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.

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. Bestech Australia offers WDS-xx-P115 series draw-wire sensors from...


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. Bestech Australia provides sensors in the series P60 employed for the vertical measurement of the wings during the structural tests. These sensors give very outstanding price/performance ratio and are easy to install and operate. The draw-wire sensors are fitted to the...


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...


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...


Cyclic Load Testing of Composites in Aerospace

In recent times, composites have rapidly replaced metals in aerospace structures due to their advances in weight reduction, thereby increasing component strength. With that, it can be expected that the need to periodically measure service strains on these materials will increase correspondingly.  This is because the composites undergo a change in their mechanical, thermal, and chemical properties as a result of their changing directions, unlike metallic materials. These materials have differing stiffness properties in different directions.  For this reason, cyclic load testing is performed on aircraft structures to generate fatigue life and crack growth data, identify critical locations and demonstrate the safety of a structure...


Wind Tunnel Testing in Aircrafts

Researchers use wind tunnels to test scale models of aircraft and spacecraft to address the aerodynamics problems of aircraft as they are developed. They measure and analyse the force and moments acting in all three directions (x, y, z,) on a test model. During the test, the airplane model is placed in the test section of the tunnel and air is flown past it.  The process demands high levels of balance and utmost precision to withstand the severe test conditions. This is achieved by using strain gauges that provide ease of installation, remote-controlled measurement, high reliability and endurance in harsh conditions. In this application,...
