About this Plan

Boeing B-47. Catapult launch glider, profile model.

Quote: "A 19 inch span profile scale, catapult launched glider, with ultra simple construction. Boeing B-47 by Jack Arnould.

AFTER FLYING your umpteen channel, high powered, flying bank roll through some hairy manoeuvres, COOL IT, relax and have some low pressure fun! Build this no channel, low cost, high start glider - just think, no engine noise, no radio problems, just plain old fun - but don't let your kids see it or you may never get your hands on it again! I know this to be true as I have four girls and this is the first of my many models that they have taken any great interest in. Now they are actually disappointed if we don't go out and fly it.

The plane is a 1/72 profile scale model of the Boeing B-47, the world's first all-jet high speed bomber and the mainstay of SAC for many years, until replaced by the B-52.

Construction is quite simple and straightforward, and uses medium hard balsa throughout. First cut the fuselage from 1/4 in sheet, taking great care with the slots for the wing and tailplane. Keep the knife blade vertical and cut from both sides to avoid the slots sloping from one side to the other of the fuselage. Cut the hole for the ballast and then cement the 1/32 in ply nose doublers in place. Next cut the wings and tail surfaces from 1/8 in sheet and sand to section - also cutting the engines from the same sheet. Leave these parts with a square section except for the inner engine supports, which should be streamlined. The 1/16 in square strips inset into the leading edges of the engine supports are to stop the engines shearing off in a moderately hard landing; in a really heavy landing they will let go and save the wings from damage.

When all the individual parts are ready, mark out the control surfaces, cockpit cover, windows, and other lines shown on the plan with a felt tipped pen. Join the wing halves, not forgetting to put in the anhedral. When the joint is dry, re-enforce it with a inch wide strip of silk cemented to both sides..."

    ScaleType: This (oz4622) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Boeing_B-47_Stratojet
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

Spent ages trying to get this to glide properly. Ended up cutting the wing in half and remaking with dihedral. Still not great. The youngling (5yo) picked it for its good looks, now he's convinced he is no good at flying planes. I'm going to buy more balsa and build something else as fast as I can before he gives up. Maybe someone else might have more luck. Vids or it didn't happen ;-)

Seeing Dean's problems with the B-47 glider, I wonder if a greater degree of ANHEDRAL might help? Glancing through my Putnam's 'Boeing' book, the full size certainly seem to have a fair amount of 'wingtip draggin' when on the ground. Having had the plan 'kicking around' all those years, I suppose I ought to build one myself! Cheers.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
