  • "It was the ultimate flying machine, No airplane can live up to what the X-15 did." That’s what retired test pilot and astronaut Joe Engle said of the first real space plane and 50 years after its record-breaking flight of 3rd October 1967 when USAF test pilot William J. Knight achieved a top speed of MACH 6.72, 4519 mph or 7273 km/h, It’s still the fastest manned powered aircraft.

    And if you thought the SR71 blackbird was the fastest jet, then you absolutely correct because the X-15 wasn’t a jet, it was rocket powered single seater aircraft which looked a bit like an oversized dart and had to launched from the underside of a modified B-52 at 45,000 feet, because the XLR-99 rocket engine would burn through all of it’s fuel in just 2 minutes.
    Not only did the X-15 set speed records it also went past the point of where space officially starts at 100km, 62.1 miles on two occasions, both times piloted by Joseph A Walker at 105.9km, 347,000 feet and 107.8km 353,000 feet.
    Although in the 1960’s the USAF considered space to start at 80km or 50 miles. Any crew that flew over the 50-mile limit where given Astronaut badges, 13 of the X-15 flights went higher than this and two of the pilots, Neil Armstrong and Joe Engle went on the become fully fledged Astronauts in the Apollo and Space Shuttle programs.
    But apart from being a record-breaking aircraft, Research from the X-15 program lead to things like the first full pressure suit that would work in space, the first use of reaction controls, those are the little jets that position a spacecraft in space, the first use of superalloys in the planes structure that could withstand the heat of hypersonic re-entry and the Development of the first large restartable throttleable rocket engine, the XLR99.
    These are a small selection of the developments and discoveries that would go on to contribute to later space programs including Mercury, Gemini, Apollo and the Space Shuttle.
    In the early 1950’s, research which had started with the Bell X-1, the 1st supersonic plane, began looking in to the problems that would be encountered by spaceflight.
    At the time it was still unknown as to what would happen to the stability as well as other issues of the craft, when travelling at hypersonic speeds, that’s between Mach 5 to Mach 10, or between about 3800 and 7,700 mph ( 6,200 to 12,400 km/h). This would be the type of speed that would be required to get to the edge of space and the re-entry.
    In 1952 the National Advisory Committee for Aeronautics (N.A.C.A), NASA’s predecessor started looking into the problems and by 1954 they had contacted both the US Navy and Airforce to propose building a research aircraft which would become the X-15.
    By 1956 the contract for the airframe had gone to North American Aviation and the rocket engine was to be built by Reaction Motors.
    After the contract had been awarded to North American and before the launch of Sputnik in Oct 1957, North American had considered making an X-15B orbital space plane that could carry a crew of two by launching it in to a low earth orbit on top of a pair of SM-64 Navaho missile boosters.
    If this had been done, it could have predated the Space shuttle by over 20 years.....

    When I was a teenager in the 60s the government released some videos of the X15 on television. When I watched these videos, I was absolutely mesmerized. I wanted so much to have something to do with that when I grew up! It is one of the main reasons I become an aerospace engineer. I am 65 and retired now but I still think the X15 had the magic. I will always love it!

      I was also a teenager then and as long as I can remember I, too, was mesmerized by aviation and spaceflight. I knew about the X-15 in the 1950s thanks to one of the big picture magazines so popular then.
      Walker was from Washington, PA; I grew up about 10 miles from there and saw him on (I think) a July 4th celebration. I was thrilled to see someone who I thought was a great man.
      I wanted to be a pilot like him but that was not to be, although I did become a civilian pilot. I also wanted to be an aerospace engineer but, well, life. I still look at the sky and the stars just about every day and never tire of the incredible beauty -- and promise- that lies just above our heads.
      We are about to become a multi-planet species in large part due to the work of people like Joe Walker.

    My dad worked on the X-15 as a control systems design engineer during his years with North American Aviation. It wasn't associated with Rockwell when he first started working for them. He also spent some time with the Apollo project. I'm proud of him for not only this, but because he grew up on a dairy farm outside a town of less than 700 people. As a teenager he was inspired by the flight of Lindbergh and announced to his family that he was going to fly airplanes for his career. The Army Air Force rejected him due to a minor peripheral vision problem so he announced he was going to build them if he could not fly them. He got an aeronautical engineering degree and started working for Lockheed a couple of years before Pearl Harbor.
    After working for Lockheed for a year or so he learned that the Army had reduced the peripheral vision requirement and retested. He passed and when he interviewed the Army realized that he was already working for Lockheed. As my dad related the Army not only told him "no you cannot enter the Air Force" they said "hell no you can't join as we need all the aeronautical engineers we can get working on new and higher performing aircraft." He had been working on the P-38's controls as Lockheed was building it for the war effort. No wonder the Army was so emphatic about him not leaving his engineering position!

    • @Mermaid4Ever
      @Mermaid4Ever 7 лет назад +140

      02markcal, my dad passed in 1990 at the age of 75. An unlicensed 16 year old driver ran a red left turn arrow and he slammed into her. His 68 Porsche only had a lap belt and he hit his head on the steering wheel. He was born in 1914 so he would be 103 years old if he was still alive.
      People really scoffed at him, both family and the rest of town, when he announced he was going to be a pilot. When he could not follow that path they scoffed at him more when he announced he was going to build aircraft. It was the depression and my grandparents didn't have the money to send him to college. No one in the family had been to college either. It took him seven years to work through college, sometimes he would have to take semesters off to earn money. I had a great uncle who had an ambulance dealership and he always gave my dad a job when he needed it. Even during the depression ambulances needed service and my great uncle managed to sell them during the depression, so the income was fairly good in spite of the economy. A bonus was my dad was one of the best shade tree car mechanics you could find.
      I admire what my parents did, but it took me until I was nearly 40 to fully appreciate the "greatest generation." They faced 17 years of a poor economy and war, a war that affected our nation greater than any war had to that point and since. All of my grandparents were immigrants, those on my mother's side didn't speak a lick of English when they arrived. As you can tell by my last name, my father's father was German. They didn't face any anti German sentiments during WWI or WWII as they lived in an area in southwest Wisconsin where nearly everyone was a German immigrant. They were some damn good dairy farmers.

      Another American engineer here. FYI it’s not just “Americans”. Even if you use the term “American” properly to define anyone from both North or South America, you’d still be incorrect. My colleagues in Britain still use many imperial measurements which are often times slightly different than SAE measurements of the same name, further complicating things.
      Converting from Metric to SAE is simple, can be estimated in your head quite easily for rough planning and only requires you to remember a few simple conversion factors.
      (Ie. 25.4mm = 1”) For rough estimates, simply drop the .4 and now 25mm = 1” roughly and hopefully anyone with an education should be able to do that math in their head on the fly.

      omg Toy Man, sounds awesome, but don't build the bugger to scale, I don't think the wings on her will produce enough lift at low speeds to control it.. in the real x 15, the wings were designed to give just enough control to land it in a steep glide , and maybe a tiny bit of lift in the ascent phase ( usually an aoa of 70 degrees or more).. then pretty much dead weight at apex of the flight.. notice the vertical stabilizer is similar in area to the wing .. more of a lawn dart than a plane.. though im sure even those stubby little control surfaces had heaps of control at mach 4/5 etc.. while on a speed run.. I've always thought of it as an F104, with a redstone strapped to the back.. (much more complicated, but similar in ways) .. I believe it was Pete knight that said it put 5 to 7 gs sustained acceleration on you, he said an engine quitting on any other aircraft was a cause for concern,, it was cause for relief in the x15...
      xlr 99 at idle setting gave you mach 4 at 100,000 feet.. the thing was on another level .. I spoke to a guy who flew chase close to the end of the program at a seminar at Wright Patterson, he said on drop (at launch) he would light up the j79 's burners to try and keep the thing in sight..utterly moot, the 15 was out of sight in less then ten seconds as soon as the engine was lit.. he was told not to bother wasting fuel.. just planning for one of these flights and having chase and emergency equipment all along the flight path, was a major logistical feat.. it was so much faster than anything they had.. wish you the best in your model , maybe give her bigger wings lol..

    The testing of the "X" engines by Reaction Motors took place daily at Picatinny Arsenal in Northern N.J.. I lived in a small community just to the east of the test site called Lake Telemark. I grew up hearing the warning whistle followed by a roar that was so loud it cracked windows and sidewalks. While playing touch football we would stop until the engine test was over. We could not hear the hike signal. A constant flow of trucks carrying liquid Oxygen tanks passed through our small crossroad a few times a day. It was a way of life. Sneaking up there to watch or sneak around the entire base was always a summer treat. Never got caught. Great history, thanks for the video.

    Slight correction that no one will care about :) at 5:42 the X-15 shown isn't actually equipped with a "ramjet" but what was known as a "Supercharged Ejector Ram Jet" or SERJ engine. It was technically a rocket motor (the "ejector") inside a ramjet duct, (ram jet obviously) which included a powered "fan" (single-stage compressor) that would 'supercharge' (obvious) the ejector-ramjet airflow and could in theory work up to speeds in excess of Mach 6 (free spinning at speeds between Mach 4 and Mach 6) or in later modes being folded up out of the air-stream for higher speed flight. In basic operation the SERJ X-15 could probably have self-flown from the ground being that the SERJ operated as a more 'normal' jet engine at low-speed and altitude with the fan compressing air which was fed into and assisted the intake air-stream of the ejector rocket and used the ramjet as an afterburner system. Once around Mach 2 the fan would be let idle while the engine converted to pure ramjet power to around Mach 5 where the rocket motor would be re-started and push the vehicle to speeds in excess of Mach 6... While the most advanced SERJ concept was to use LH2 and LoX the first flight weight models were to use Hydrogen Peroxided and kerosene and several such motors were built and tested before the program was shut down.

    I hope you do a video on the SR-71 Blackbird. Such a remarkable jet, my favorite by far.

    • @02markcal
      @02markcal 7 лет назад +26

      Over 4,000 missiles were fired at the Blackbird in the 25 years it was flown, but none ever hit it. The Blackbird was just too fast and its evasive tactic was just to speed up until the missile couldn’t keep up with it.
      Its navigation system called “R2-D2” had a sensor so powerful that it could detect up to 61 stars in broad daylight while the plane was still on the ground.
      The plane required a large amount of titanium to be built so the CIA created fake companies around the world to buy metal from the USSR, which was the biggest supplier, as well as the United States’ enemy at that time.
      The plane was covered in over 60 pounds of black paint because the black helped cool down the plane by up to 86 degrees. Traveling at over Mach 3, the plane could hit as high as 1,000 degrees without the black paint dissipating the heat.
      The SR-71 constantly leaked fuel while not in flight due to the contraction of its titanium skin. The tank was designed to expand as it heated up due to air friction. The SR-71 had enough fuel to take off and then get refueled up in the air by a tanker. Even though it leaked fuel, the fuel had such a high flash point that it would not ignite even if it was hit with fire.
      The camera on the Blackbird was so advanced that when it took a photo of a car on the ground that was 80,000 feet below it and the plane traveled at over 2,000 mph, the license plate would be visible in the photo.
      All other planes have either a three minute limit, or five minute limit on that, but you’d be going at full afterburner for an hour, hour and a half.
      It is the fastest planes that ever took flight. The official fastest record it holds is 2,193.13 mph on July 1976.
      It earned its nickname “Blackbird” because of how stealth it was. It was also extremely quiet inside the cockpit, according to pilot Richard Graham. “You could hear a pin drop. The view is spectacular, being able to see the curvature of the Earth and the black space above filled with stars,” he said.
      I agree with you!!

    Many thanks for this and reminding us of the first space plane, technically the Americans were the first to reach space with the X15. I always felt that this concept should have been taken further, the space race and the objective of going to the Moon took over and the X15 was cancelled. They were though, ahead of the game and the space plane concept was rediscovered with the Shuttle, only to be wound up in favour of the space capsule atop a rocket, again. Maybe the space plane will be rediscovered in the future, it is less wasteful and landing like an aircraft is more sophisticated than plummeting to the ground and splashing into the sea, or landing with a thump on dry land, as the Russians still do.

    Your videos are generally superb and well researched. One correction here: N.A.C.A. is generally stated as “the N-A-C-A” not “nacka”.

    Nice video. Lived in Lancaster California 1967. Lots of sonic booms back in the day.

    Great to see this - my dad worked at NAA during the lifetime of this program - not in this area but at the company.

      Yeah I am surprised we aren't seeing that many. Must not be relevant to them since this is more military related and not space. At least not at first.

      Its because they don't pay attention to science.
      The X15 is pure geek porn. So those weiners just don't know about it.
      (I get the urge to yank every time i hear xlr99... the x program aircraft was geek porn supreme. )

      Paul Maggs possibly, I should have been clearer I want like a six or seven DOF set up with a VR helmet. I’ve found some pretty interesting off the shelf platforms but they start at roughly $12K.

    Love your vids, but N.A.C.A. was pronounced En Ay Cee Ay not naca. Just as the RAF was Arr Ay Eff not raff.

    I saw one of these many, many years ago at LAX, sitting off to the side as our plane taxied toward the runway. And, last year I saw the one on display in Washington. One of my all time favorite planes.

    I remember building a model of the X-15 as a kid. It was so cool. It was one of my favorite aircrafts and models that I ever put together. I saw color and B&W pics of it in the newspaper and on a Black & While CRT TV. It was so exciting to read and hear about. I always told my friends about in when I was a kid and as an adult as to how fast it was.

      Zaed zain You could not be more WRONG if you tried!! The X-15 IS an aircraft by every definition of the word!! Merrimack -Webster dictionary defines aircraft as: “ a vehicle (such as an airplane or balloon) for traveling through the air.” The X-15 is an airplane designed to travel through the air, it just uses a rocket engine. IT IS STILL AN AIRCRAFT.

    I'm my eyes. The X-15 is a maned, landable missle.
