The Most Reliable and Versatile Sub-orbital Rockets Ever Made; the Black Brant Sounding Rockets

[@Canteen1107]

The hinterland who’s who intro just hit me with a ton of nostalgia

[@shinjofox]

You are giving me flashbacks to childhood. I can't wait till there is a house hippo video from you.

[@joeblow9657]

Same!!! Also, I just adore house hippos.

[@j.jasonwentworth723]

Thank you for creating this historical video! There are a handful of errors (which don't detract from its value), which I thought I'd point out: The rocket shown (in color) between 8:42 and 8:53, just after exiting the tower launcher at Churchill wasn't a Black Brant, but an Aerobee-Hi or Aerobee 150 (these two rockets were very similar), a 15" diameter, Aerojet General-made, boosted single-stage pressure-fed liquid propellant rocket with a 12.75" diameter solid propellant booster that burned in parallel (note its two sets of fins); the booster fell away after it stopped thrusting. The tower launcher--which was designed to accommodate three-finned rockets--was built at the Churchill Research Range in the mid-1950s, for launching the Aerobee vehicles (but its interior launch rails were adjustable to accommodate rockets of different diameters). The sides of its protruding triangular beam section, above the roof (like a radio tower, but much wider) were originally covered with metal panels--you can see the tower launcher in its "as new" form in Newman Bumstead's article, "Rockets Explore the Air Above Us," in the April 1957 issue of "National Geographic" magazine. (Beginning in the late 1950s, several rounds of the Aerobee 300--an Aerobee 150 topped by a second stage consisting of an 8" diameter AIM-7 Sparrow air-to-air missile solid propellant rocket motor [its frustum--"cut-off cone"--adapter doubled as a vacuum-optimized nozzle skirt extension and as a conical stabilizer, as with the Black Brant IV's second stage]--were launched from the Churchill Range.) Also: The black-and-white, "on-horizontal-launcher" picture (between 8:08 and 8:18) of what is said to be a Black Brant V was actually either a Black Brant IIA (having four fins), or perhaps even--although less likely--a Black Brant I. Incidentally, your narration referred to the PTV as the "Propellant Test Vehicle." Every written reference I've seen said that PTV stood for "Propulsion Test Vehicle," although it is true that the vehicle's purpose was to test the then-new, CARDE-developed CARDEPLEX solid propellant (by the way, the Black Brant I, II, and V motor cases were the same diameter and length--or very nearly the same length--as those of the British Skylark sounding rocket's Raven series of rocket motors), and: In the narration and the screen text, you referred to the CRV7 (I've also seen it written as "CRV-7"--it's short for "Canadian Rocket Vehicle 7") as the "CVR-7." Also, at places in the screen text (such as about the Black Brant 6 and 7), multi-kilometer altitudes were abbreviated as "kms"; in all such expressions (kilometers, grams, kilograms, etc.), the abbreviations--they're actually symbols, as they are also used in other languages, regardless of their alphabets (like "F(x)" and other mathematical symbols)--are always written as singular (12 g, 7.5 kg, 438 mm, 170 km, etc.).

They just used a black Brandt, terrier sounding rocket, launched from Wallops Island about a week ago. ☀️😎🇺🇸☀️

[@CYBERIanEyeCandy]

Pure Awesome... Living in America now and love the wildlife intro and extro... Thank you!

[@PatGilliland]

Wow - I knew of the Black Brant and flew a model version several times as a kid. I didn't know that it was still in use into the 2010s.

[@Roarmeister2]

Still in use TODAY and will be for some time.

[@johnandrews3568]

Another great addition. LOVE LOVE LOVE the Intro-extro bit, lol. Sounds of our youth. :)

[@polyus_studios]

Glad you enjoyed it

[@RME76048]

Very nice documentary. I didn't know that there were so many variants on the BB series. The BB V and BB XII have always been favorites of mine.

[@RME76048]

@@polyus_studios I understand that Bristol Aerospace changed to Chinese-manufactured ammonium perchlorate oh, perhaps ten years ago, and as a result started having problems with nozzle throat erosion rates and other effects that compromised the predictability of performance.

[@Crescent5]

@@polyus_studios am doing a project about it can you please give me good ideas in 1 of your video

[@JasonDykstraMT]

Great video! My grandfather worked at Bristol Aerospace, specialising on rocket nozzles, some of which were used on the Black Brant. It's great to have such an in-depth video about something I knew so little about, and makes me appreciated my grandfather's work even more!

[@weetytoaster1835]

I like the music that plays in the background

[@dogbiscuit1649]

Love it. Thanks. The 2a is my favourite, I have one in my living room window. A model. Not a real one, are you mad!? Happy Christmas.

[@themadscientest]

It is one of the most popular rockets to build models of, it is a great design.

[@stephensheppard3501]

I found this due to building a BB estes model rocket. Looking for detailed pics and info, this documentary absolutely delivered. Thank you :)

Fun fact: the Magellan factory is right next door to a huge hockey arena complex

Nice bit of humor at the end.

Great video. Thanks!

A 98% success rate is astonishing!

[@Havazik]

I just discovered your channel and I'm already a huge fan. That HWW reference gave me massive nostalgia. I don't remember the last time I heard that intro (also the ending was hilarious) Thank you!

[@CULatte]

Nice vid, Black Brant XII launching out of Wallops in Virginia this Friday, 14 May 2021

[@elliottkrieter4640]

Nice video! Love this rocket! I have a BB2 I'm rebuilding after the fins broke off from some mishap and a Vb from a new kit. Both take 38mm motors. Looking forward to launching them at Midwest Power 2020 Oct 31 to Nov 2 in Princton, Il.

Please share back on this comment when your bird 🦅 launches 🚀

[@capturenorth]

nicely done, thanks!

[@JUNEWICK5087]

About to build this rocket for NARAM in Colorado later this year thanks for the history!

[@RocketTCoyote]

I have a 1:5 scale Black Brant II cardstock model converted to fly on 24mm motors. One of several built and flown. Flying model rocket kits of several of the BB series are available.

[@Hartwig870]

Some buddies and I got drunk one night in Churchill and climbed on top of those old launch buildings.

[@GlenKowalchuk]

Back in the 50's my dad worked on the Black Brant rockets. 70 years later here we go again with RedWing being built & launched by Bristol Aerospace/ Magellan to re-purpose the Northern aerospace defence. 👍👍😎 Winnipeg

Goose it!🚀

[@bucheronix]

For comparison purposes, the International Space Station orbits the earth at an altitude of 410 km.

[@robrocksea]

Another reason I cried over IRBM, and ICBM destructions under the SALT and SALT II treaties. All could have been used as sounding rockets or small orbital payload launchers. It could have been a modern day real swords into plowshares program. With little International oversite and observation.

[@IgotQuestions.]

How much can cost one that climb at 150km ? Can anybody buy it ?

[@IgotQuestions.]

@@polyus_studios thanks

[@spacewolfjr]

I remember first hearing about the Black Brant due to the 1995 nuclear missile scare

[@uhfnutbar1]

Canadian built and a source of pride Canadian`s :) Tell me if you recognize the opening music from parks and rec TV commercials

[@jesseraina1614]

You need to create a video about canadas Bomarc Nuclear Surface To air Missiles, bomarc and earlier version also canadas mobile surface to surface nuclear missile deployed in west Germany. During the cold war. And canadas involvement with American nuclear heavy bombers at Goosebay Northbay etc

[@jacobmalin1338]

I went to Churchill recently and have footage of the old missile range and facilities. If someone is interested i can upload the videos on youtube.

[@polyus_studios]

Definitely!

Sounding Rockets are not spin stabilized the way that bullets are. Sounding Rockets spin to average out asymmetries such as off axis thrust or one sided aerodynamic protuberances
