The Importance of Silicone in the Aerospace Industry

Silicone seals, gaskets and hoses may seem humble things, and often taken for granted, but without them, a lot of groundbreaking technology would be impossible. With better resistance to stress, heat, and oxidation than rubber, silicone products help industries like automotive and aerospace push ever further beyond their previous limitations.

Strong Market Growth Predicted

A market trends analysis from Grand View Research published in January 2019 predicts strong growth in aircraft and aerospatial industries over the next decade.

Global aerospace parts manufacturing was an 849-billion-dollar-market in 2017 and is expected to continue to grow at around 3.8% until 2025. New generations of lightweight and more fuel-efficient aircraft will drive most of the growth and depend on materials with better temperature tolerance, like silicone, PTFE, FFKM, titanium aluminide, and aluminum lithium. Elastomers like silicones and FFKM readily tolerate temperature extremes between -55 °C and +300 °C.

Another report from the same source predicts similar growth in the silicone market over that period. Globally it was valued at $14.17 billion in 2018 and is expected to grow at 4.5% per annum up to 2025. This figure includes increased use of silicone as an oil additive, as an insulator and sealant for electronic components, and for more familiar roles such as silicone hose and gaskets. Various silicone hose products are available from suppliers such as https://www.goodflexrubber.com/pages/silicone-hose-manufacture.

New Aircraft

The projected growth is tempting for new companies to enter the aerospace market. American start-up Hermeus, based in Atlanta Georgia, proposes building a commercial airliner capable of reaching Mach 5 – that’s around 3800mph. By comparison, Concorde had a cruise speed of just over Mach 2 (about 1330 mph), and a conventional liner usually flies at just 600mph or lower. If the liner is built, it will mean a flight from New York to London will take about the same time as a train journey from Leicester.

Hermeus intends to use combined-cycle turbine engines. Elastomers play a crucial role in these engines, as well as in the latest hydraulic systems, gearboxes, and airframes, by allowing the aircraft to handle the harsher temperatures generated by more powerful engines. They are also more chemically resistant to the oils used to lubricate turbine engines and hydraulics. The greater resistance of silicone and other new elastomers to deformation under pressure also helps minimize expensive maintenance regimes.

Reduce your risk of football injuries with these exercises

According to a recent study, the most common football injuries sustained during training, are the hamstring, quadriceps, calf and lumbar disc injuries. However, doing just three things can reduce your likelihood of landing all these injuries.

This is welcome news, as over 80% of players pick up at least one injury per season and this injury will be enough to make them miss at least two games. But these three things are self-explanatory. Players need to ensure, they get enough sleep, get the proper nutrition and engage in mobility drills. They should also wear the appropriate kit such as Nike Football Kits which they can find at places like www.kitking.co.uk/brand/nike

But what kind of drills are the best?

Prehab before rehab

Prehab has become somewhat of a buzzword in football and while it does sound a little gimmicky, studies show it really works. Prehabilitation is a form of strength training for the entire body, regardless of the sport being played. It aims to prevent injuries before they occur and can also increase performance on the field.

Hindu press up

One of the most talked about prehab drills is the Hindu press up. With your feet slightly wider apart than your shoulders, you lean forward to create an inverted ‘V’ shape. Now keep your legs straight and bend your arms until your chin hovers above the floor. Then arch your back, which will shift you forward and lead you to look up towards the ceiling. Complete the move by raising your hips again to make the inverted ‘V’ position again.

Taking inspiration from yoga, this flow can be repeated 10 or 20 times and will work muscles from head to toe with very little risk of injury.

Ankle alphabet training

This exercise is all about creating a variety of movements with a goal, i.e. completing the alphabet. To begin, stretch out your legs in front of you, lift one leg off the ground and use your pointed toes to draw the letters of the alphabet. Patience and practice are important here. Aim for accuracy to get the most out of this flow.

However, it’s important to remember, no exercise is an absolute guarantee against injury but you can make it less likely with drills and prehab work.
