@dr_obbs @bernie_collins1 @RacecarEngineer I’m so glad you like those articles! I realised there was little info out there that actually explains the mechanics of grip so I thought I’d write my own! 😁

[Gemma Hatton @Gem_Tech]

In this piece, I explain:
➡️ How e-motor dynos work
➡️ Permanent magnet motors
➡️ PWM switching frequencies
➡️ Silicon carbide inverters
➡️ Battery emulators
➡️ Typical test programmes
➡️ Latest F1 testing strategies

The most difficult piece I have written in a while, but I learnt so much on EV powertrain testing!💡

Huge thanks to the companies who helped me with this piece 🙏

A sneak preview below ⬇️

@CallumJCParr @mattpt55 Haha! I feel like I’m a bit out of the loop with the whole F1 scene at the moment so not sure I could add much value but I think I still have my mic somewhere! 😅

When I was in F1, one of the tyre blankets was removed too early so the car left the garage with one tyre a few degrees cooler. This never got up to temperature throughout the stint 🥶

F1 tyres are so sensitive, one degree can significantly affect performance 🌡️

[Racecar Engineering @RacecarEngineer]

How long do @F1 tyres spend in tyre blankets and what temperature are they heated to? 🕒🌡️

⚪🟡🔴 SLICKS -> Maximum of 2hrs at 70degC
🟢 INTERMEDIATES -> Maximum of 2hrs at 60degC
🔵 WETS -> No preheating allowed

@Lew15H Yeh I actually wrote an article for @RacecarEngineer on the difference between road/street courses and ovals with that pit lane closed rule - was so interesting!

[Gemma Hatton @Gem_Tech]

@momedic9019 Ah I see - thanks. It’s difficult to get IndyCar in the UK! So do they mostly overcut rather than undercut because of the slower warm up on new tyres?

Engineers have a crucial role in innovating technologies that can help us be more efficient with the world's resources, time & money 🌍
If you know anyone who is interested in engineering, whatever their gender, race or background then spread the word - engineering is awesome

Happy International Women in Engineering day! ⚙️ 🎉

Hi five ✋ to all the incredible female engineers I have met throughout my career - you are inspirational so this is an appreciation post for you 🙏

Engineering is not just a subject, it's a way of thinking and approaching problems. It can lead to building racecars, aircraft, rockets or wind turbines 🚀

We need more engineers!

[Gemma Hatton @Gem_Tech]

@Rhinopt Haha no wonder what a race it was! I’m a bit out of the loop with endurance racing at the mo, but I switched it on and just couldn’t switch it off!

[Gemma Hatton @Gem_Tech]

Hello Twitter 👋
It's been a looooong time since I posted anything - how is everyone's June going?

Mine had a wobbly start but the strategy has come good the last week! 😅

@NIO333FormulaE “It’s a bugger this walking stick has a wheel attached to it”
“At least you’ve got one…”

[Gemma Hatton @Gem_Tech]

@NIO333FormulaE @zoejj73 What a guy 😅

[Gemma Hatton @Gem_Tech]

@JennieGow Really sorry to hear this. You are one of the nicest motorsport people I have ever met. Be patient with yourself as you recover, work will always be there. You’ve got this Jennie 💙💙💙

@PhilippePuetzer ✅ only just made my flight!

[Gemma Hatton @Gem_Tech]

Can you tell when I was trying to get to Heathrow and the M25 was shut because of protestors? 🥲

[Gemma Hatton @Gem_Tech]

For all my @F1 followers - check out @brrrake and watch the race alongside a former F1 trackside engineer!
Can't get better insight than from someone who has actually been there and done it! 🏁

[Gemma Hatton @Gem_Tech]

@JulianClary Yep - me too! Hi five 👋🏻
