    FSX: The 1940 Fokker T.5 bomber

    Hi everybody,

    Thought I might post some WIP stuff here about my next project: the Fokker T.5 bomber for FSX. Work is still being done on the D.21, keep that in mind.

    Anyway, let me tell you guys the complete outline of this project.
    Back in September, I started research for a T.5, whether it should be possible to create one for FSX or not. I got loads of information (but still lacking a lot, as always) and decided to continue.
    Then I came in touch with mr. Wim Anceaux (www.anceaux.nl). He is a relative of W.F. Anceaux, who was the pilot of the T.5 that made a mission to the bridges near Moerdijk and Dordrecht in May 1940, in order to stop the German invasion. The date: 13th of May, 1940. The bombing mission however failed and even the bomber was shot down, killing its entire crew. Actually, they were prepared for this on the airfield, since circumstances were criticial. Another well-known crewmember of this mission is Ben Swagerman. One C-130 Hercules is named after him.

    Mr. Wim Anceaux has organised two memorials for this particular crash in the past, but wants to organise a bigger one in May 2015. We had some contact and I came up with the idea to produce a video of the FSX T.5, which should be shown on this memorial (13-5-2015). Since I don't have the smallest experience in this video-producing, I eventually contacted Jonah (JRSchiphol, YT: https://www.youtube.com/channel/UC7g...86yUxsilI0nEDg). He will create the video for the memorial.

    To get things done before May, I'll create the exterior model first, also because the VC will take much much much longer time. I'm quite excited about this project and I hope for succes!

    Hope I made things clear!

    Now for the pictures. I've posted some on my blog and on other forums, so I'll start with the current status. There they are.

    Looks like you are off to a good start, Daan!

    And for those who've never heard of the T.5 before (I can image more than a few..), here's how it looked:

    Intel i7-7770K Kaby Lake @4.2Ghz, Cooler Master 212 Evo, 16 Gb Corsair Vengeance DDR4 RAM, Asus ROG Strix Z270H motherboard, Asus RTX 2070 Turbo 8Gb, Cooler Master 700 Watt PSU, Windows 10 64-bit.

    Looks very promising already! The shape is very recognisable.

    Performance of the T.V was in the same range as the Handley-Page Hampden. Technically an interesting aircraft as it had 2 cockpits. So instead of one VC this model will most probably need 2 VCs

    Cheers,
    Huub

    Great initiative! Best of luck creating this beautiful plane! Looks like Bristol Pegasus powered plane, right ?

    You're correct about the engines Lucas. Bristol engines were the only engines available for the Dutch so close before the war.
    As the Dutch didn't produce their own engines, the were depending on the countries, who were already preparing for the war. Most sophisticated engine were already used for their own war industrie.

    Even though it's a bit like a shoebox with wings, I've always like the way this thing looks...

    looks promising!
    2 cockpits?

    Yes it had two cockpits, or perhaps I should say "steering cabins" (stuurhutten). The first cockpit is where you expect to find it, but the aircraft could also be flown from the top gunners position.
    As you can see on the picture from the model below the first part from the top gunners position was transparent and could be opened as windshield.

    Cheers,

    Thanks for the kind words guys!

    Yeah, in cockpit arrangement, the T.5 had a rather different configuration. Firstly, though it seems to be a normal cockpit with two seats, the pilot sits actually at the left side, with his panel at the right side of the cockpit. Below that panel, there is a kind of walkway, between the centre section and the bombardiers station. I expect this baby will have 5 VCs . A cockpit, a bombardiers station (say nose section), a top gunner bathtub , a radio/navigator/waistgunner position and a tail gunner. More interesting is the fact that everything was connected, no real closed sections, so it will be a huge VC and a challenge to keep it frame-rate friendly. Well, we'll see first finish the exterior.

    Ah, and another feature, which I SHOULD include: the communication and warning horns. These Bosch horns were located above/behind the pilot and they sound like...

    1) More materials = more drag on performance.
    2) Don't bust 65536 vertices per material.
    3) If it can't be seen without effort, it doesn't need to be detailed.

    Keep that in mind and you'll be fine.

    Thanks Bjoern, I'll keep it in mind!

    Thank you, Huub. Same situation was in my country, except there was an engine factory, but the authorites decided to construct Bristol engines under license in late 20's/early30's. So, we had Jupiter, Mercury and Pegasus installed in our designs.

    Like I wrote before, I will keep my fingers crossed for the project. I love the designs from the 30's, made before the WW2 and this is going to be a fantastic add-on.

    By the way - are there any original documents related to this plane which survived ? I mean - technical description, pilot's manual, etc. ? Just curious.

    There are still some original documents available, for instance the pilot's handbook, but unfortunately hardly any original drawings. In the Crash museum, where the wreck of the D-XXI is on display, they have some parts from the excavated T-Vs.

    Great start to a very interesting aircraft. Good luck
    with this project,so far looking good.

    Regards Anthin.

    As usual, we have to create the old Fokkers from basic drawings, photographs and, with a bit of luck, an official document

    Thanks for the enthusiasm!

    Tonight, I made a basic start of the rear section, which was made of steel tubing trusses, with fabric covered formers and stringers. Typically the mixed construction that Fokker used in those days.



    And another shot with a simple start of the wings. I've obtained both airfoil data and wind tunnel test data of a official T.5 model. So that's quite nice

    Looks nice Daan! As soon as you add the cone for the tailgunner you have a start for a G-1 *big wink*

    Cheers,

    Thanks Huub! Yes, and remember, I've even got two Mercury's here at home

    Please note I mean virtual Mercury's The D.21 has a Mercury, so in fact I have an infinite number of them...

    Some further progress.

    I eventually remade the entire tail section. It is now right according to pictures, so I started to add the waist windows. Just in front of the right window, there's a door (with built-in stairs!) but not yet added. I'm still working in the Mirror Modifier.



    And there's the second pilot/top gunner position. The first pilot sat in the cockpit, the second sat in the bathtube at the back of the airplane, with a sliding roof and hydraulically operated windscreen. His job could be either flying forward or firing backward, he even had two seats.



    Though I've recieved bulks of information, bulks of information are still missing either. There are no detail photographs of both the exterior of cockpit section and the roof... Anyway, this causes my model to be not fully accurate...

    Making great progress Daan!

    Thank you Cees!

    I've played a bit more with this bird: I added wings. Since I have both the airfoil data and windtunnel testing report (of a 1:20 model, not 1:1) this was a fairly easy job. I spend some more time on the rounded wingtips, I still find them difficult to model (googling rounded wingtips returns shoes...). I did them better than on the D.21 though, IMHO.
    Prolly I'll throw the wing geometry through AVL, for fun and maybe it has use... AVL is software for Computational Fluid Dynamics: AVL

    Next steps are the engines + nacelles and the vertical stabilizer. The roof hatch has to be redone (according to specialists at the Dutch forum) and I need to add the tail cone turret.

    Wow the very secret Fokker T.V glider bomber. A predecessor of the stealth bomber

    But it looks good Dan and you are making progress quite fast.

    Cheers,
    Huub
