Aerospace & Defence

Reliability and high performance of products under harsh environment and extreme conditions are often required by military applications. Bestech Australia supplies high precision and excellent capability products meeting military-grade requirements, such as high g shock accelerometers with integral digital temperature compensation recommended for flight test applications.

High “g” accelerometers are also utilized in jet airflow fields and inlet pressure, wind tunnel testing and turbulent airflow measurement. High intensity models for blast test situation and underwater-exposure are available along with advanced fire-proof, overload-protected features. Bestech also supplies pressure distribution films to Defence to study the effect of blast overpressure on structures.

Stress tests on aircraft wings

Aircraft wings hold an utmost importance in the proper functioning of an aircraft and durability and hence should be thouroughly tested for vibration and bending behaviour under various stress conditions. These factors are highly significant for the optimization of certain parameters such as service life, safety and fuel consumption. For carrying out these structural tests, special sensors by Micro-Epsilon are used for displacement measurement.


Lift height of a catering vehicle

Modern airlines use catering trucks for loading and unloading an aircraft with food. The operation is based upon a hydraulic scissor-type mechanism that raises the body of the truck until it is aligned with the supply door. Since the supply door is located above the aircraft wing, the complete van body is moved in the longitudinal direction. Now, the docking process may be affected by the change in oil viscosity due to ambient temperature conditions. Hence, the movement of the van body is detected with the help of a reliable measuring system.


Position monitoring of aircraft wings

The wings of the aircraft have slats on the front side and flaps on the rear side which act as buoyancy aids. Therefore, they need to be checked for unevenness in their dimensions and size to ensure the  aerodynamics of the aircraft isn’t disturbed. Spindle drives are used to retracted and extend the slats and flaps of aircraft wings. The spindle is connected to the drive motor in the gear bay via the drive shaft. To prevent any uncontrolled movements of the floating head and avoid any uneven extension of the slats and flaps, a Wing Tip Brake is positioned on the shaft in the outboard wing area.


Monitoring cabin pressure in aircrafts

An aircraft generally ascends several hundreds of feet high in the air and at this height, the pressure gets significantly low, thus providing a very limited amount of oxygen to breathe. To cater to this situation, cabin pressure is provided to ensure that flyers can breathe comfortably the entire trip and no health issue is faced. To accommodate fresh air into the cabin, jet turbines on the outside of the aircraft spin and compress air as it makes its way back into the plane. Pressure sensors help in this case to measure air pressure during the entire journey to ensure that all parts of the pressurization system are fully functioning.
