Delivering Precision in Flight: The Role of LVDTs in Military Fighter Jets and Helicopters

Friday, May 26, 2023

In the rapidly evolving world of military technology, the need for robust, reliable, and highly precise sensing solutions cannot be overemphasized. Whether in the air or on the ground, the performance of our military fleet hinges on the quality of control and measurement systems in use. This is where Sentech’s Aerospace Linear Variable Differential Transformers (LVDTs) and Rotary Variable Differential Transformers (RVDTs) come into play.

Sentech: Unparalleled Quality, Custom Design

Sentech is recognized for its custom-designed, cost-effective LVDT and RVDT solutions that stand unparalleled in the industry. The company’s cutting-edge fly-by-wire and brake-by-wire technologies equip our military to outmaneuver adversaries efficiently. Furthermore, Sentech’s multi-channel LVDTs and RVDTs provide the redundancy essential to ensuring our soldiers' safety in battle.

Sentech offers AC or DC units tailored to meet long-term life requirements. All of their offerings adhere to RTCA-DO-160 and MIL-STD-810 standards, underlining their commitment to quality and durability.

Applications in Military Fighter Jets and Helicopters

LVDTs and RVDTs are instrumental in numerous applications within military fighter jets and helicopters. Their precision and reliability make them invaluable tools in the following areas:

Flight Control Actuators

LVDTs and RVDTs are crucial for measuring and controlling the position of various flight critical control actuators, including ailerons, elevators (or stabilizers), rudders, flaps, spoilers, and stabilizers. These components play a critical role in controlling an aircraft's movement, making the accuracy and reliability of the LVDTs and RVDTs indispensable.

TRAS – Thrust Reverse Actuators

Thrust reverse actuators are essential for slowing down an aircraft during landing, and LVDTs and RVDTs provide the critical position feedback required for these components to function effectively.

Valves and Engine Systems

LVDTs and RVDTs are commonly used in various engine systems, including engine bleed air systems and fuel controls. They provide vital position feedback for valves and other components, helping maintain optimal engine performance and safety.

Fly-by-Wire and Brake-by-Wire Systems

These systems replace conventional manual controls with an electronic interface. LVDTs and RVDTs play a pivotal role in these systems, providing accurate position feedback that allows for precise control.

Landing Gear Feedback and Nose Wheel Steering Systems

In both landing gear systems and nose wheel steering systems, LVDTs and RVDTs are employed to provide crucial position feedback. This data is key for ensuring safe landing, taxiing, and take-off procedures.

In the demanding environment of military aviation, LVDTs and RVDTs stand out for their durability, precision, and reliability. With over 30 years of experience in the field, Sentech continues to deliver solutions that meet the rigorous requirements of military applications. Whether for fighter jets or helicopters, Sentech’s custom-designed LVDTs and RVDTs continue to set industry standards, ensuring our military remains a step ahead in the skies.
