Hydraulics in Defense and Aerospace

When thinking about hydraulic applications, defense and aerospace are quite often at the top of the list.
Many industries such as mining, construction, forestry, oil and gas, and utilities routinely use hydraulics in the operation of heavy machinery.
What is not common knowledge is that a vast amount of the technology was developed and advanced through necessity by the defense and aerospace sectors.

Hydraulics is a technology involving a mechanical function that operates through force of liquid under pressure. This force greatly surpasses the force created by electronic or pneumatic means.

Power density is the key reason for using hydraulics in military applications, particularly where power and precision are required. Hydraulic systems can provide the high levels of force necessary to operate heavy equipment, as well as the precise control needed for delicate operations.

Examples of Hydraulic Use in Defense Applications (a few, there are many!)

Controlling robotic arms

Hydraulic systems offer several advantages for defense applications, including high power-to-weight ratios, compactness, and reliability. Hydraulic systems are an essential part of defense equipment and have played a vital role in the defense of countries around the world.

From countering powerful recoil to providing precision, hydraulics take the spotlight. Using robot arms in munitions factories help reduce injuries amongst workers and enable fine precision work which would be hard for a person to undertake by hand. The hydraulics in robotic arms allow for a superior level of control and accuracy in movement. 

Lifting and positioning aircraft parts during assembly & maintenance

Hydraulics do the heavy lifting during aircraft maintenance, allowing machinery to lift and maneuver parts into the correct place safely. Hydraulics really do provide the backbone of the defense industry, allowing for much quicker and more efficient turn arounds between missions and enhancing the safety of ground crews.  

Moving heavy loads around military bases

Many military ground vehicles have hydraulic parts including loading ramps that allow for easy transport of heavy loads around bases and shipped decks. Hydraulics are often used when stability and accuracy are key, for example if munitions are being transported, it is paramount that they are done so in a safe and reliable manner.

Toronto Students Advancing Aerospace 4th Annual Conference

Along with Pratt & Whitney, Safran Landing Systems, The Sky Guys, among others, Lynch Dynamics was honoured to have been invited to address the Toronto Student Advancing Aerospace (TSAA) conference on January 26-27, 2018. Hosted at the Sanford Fleming Building on  the campus of the University of Toronto, the conference focus was on Canadian aerospace and space involvement. Lynch’s involvement included panel participation and a case study by Ken Mah on Small Medium Enterprise (SME) involvement in these market sectors. Great to experience the energy and enthusiasm of our future leaders in this industry!

It was a pleasure to contribute to the dialogue on how students can make meaningful contributions to the aerospace industry. – Ken Mah

Toronto Students Advancing Aerospace (TSAA) is an inter-university student organization striving to promote the advancement of aerospace through student leadership and hands-on initiatives. The organization hosted its 4th annual conference, featuring talks from innovators and industry leading professionals, as well as a new addition this year, an aerospace case competition on January 26-27, 2018.
