Очередные видеоролики от команды Раптор –

Кстати, в оригинале двигатель подразумевался Турбо Проп RR M-250, но по ходу развития разработки получилась такая интересная версия – AUDI 3.0 TDI engine: 204 PS / 201 bhp / 150 kW @ 3750-4500 rpm…

The next consideration was how it would be powered. Most light aircraft use piston engines that burn 100 octane low lead fuel. This fuel is more expensive than other fuels and becoming even more so as it is considered a specialty fuel by the oil companies and eventually it will be phased out much like leaded auto fuel was. Diesel engines in aircraft are becoming available but they are heavy and require a lot of air for cooling. That air requirement creates drag. Recall that I am going for low drag. The ideal engine was a small turboprop. They burn jet fuel which is readily available (and will be for decades) and is cheaper than 100LL. So I did some research and found the Allison (now Rolls Royce owned) M250 series engines. They have been around since the 60’s and are a reliable engine with a fuel burn of about 21 gallons an hour at altitude. So let’s see, 345mph @ 21 gph works out to about 16 miles per gallon. Not bad considering you’ll be taking 4 or 5 almost anywhere in no time. This is cheaper than driving if you factor in hotel overnight stays that are inevitable on longer trips.
