The World’s Best Automatic Transmission – How Autos Became Cool Again


Engineering Explained

Published on May 1, 2019
How The Best Automatic Transmission Works. ZF’s 8-Speed Auto can give modern dual clutch transmissions a run for their money. It’s light, compact, quick-shifting, and shifts are incredibly smooth. The automatic transmission was a game changer. No longer were three pedals required, drivers could relax as they had one less thing to worry about on the road. But the automatic transmission had many flaws. It was inefficient, shifts were slow and often rough, and automatics were big and heavy. ZF introduced the world’s first production 6-speed auto in the 2002 BMW 7-series, but just a year later VW introduced the first production DCT in the European market Golf R32. The dual clutch was faster to shift, efficient, and gave drivers a direct feel. Was this the end for modern automatics? Not quite. ZF introduced their 8HP, an 8 speed automatic that swept the industry as a result of it’s shift quality, shift speed, efficiency, size, and cost. We’ll learn all about it in the video.

Opposed Piston Diesel Engines Are Crazy Efficient


Engineering Explained

Two-Stroke Opposed-Piston Diesel Engine By Achates Power EE Shirts! – http://bit.ly/2BHsiuo Recommended Books & Car Products – http://amzn.to/2BrekJm Subscribe for new videos every Wednesday! – https://goo.gl/VZstk7 The Achates Power opposed-piston engine is packed full of unique technology. The supercharged, turbocharged, diesel 3 cylinder makes use of six pistons, two of which operate in each cylinder. It’s a two-stroke design, meaning every time the pistons come together a power stroke occurs, forcing both pistons away from one another and rotating their respective crankshafts. The two crankshafts are geared together to a common output shaft, which powers the vehicle. Research has shown two-stroke opposed piston engines to be wildly efficient. 3 cylinder designs are the most efficient, and it’s possible to achieve brake thermal efficiencies as high as 55%, a massive improvement for road car engines. The engine in this video is a 2.7L 3-cylinder producing 270 HP and 480 lb-ft of torque.

MiG-31: The Near-Space Plane. Russia’s super-fast interceptor


Published on Sep 30, 2018

Watch Combat Approved series: https://rtd.rt.com/series/combat-appr… Imagine flying a plane so high that the world looks spherical and the sky is pitch-black. The Mikoyan Mig-31 fighter is the only jet plane in the world to make it possible to fly on the very edge of space. With an incredible speed of 3,000 km/h, the Soviet-designed interceptor is the world’s fastest serving aircraft, and it can fly twice as high as a commercial flight. Travelling at more than twice the speed of sound, the MiG-31 can touch the stratosphere and breach what’s known as the Armstrong limit. beyond which a pilot’s tears and saliva would boil without a pressure suit. Even at such incredible heights, the MiG-31 can still deal with its enemies. The fighter is armed with long and short-range missiles that can be launched against high-speed targets. At Khotilovo air base, RTD attempts to give viewers a first-hand experience of near-space travel aboard this unique aircraft by mounting cameras on the airframe and inside the cockpit. See what breaking the sound barrier looks like and why, despite being designed in the 1970s, the MiG-31remains at the top of its game and unrivalled to this day.

Is SpaceX’s Raptor engine the king of rocket engines?


Published on May 25, 2019

2:55 – Basic physics of rocket engines 6:10 – Rocket engine cycles 20:30 – Rocket fuel comparison 30:40 – Raptor vs other rocket engines 44:05 – Summary Article version – https://everydayastronaut.com/?p=9823… SpaceX’s new raptor engine is a methane fueled full flow staged combustion cycle engine and its so hard to develop, no engine like this has ever flown before! Now this topic can be really intimidating so in order to bring the Raptor engine into context, we’re going to do an overview of a few common types of rocket engine cycles then compare the Raptor to a few other common rocket engines, like SpaceX’s current work horse, the Merlin, The Space Shuttle’s RS-25, the RD-180, Blue Origin’s BE-4 and the F-1 engine. And if that’s not enough, not only is SpaceX using a crazy engine cycle, they’re also going to be using Liquid Methane as their fuel, again something that no orbital rocket has ever used! So we’ll also go over the unique characteristics of liquid methane as a rocket fuel and see if we can figure out why SpaceX went with Methane for the Raptor engine. We’ll also break down and explain all the different engine cycle types so you know what the full flow staged combustion cycle is, how it works, and how it compares to the other cycles. So by the end of this video hopefully we’ll have the context to know why the raptor engine is special, how it compares to other rocket engines, why it’s using methane and hopefully find out if the Raptor engine will be the new king of rocket engines… ———————————————– Rocket engine renders by @MartianDays https://twitter.com/MartianDays HUGE thanks to my Moon Walker Patreon supporters!
