We are proud to support our country’s military actions.
Acceleration Solutions
Missile Guidance
Smart weapons rely on integrated missile guidance systems to deliver strikes accurately and evade enemy detection systems. Accelerometers are an essential component of these systems. Accelerometers such the ASMP collects the input data utilized by the guidance control computer for course correction and flight stability so that the missile will reach its intended target.
Weapons Control & Targeting
An angular accelerometer has the sensitivity to communicate between the aircraft and its weapons. Our ASXC series Fluid Rotor Angular Accelerometer offers high-precision up to 0.001 rad/sec2, meets MIL-STD 202 standards and has exceptional performance in environments with high vibration & shock.
Aircraft Flight Testing
Flight testing is performed to evaluate the flight characteristics of an aircraft and to validate its design. Once the flight test data requirements are established, the aircraft is instrumented to record data for analysis. The testing can range from measuring the performance of a minor existing system modification to complete development and certification testing of a new aircraft. Since flight testing can be particularly dangerous work with the objective of acquiring the most accurate possible engineering test data, highly accurate and reliable instrumentation is required.
The Jewell ASBC series was especially design to accurately measure angular accelerations from ±200 radian/second² to ±1000 radian/second². Combined with 0.005 rad/sec2 resolution, rugged package, 100G shock resistance and wide operating temp range from -55 to +95°C, this model makes a great solution for this application.
Tilt Solutions
Mobile Antenna Orientation
Where no airport landing systems exist, autonomous portable ground-based precision approach radar systems play a key function in providing air traffic services for the rapid deployment of troops and equipment. Portable approach systems require a highly stable vertical reference to precisely calculate aircraft position while guiding the aircraft to a safe landing.
The DXI-200 inclinometer enables automated leveling of mobile antenna supporting platforms by accurately measuring tilt in two axes. This DXI-200 is ruggedized, totally sealed and incorporates an integral output filter in combination with a specialized servo loop to yield an output with exceedingly low noise.
Battle Tank Fire Control
Battle tanks in warfare may not get a “second chance” if initial enemy target engagements are not successful. Control system ballistic firing solutions yielding the highest accuracy require inputs from the most accurate and robust sensors available.
The LSRP inclinometer delivers exceptional accuracy in the most demanding tank warfare environments. Capable of being located directly on a large bore gun, the LSRP survives intense shocks produced by repeated firing while consistently delivering a trigonometric angle output with better than 0.05° accuracy over a full military temperature range.
Roller Path Calibration
Roller paths for guns and gun directors are very accurately parallel to one another when a ship is constructed. Over time, structural changes to a vessel caused by rough seas, temperature changes, and varied loading cause roller path orientation to degrade and reduce gun system accuracy.
Absolute tilt sensing precision is necessary to measure the changes in roller path and restore fire control accuracy. The dual axis LCF-2330 has the required combination of unsurpassed repeatability, low thermal sensitivity and long term bias stability to insure accurate naval weapons system alignment measurement and calibration. Inclinometer mishandling and shock resistance is assured by a housing machined from a solid block of aluminum, and a fluid damped torsional suspension inertial sensor.
