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

Published on Sep 30, 2018

Watch Combat Approved series:… 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 –… 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 HUGE thanks to my Moon Walker Patreon supporters!

The Only Number That Matters

Published on Mar 7, 2016

For more information, go to… Ever heard of the numbers of nature? You really need to know about them because they’re in everything … plants, animals, the human body, artwork, our DNA, the stock market, the planets … you name it, nature’s numbers are there somewhere. The guy that discovered them 900 years ago is the man from Pisa. No, not your Pizza delivery guy … Pisa is a city in central Italy famous for the leaning tower and this man … Leonardo Fibonacci … nice Italian sounding name. These numbers of nature were so revolutionary, that they bear his name even today. It starts with a simple sequence of numbers … here’s how they work: You start with 0 and then 1 and then you simply add the last two number together to get the next … so 1, 2, 3, 5, 8, 11 and so on. Now when you divide any number by the one following it, you get what we refer to as the Golden Mean … .618. It’s also called phi. This is the number that’s in everything … It’s all through nature … it’s all through the stock markets … it’s in our DNA … it’s in music … and it been in architecture since before it was discovered. For example, the Parthenon… one of Greece’s most prized assets … if it’s not now owned by Germany …. It was built in the 4th century BC … many centuries before Fibonacci. And yet it seems to be proportioned closely to the golden mean. The lower portion is about 62% of the total height. The reciprocal is .382 and together, these two numbers occur over and over in artwork because we humans find the ratio pleasing. Something as simple as playing cards, for example. You can then take that “golden rectangle” to humans. It frames the face and positions the eyes, nose, and mouth. The belly button seems to generally divide the body into the golden section. You have 5 fingers, each one with 3 bones perfectly proportioned to the golden mean. You’ll find the golden mean in our DNA. You can see the numbers of nature at work in sunflower leaves. They arrange themselves in Fibonacci layers. There’s the Fibonacci spiral, evident in hurricanes … and sea shells. It goes on and on. In the stock market, when stocks are trending, the waves they form are in ratios of phi. You find it over and over again and many traders use it to trade quite profitably. So, the markets are not random, as so many think. They’re quite predictable. And where could these ratios in nature that we find everywhere on Earth originate Well, let’s look to the heavens. The planets are more or less separated in distance by the golden ratio. They actually follow more of a sine wave. But if you were to take the distances and average them, you’d find they come out to 1.618 … phi! We know that we’re affected by electromagnetic waves from the planets … we just don’t know exactly how we’re affected. But that’s a thought from another video. Is God a mathematician? Well, there’s certainly order to the universe and as we delve deeper and deeper into science, we’ll no doubt find more of the answers.


Paper written in 2008, just before the market crash, Subject what it would take to convert personal transportation from petroleum to electric power.

The following text in taken from a paper I write in 2008 when it looked like Gasoline might hit $5.00 a gallon by the end of the year and it looked like we could be running out of oil. Obviously, that did not happen because a couple of months latter the Market crashed and a project I was about to finish — was finished as well as all capital dried up and I lost close to $500,000 of investment of which this paper was only a part.  The logic and engineer is still sound today although the financial numbers would need to be adjusted.  Attached at the end are a copy of the paper and the related power point presentation.

There are almost 250 million vehicles (cars, pickup trucks and SUV’s) on U. S. roads used for personal transportation. They all use some form of ICE as the power source.  They also all use some derivative of petroleum as the fuel i.e. gasoline, E85 or diesel fuel and thereby emit million of tons of CO2 into the atmosphere (about 20 lbs of CO2 per gallon of gasoline burned).

When this transportation system was started emissions and the supply of fuels were hardly on anyone’s mind and so what we have today is a system built with millions of hours of hard work and billions of dollars of capital investment. Today, in hind sight, we might have chosen a different path had we known better. However, this system has served us well for over 100 years and has contributed to the reasons we have the best place in the world to live.

But now we have rising CO2 emissions creating global warming and petroleum supplies running out and both creating issues that threaten our very way of life. So we find ourselves searching for a way out of these serious predicaments that many of us see.  One group focused on the environment sees CO2 emissions which are leading to Climate Change as the most important issue. The other side focused on Economic Growth sees the supply of cheap petroleum “Energy” as the most important issue since without that supply the world economy could collapse.

Both sides have valid points but for some reason they can’t seem to see, how by working together, they could come up with alternatives that satisfy completely both points of view. That would not seem possible, but it is and it will be shown to be so in the body of this White Paper.

The solution is right before our eyes and we just need to focus on the results we want. Doing that shows us that by switching Personal Transportation from gas/diesel fuel to electric power both issues can be solved in one project. From an all-electric vehicle production point of view this process could be started today with existing technology and, in fact, several automakers are planning on introducing limited capacity electric or electric hybrid cars by 2010.

Therefore, why write this paper if these alternative vehicles will soon be for sale.  The answer is that although building the vehicles is now possible albeit with limited driving range to start, there is no infrastructure in place to deliver the electric power to them in the quantities required to convert even a small percentage of today’s almost 250 million vehicles to electric vehicles let alone those yet to be produced.

The bottleneck here is finding a way to deliver the electric power equivalent, of the gasoline that those ICE’s now use, to the electric cars in the form of electric power.  That delivery system has three parts; first the electric power generation, next is the transmission of that power to the user and lastly is the charging of the vehicles battery. All three elements are required before the production of the electric vehicles can begin in earnest or it would be the equivalent of building ICE vehicles and having no gas stations.  Unfortunately the first two “The Grid” is already close to capacity and has its own problems, so we seem to be at an impasse.

A classic chicken or egg quandary … No electric cars, no reason to expand the Grid … No Grid capacity, no reason to build electric cars.
