ЧТО ДЕЛАТЬ ЕСЛИ ПОРВАЛ ГУСЕНИЦУ, ПРОВАЛИЛСЯ ПОД ЛЁД, МОРОЗ -600 °C

Summary

The script describes testing of an off-road vehicle called Shishiga in winter conditions. It details starting issues in extreme cold and solutions like an autonomous heater. It talks about tread repairs needed from damage caused by freezing. There is discussion of upgrades being made for future models, like new cabins, drivetrain improvements, and better tires and tracks. Overall it conveys the ongoing development of Shishiga to become a reliable, serially produced off-road vehicle.

Q & A

What challenges did the team face when testing the vehicle in extreme cold temperatures?

The auxiliary heater in the cabin was not powerful enough to pump fuel through the long fuel line to the engine when temperatures reached -30C. This caused issues starting the engine.

How did they solve the fuel freezing issue when temperatures were extremely cold?

They added a small fuel tank by the auxiliary heater so it only had to pump fuel a very short distance. This allowed the heater to warm the engine enough to start even after being completely frozen.

Why does the vehicle need crawler gears?

The vehicle has a minimal engine for its chassis size. Testing showed that even on flat ground with knee-deep snow, the maximum speed was only 45 km/h with the crawler gear engaged. The direct gear is not necessary in these conditions.

What changes are planned for the tracks on future models?

The tracks will have some undisclosed technological improvements to make them more durable and increase their service life. The goal is for them to last as long as when they were new.

What will the new cabins for future models look like?

The new cabins are still in development, but will likely have a higher and more angled front nose. The radiator will be much larger and mounted higher on the front.

How will the cooling system be changed on future models?

There will be one large radiator up front with a big fan pulling air through it. All other coolers will connect via heat exchangers rather than additional radiators.

What creature comforts are being added for the driver?

High quality air suspension seats are being purchased that allow height adjustment. They have integrated seat belts and arm rests for driver comfort on long expeditions.

Will future models be certified for legal use on public roads?

Yes, future production models will go through certification to receive papers like the PTS. Owners will be able to legally register them.

How will unfinished development versions be sold?

They plan to offer pre-production models for sale at affordable prices. Those who purchase them will get free upgrades to final parts once ready.

When does the team expect the new models to be ready?

They don't want to make empty promises, so have not provided specific timelines yet. The goal is to eventually reach serial production.
