresses applied to a structure produce failures that would not be caused by a single load application. Structural fatigue is often the factor that determines the life of an aircraft, and aircraft of a given type can fly totally different profiles to perform the same mission. As a result, there is a need to determine the magnitude and number of airframe acceleration exposures for each aircraft.

The LCA-167-10g accelerometer with its unipolar 28 Volt DC aircraft power input, accuracy better than 0.10g from all error sources combined, input to output electrical isolation, and MIL-STD qualification is specifically designed for fatigue monitoring applications.

Image Stabilization

Active image stabilization for vision and target acquisition systems requires precisely accurate inertial sensors to minimize the errors caused by sensor noise, bias, or phase delay. Jitter reduction is accomplished by measuring the vision or target acquisition system motion, and applying a physical position or pilot/operator display correction using sophisticated signal processing techniques.

Jewell's unique wide bandwidth ASXB-100 angular accelerometer is a vital component for military image stabilization and aviation flight control. The ASXB incorporates force balance fluid rotor technology to achieve a high level angular acceleration output with unrivaled accuracy, stability and linear acceleration rejection.
