Using this solution, engineers can measure loads applied at various areas on the rocket structure, verifying the structural performance under simulated launch conditions. Read more about this type of testing here, Rocket Structure Testing

Space Dock Capture Ring Force Testing

A space company wanted to test their spacecraft docking simulator. They wished to test the forces of the actuators used during the “lunge”, when the soft capture ring is lunged forward to latch onto a space vehicle that has been mounted. They also wanted to ensure they are working properly when engaged, and that it does not go past its overload force limit. Interface suggested using multiple WTS 1200 Standard Precision LowProfile™ Wireless Load Cells to be installed to the actuators of the capture ring. Both as wireless solutions, measurements can be recorded through the WTS-AM-1E Wireless Strain Bridge Transmitter Module, which then can transmit to the WTS-BS-1 Handheld Display or the WTS-BS-6 Wireless Telemetry Dongle Base Station for the customer to record, log, and graph on their computer. Interface’s Wireless telemetry system successfully measured the forces of the soft capture ring of the space docking port with overload protection. Learn more about this application here: Space Dock Capture Ring Force Testing

Reduced Gravity Testing

In this application, Interface supplied a Model 1100 Series Load Cell, which was installed in-line with a steel support cable to actively measure the vertical load on the system. A control system was then utilized, (which includes a Model 9870 High Speed High Performance TEDS Ready Indicator), to monitor the load cell output and continuously offload a portion of a human or robotic payload weight during all dynamic motions. Using precise feedback from the load cell, the control system commanded a motor to raise or lower the subject to maintain a constant offload force. During the simulation, the system actively compensated for the subject’s movement to accurately reproduce a microgravity environment. Read more about this test here: Reduced Gravity Simulation.

Taking Flight with Interface Solutions for Aircraft Testing

/0 Comments/in /by

As a top supplier of premium force measurement solutions for the aerospace industry, one of our critical areas requiring precision accuracy and high-quality products is for testing airplanes. Interface load cells, torque transducers, and instrumentation are used regularly in testing of all types of aerospace apparatus, components, and machines, along with embedding our force sensors in aircraft for ongoing simulation tests and inflight data acquisition.

Aircraft, spacecraft, military, and defense companies such as Boeing, Airbus, Lockheed, Northrop Grumman, Bombardier, Embraer, Gulfstream, NASA, and Cessna and many others in the supply and production lines utilize Interface load cells for thrust, wing, static, and fatigue testing. While structural test applications use many types of LowProfile™ load cells, Interface also offers a wide variety of load washers, load buttons and miniature tension and compression load cells for test, production, and control monitoring applications for aircraft.

Why do aircraft testing professionals prefer Interface solutions?  One reason is our moment and temperature compensated load cells use proprietary alloy strain gages for extreme accuracy and reliability that is unmatched by other brands. Using eight proprietary strain gages per sensor, our 4mV/V output well exceeds the performance requirements for testing these specialized aerospace vehicles.

In addition, before the airplanes are even assembled, every manufactured part and components must go through rigorous testing. There are hundreds of machines that are used on the production line for the hundreds of thousands of components needed to complete these specialized craft. Interface load cells and torque transducers are found on many of these production and test machines. Our products are used to provide a wealth of insight to guide manufacturers through research, development and final build. Because testing is so inherent for any of these parts, Interface products provide reliability and accuracy when there are no exceptions.

We recently developed several new application notes on ways our products are used to test airplanes. Included below is a preview of a few of the latest additions to our application notes catalog.

Jet Engine Thrust Test

A customer wanted to conduct a static jet engine thrust test that can accurately determine the engine’s thrust, burn time, chamber pressure, and other parameters, providing invaluable data to propellant chemists and engineers. They needed a high accuracy load cell with excellent repeatability to withstand thrust forces in very harsh environments. Interface offered a 1000 High Capacity Fatigue-Rated LowProfile™ Load Cell, which is ideally suited based on their performance for this application. The load cell reacts to the thrust forces produced by the jet engine and the signals are collected and recorded to create a “thrust curve” of the engine. The performance of an Interface LowProfile™ Load Cell allowed the engineers to be confident in the data acquired from the static testing. Additionally, the repeatability of the load cell results in reduced time between tests, making static jet engine thrust testing more efficient. Read the new Jet Engine Thrust Test application note here.

Aircraft Yoke Torque Measurement

An aircraft manufacturer wanted to measure the torque of their aircrafts yoke or control wheel. They also wanted to monitor the torque and forces applied to ensure that the aircrafts controls are operating properly. Interface suggested using the AT103 2-Axis Axial Torsion Load Cell to measure both torque and force within this single sensor. It can be installed inside of the yoke, and can measure the rotation of the yoke, and the forward and backwards movements. Data can be measured and paired with the SI-USB4 4-Channel USB Interface Module and displayed with the customer’s laptop. Using this solution, the customer was able to measure and monitor the torque and force of the yoke control. Read the Aircraft Yoke Torque Measurement application note.

Aircraft Engine Hoist

An aerospace company wanted to test their aircraft engine hoist in order to safely lift, remove, or install engines efficiently and safety. Interface’s solution was to install WTSSHKB-HL Wireless Bow Shackles to the aircraft engine hoist. A heavy load was added to the hooks where the aircraft engine would be. Results from the heavy load are then sent wirelessly to both the WTS-BS-4 USB Industrial Base Station attached to the customers computer or laptop, and the WTS-1-HS Handheld display for single transmitters. With these products, the customer was assured that the aircraft engine hoist was strong and secure enough to lift a heavy engine when installing or removing an engine inside of an aircraft. Learn more about the Aircraft Engine Hoist application here.

Aerospace and Defense Industry Solutions

/0 Comments/in /by

Among the many applications Interface products are used for across multiple markets, there may be none that require the highest levels of accuracy, quality and reliability as does the aerospace and defense industry.

By classification, aerospace largely comprises of those engaged in producing and servicing of commercial aircraft. The defense market is defined as those providing military weapons and systems designed to operate in the air, in the sea or on land.

The aerospace and defense industries are global markets that continue to expand their use of precision sensor technologies for advancing innovations in autonomous vehicles and flight systems, electric and hydrogen engines, as well additive manufacturing applications. Interface proudly serves the world’s largest manufacturers and suppliers in the aerospace industry by providing world-class force and torque measurement solutions for these types of requirements, as well as for their future inventions.

Over the past two years, the trends in the global commercial space ecosystem along with defense needs have created unique requirements that benefit from our five decades of being a premium provider for A&D equipment manufacturers and testing labs. We are able to meet these trending demands through our standard, engineered to order and completely custom force, torque and systems. These solutions are being utilized in testing of all types of vehicles, on the ground, in the water, and for flight.

A&D is a unique industry because of the complex needs of many applications. When we develop applications for other industries, we’re typically focused on solving a few specific challenges, whether it’s related to cost, safety, performance, environment, or other engineering specified design requirements. In aerospace and defense, every one of these factors needs to be addressed, as well as some special needs. Applications in the aerospace and defense industry cannot fail. If they do, it can put people, both military and civilians, in danger. That’s why force products in the defense industry need to be of the highest quality in all key factors.

Below are a few applications for force measurement in the defense industry. Each demonstrates the criticality of proper force testing, as well as the complexity of the projects Interface has been involved in.

SLS Tank Test

As outlined in NASA’s article on the SLS Tank Test, NASA’s goal was to push the very limits of a test version of the world’s largest rocket fuel tank. The project put incredible flight test strain on the tank to try and push it to its breaking point. After five hours of testing and more than 260% of the expected flight load, the tank finally buckled. Doing this helped engineers gather data on the tank to help intelligently optimize the final rocket ship.

In this application, load cells played the key role of collecting the flight force data. The extreme nature of the flight tests meant that the load cells needed to be incredibly durable and provide accurate data all the way through the breaking point.

Structural Testing

For the many hundreds of thousands of commercial and military vehicles on the market, especially those that fly, there are numerous force tests involved to validate a design and ensure they’re safe and of the highest quality to move into production. Load cells and torque transducers are used across a wide variety of vehicles for structural testing. The torque of the helicopter rotor is measured and validated using a torque transducer, or the wings and hull of an airplane are put through wind tunnels and other stress tests with load cells installed to collect data. All of these force applications are critical to ensuring that these vehicles can last beyond their intended breaking point and offer complete peace of mind to operators and passengers. There are a million different things that a military pilot is thinking about – the structural integrity of his or her aircraft should never be one of them.

Custom Sensors

Another area that has grown in recent years as technology pushes the aerospace and defense market forward is custom sensors. Test has gotten more sophisticated as the move to big data becomes more prevalent, and Interface has addressed this by working directly with customers to develop custom sensors that address unique challenges.

One of the biggest areas where we have seen a growing need for custom sensors is on test stands in thrust application. Test stands are often used in field testing on rocket or plane engines. In certain field applications, the test stand is outfitted with numerous load cells that must be custom designed with features like weatherization, multiple bridges, very-high precision, and more. The reason for this is because the cost of a thrust test in fuel alone can be incredibly high. You usually only get one shot at a successful thrust test. If there are any issues with the sensor, it’s going to be costly.

Interface has deep experience developing custom sensors for our aerospace and defense partners. We understand their needs and work closely with their engineering team to ensure they get it right the first time.
