VTOL - Vertical Take Off & Landing




http://www.zap16.com/images/cdg06-05%20Boeing%20747-437%20VT-ESO%20Air%20India.jpg
61 inch Boeing 747-300 electric ducted edition build log
plane dimensions = fuse length =  61 inches
                                              wingspan    =  51 inches

hey guys finally a bit of time to share about all the action thats going on here.

started this project after being inspired by an ex-747 pilot (my neighbour uncle)

first of hats off to brett jones for designing this plan as scale and good as possible

thank you

http://www.parkjets.com/747/

well ok i have done a ton of mods but none to the basic model. the model as it is in the plans doesnot have polyhedral. other than that i have added landing gears plywood reinforcements and also the better edf mounts.

and yes all plywood attachments were done by 5-min epoxy. (very tough for an impatient guy like me.


electronics

servos - futaba standard ball bearing servos *4
            sanwa standard servos * 4 = flaps and speed brakes
            futaba standard one more for the massive landing gear retract which i one unique thing i designed

radio -  sanwa/airtronics rds 8000 8 channel 2.4 ghz radio

battery pack  -  2* turnigy 3s 11.1v 30c 2600 mAh lipo's

edf's  -    70mm * 4 edfs http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=7887

had three so planning to use two of them here for the first test flight

for first flight the rest two pods will be left empty anyways the plans suggest the weight would be about 1.5 kgs but i am giving it extra power

after the first flight i will put in the rest two edf's which i have ordered from hobbycity for more scaleness

ESC's - 45 amp * 4

thats about all i am about to use here

build part I : wing

first off decided to finish the wing as it would be finished faster

day 1 - finished building the tiled plan from 21 pages of a4 size paper

day 2 - finished the two wing halves with ribs and plywood supports

day 3 - today finished joining the two wings with plywood strips and epoxy

also today i ordered 5 sheets each of 2mm and 3mm depron from pune and will probably get them by tomorrow or day after

and will finish sheeting the wing to get the airfoil and just about finish the wing oh and also plot the flaps, speed brake and aileron servo position and possible hing everything

so looking forward to finish the wing by day -5

following are the pics which i took throughout the build process here they are

hope you like them and please suggest i need all of it i can get

and look at the last pic where the wing nearly dwarfs my electric guitar

VTOL - Vertical Take Off & Landing



Build part II : the fuse

ok guys yesterday i burned the midnight oil and finished templating the fuselage a4 sheets that would form the full fuselage

it took me 3 hours

24 pages of a4 size sheets first of all margins traced and cut and then all of them were stuck together

if you think the wing was big wait until you see the fuse you will be blown away

alright how could you guys believe me staying off the 747 during my holidays  Grin Grin Grin Grin Grin Grin Grin Grin Grin Grin Grin Grin Grin Grin Grin

today i finished a lot of work i mean a ton of it

and yes this is day 4

Build part II : the fuselage (continued)

the upper half of the fuse is just about done

with all sheeting and everything the hump on the 747's fuse is the only sheeting part left

actually the hump is done but the end of the hump to the start of the straight section of the upper fuse is left to be sheeted

this is the part which i believe makes a 747 a 747

alright leaving to see the ipl match

here are the pics enjoy!!!

oh i have also yet to do the nose cone

and i have also just fitted a plywood strip below the fuse it is held by 3 drops of hot gule until i make proper incisions for it under the fuse

this was for the straightness of the fuse while sheeting

I suggest not to use hot glue too much, it will unnecessary increase the weight....and it will be difficult to sand also.....

yes actually it is not properly fitted into place now it is done all straight and square

I suggest not to use hot glue too much, it will unnecessary increase the weight....and it will be difficult to sand also.....

sorry sandeep uncle only place you i have noticeably use hot glue is the nose are as it had to be sheeted with strips of depron and i could not find anything more instant than that epoxy is used everywhere else.

i know the weight issue is a big one but i believe i will be within the range

the plane truly is big and every part is of course big

please everybody be there at airoli on this sunday as i probably will be glide testing this model and i need a lot lot lot of help.

so please be there

You Rock Subbu!! the fold on the fuse is real smooth ! Depron ain't ? what thick ?

Why didn't you use high density Thermocol for the hump ? they are easy to carve and sand to give much smoother shape. You could have scooped the block from inside to reduce weight afterwards.

Keep it posted. With 1 Plane (F-22) ready, one 70%(BLU Baby with L19 Birddog trim) and one in cut pieces (3DBatix Extra 330S), I feel its very tiring to write a build thread. Ya I can blabber 10 times on unrelated topics...

yes i am a depron guy and that sheeting is 3 mm depron

high desity thermocol is something i had thought of earlier but then availability and less experience with them made me go with depron also lack of a hot wire cutter as you get perfect shapes with that hot wire on a high density foam block.

hire me as your forum poster i will charge you only 1 plane per thread  Grin Grin Grin Grin Grin Grin Grin Grin Grin

anyways i love this rcindia forum as after pramod bhaiya and sai uncle rcindia was the first sort of any help and way to discuss with other fellow members and it is from here i found a ton of friends and hence love to post here and let everyone know what i am building or even help others

Subbu Its really great, keep it up. Me too planning a BIG guy for my next project, but I think I go for Airbus 380 or that sort.

But subbu, loose so much weight for some big things like this. Dont use hotglue too much, you cant sand it later and it weighs too much. Go for fevicol SH like white glue instead. It takes time to set but will be very light. You need clips while letting it to set.

Thats for now, CANT WAIT TO SEE IT FLYING!

VTOL - Vertical Take Off & Landing



finally my boeing 747 took to the air it was the primary cg and level flight test for a record 12 to 15 seconds.

gaurav bhaiya's airbus 318 also flew beautifully

before the launch the landing gear came off and hence was hand launched. also the plane was tail heavy but the downthrust of edf made the mammoth stable. and would you beleive it it needed no trimming on the control surfaces

for me and gaurav bhaiya the flight was an entry into airliners.

todays takeoff setup

2 70 mm ducted fans at full throttle

flaps 30 degrees

2200 mah battery

and rds 8000

and the servos mentioned previously

now alright you guys are hungry for video and pics

and the good thing is that the video and photo's were taken

but it will take till today evening as gaurav bhaiya shot it and has to send it to me

now that the model has proved its airworthiness the model is being rebuilt to get a lighter model made of lighter materials.

todays flight's description

gaurav bhaiya did a running throw and the plane took off and i kept it level though it was descending as the plane was massively underpowered. after flying for approximately 10 feet i gave in elevator input and the plane ascended and due to the underpowered set up (due to just 2 ducted fans actual one has four) the plane stalled in mid air and landed safely with a bit of chipped depron in the nose area  -  so it is reasonable to expect the less power and all you guys were right the model was over 2 kg possibly my hot glueing habbit added a few hundred grams.

now just disassembling each section to be rebuilt lighter in weight using balsa and carbon and also a proper landing gear

anyway this models first flight gave me enough confidence that the prototype -2 (or the final one) will fly .

subbu

ps

we had the ex 747 pilot uncle too at the field

and a very very uneventful event which if disclosed could put my future planes in danger as

the person has told me that i post that pic he will shoot down every plane i fly
 
expect the video by 7 or 8  pm depending on when gaurav bhaiya sends them to me

These EDFs X 2 provide 1.7 KG of thrust. Wasnt it not enough for 2kg plane? I still doubt. What battery did u use? 2200 X1 or 2200 X 2?

coz 2200 X 20C = 44 amps. 2 EDFs = 70+ amps. Hope battery not a bottle neck.  Head Scratching If you used 1 battery then you are not getting even 1kg thrust.

The efficiency of EDFs would be well affected if there is not enough a duct.

the ducting was enough anwar bhaiya also i had the intake rings too

and hey vinay bhaiya yes i used one 2650 mah 30c discharge  battery and possibly i got close to 1.4 or 1.5 kg of thrust or more

(sorry i will change the first post as i forgot that it was a 2650 30c and battery not my slowsticks 2200 mAh 30c battery)

as my models weight was over 2kg possibly over 2.5 as i had used nearly 500 gm of hot glue and since then i have ditched my glue gun and bought a ton of 5 min epoxy

any more questions feel free to ask

Great to see it fly !  Thumbs Up

But as we had suspected, it seems to have turned out to be underpowered ?

landed safely with a bit of chipped depron in the nose area

Oops.. Forgot about that :-)

So when r u putting the other 2 EDFs in? And do you have separate ailerons and flaps or have u mixed in the flaps?

Keep up the good work man.. u rock  Salute

actually the other two ducts are coming from hc and am waiting for them

and yes for such a big size plane we always prefer different flaps and ailerons 

on many trainer planes the above flaperon set up would work but for commercial airliner the flaps being seperate are very important

as their positions are different and worl too

if you go in and use the change of pressure caused by them over the wing and also if you try applying the lift formula you will find out the reason of them being far away from each other

oh how i know it is

the neighbour pilot uncle taught me about the lift formula and all about it

we all know about lift thrust weight and drag

but he also taught me the role of  the 2 couples acting on the plane that is lift wight ,thrust drag couples

subbu

ps

he also taught me why the control surfaces fluterred

http://en.wikipedia.org/wiki/Lift_%28force%29 read through this completely

i could not find anything better

the formula of lift coefficient is at the end

anyways you cannot get better detailed knowledge than a pilot with more than 30 years of flying experience   Grin Grin Grin

where did you get  the plan from? i plan to construct something like this... i will learn from your mistakes... and what is the range?

you can even use an onboard camera...if there is room for one

Learning to Fly



Subbu,

I really missed out on this thread.....

Its a lovely build and I can imagine the hard work that has gone in. I love scratch building and am always eager to see the work of others as well. This one is a real beauty.

Good work. Keep it up.

hi topalle as spitfire has answered the first part of your query i shall begin with the next part.

my cardinal mistakes were namely two

Underpowered aircraft - partly due to a heavier (than anticipated) aircraft and partly due to the absence of the other two EDF's

Landing gears - though this plane glides really well landing gears would have enabled be to climb out at a more faster speed helping me avoid the mild stall as seen in the above video.

there is enough room to mount literally anything inside the 747. but the sheer size of the beauty made us forget all about on board camera's or any other additions onto the aircraft. but as i said with enough power you may even mount a dslr into the aircraft (that might just be overkill).  Wink

thank you for the kind words pankaj
