need help in my research

[ttagroup]

Hi
I'm Student in Kerven University in UK
and I'm doing a research in Airplane Field , so my study needs from me to build a R/C Model and study things over it , but before I start my building for the model , I need answers to some questions in that field , so I wish if any can help me and answer my question , or at least gives me the resources that I will find my answers there , and I will add his name to my research as a reference if he help me in anything , my questions is :

1) if I wanna my plain to hold a load of 10kG weight , what it should be :
a) The suitable scale / size for the model to hold that pay load and what it will be the approximate weight of it
b) what is the maximum range of fly for such a model ? can it fly for more than 20 m for example ? and what kind of equipments I need for that to keep control of it ?
c) what is the suitable engine for such kind of plane model ? and what is the maximum speed that it can be fly in ?

2) if I have the total weight of the plane , how I can calculate that minimum speed for it that can keep it fly without go down ?

I will be very thanks if any can help me to find answers on these questions , or at least to give me good resources to find what I want , he will help me altos in my study

1) if I wanna my plain to hold a load of 10kG weight , what it should be :
.
This is a substantial load.
The plane will be large.
'

a) The suitable scale / size for the model to hold that pay load and what it will be the approximate weight of it
.
Anticipate an airframe weight ready-to-fly, without the payload, of 10 kg.
.

b) what is the maximum range of fly for such a model ? can it fly for more than 20 m for example ? and what kind of equipments I need for that to keep control of it ?
.
Range is limited by the fuel on board. However, control is limited to how far away the plane can be seen. The radio can control the plane after it has flown out of sight. This size plane can probably be controlled at 1/2 mile, possibly a bit further with optical aid.
.

c) what is the suitable engine for such kind of plane model ? and what is the maximum speed that it can be fly in ?

.
A large gas motor.. 25 cc minimum. Max speed, maybe 60 mph.
.

2) if I have the total weight of the plane , how I can calculate that minimum speed for it that can keep it fly without go down ?
.
Yes. But. Flying slowly is dangerous. Stall/crash waits those who fly slowly.
.


I will be very thanks if any can help me to find answers on these questions , or at least to give me good resources to find what I want , he will help me altos in my study
.
This project is beyond your capabilities.

Odd, I can't find any reference at all to such a place as Kerven University in the UK. And uni students in this country usually have a slightly better grasp of the language. I wonder who this person really is.

In this post 9/11 era...
The language situation struck me also.

The model(?) could be controlled by a following car, thus making its effective range much greater, then it is truly limited by its fuel storage capacity. This has been done quite a few times in long distance record attempts in Australia, its even been done from a boat in a successful long distance over-water record attempt between Fremantle and Rottnest island in Western Australia some years ago.


Is it possible that 'Kerven' was a typo considering the language barrier? There are quite a few foreigners studying in Australian universities, I would assume it is a similar case in the UK?.

Maybe 'ttagroup' could mean 'Turnban'd Terrorists Attack group'?
Tho I doubt it very much.

[ttagroup]

Well Guys nice to hear from you about 9/11

Actually yes , I'm not a British guy , I'm from Turkia , and study in UK , well , I don't know that 9/11 still scare you that much , and exist in front of your eyes what ever you go ...

any way , it is not our subject , actually why I ask about the maximum distance that can a plain arrive , because one of our study phases to fix a camera on the model that will direct it to land safely in the other side , so if I will use that Radio , what is the maximum range for it ? same for the fuel ?

Sparky Paul , thanks for your answers but , that 10KG is the equipments weight that will be on the model (GPS , Camera , ... ) , so can u tell me where I can find model to hold that weight , and what is the size of it , it should be ?
and how I can calculate the minimum speed that the plain should be in to not Stall/crash ?

MrBungle , I like your ttagroup meaning , keep it up man , and thanks for the information , can you provide me with more about that experiment ?

steve lewin , man dont worry , I'm not bin laden , and I hate that guy more than what u do .

Guys , I want you to understand one thing here , I'm not here for fun , it is study that it will be part of my research , so if some one want help , I will be very thanks for him/her , but no need to start imagine things always as 9/11 , that is really a Joke , and make me lol ....

[MrBungle]

ttagroup,

Sorry I have no real usefull details about those record attempts as they happened in the 1980's and the magazines
that featured the stories are either lost or thrown away in the rubbish.

The only information I can find is a referance to another world long distance record set in Australia on May 18th 1994, where a model aircraft flew 493km(306 miles) non-stop(no landing, no re-fueling). The plane was piloted from a car, it had a 7 foot wingspan and weight of 6.5lbs (3kg) using an O.S. Max-46SF engine (7.5cc) swinging a 14x8 propellor at 4,800rpm and using Hitec radio gear (there ya go Mike@Hitec!!), which is no where near big enough to carry your 10kg payload.

Sorry I couldn't be any more help than this, but it shows that VERY long distances can be covered with these planes and a pilot following the plane in a car etc.

Oh, There was no information on the amount of fuel needed or the size of the fueltank.
Oh #2, The Fremantle to Rottnest island flight was 19km (12miles) and lasted appox. 35mins, obviously the limiting factor here was the speed of the boat carrying the pilot as there were 2meter (7 foot) sea's at the time!

At UC Davis, there is an aeronautical engineering department that takes students along with faculty and designs airplanes to compete in load carrying contests similar to what you've described. There have also been articles published in Model Aviation on these events- contact the AMA library.

Also in the UK, there is a shop called Just Engines where they are very knowledgable about engines and have helped modelers compete in duration events.

Sorry ttagroup, but your post is very suspect. Yes 9/11 is still with us, it's not in front of our eyes all the time as you say, but it is always in the back of our mind. There have been additional attempts since 9/11 and we all know there will be more, it's not over yet. We quickly become suspicious of anything that doesn't fit in with the norm.

The request for info from someone with no experience, on building a plane that will carry 10kg, how big it will be, and how far it will fly raises a lot of red flags, regardless of your stated intentions. Add to that the post from Steve that the University you claim to attend doesn't exist and, well........ I don't know about everyone else but at this point it just looks too much like a potential weapon to me.

I didn't think you were Bin Laden, just a troll making poor jokes.

If I'm wrong just just let us know your name, where in the UK you are studying and what course you are taking and I'm sure we'll be glad to help. Since there is an annual challenge in the UK to build a load carrying plane you should be able to get in touch with the other universities who already do this sort of thing through your college contacts. None of them managed 10Kg this year but the rules restrict their engine size.

Glad I'm not the only one who found this post suspect. Its sad that we now think like this, but its our new reality. The fact that our friend says he is an Aero student but does not know how to calculate stall speed is somewhat surprising to say the least. I did the AMA competition in school and without any resources like this. Part of me really wants to help out, yet two thoughts prevent me 1) as mentioned, looks suspect 2) if he is indeed an aerostudent, these are basic questions that he should be able to answer for himself by simply cracking open a text book and some R/C literature (such as hp of 40 and 60 sized engines).

I usually give people the benifit of the doubt and am about the furthest this from a conspiracy theorist, but my spidey senses are off the charts on this one.

A GPS and camera can be added for only a few ounces in weight. So what is the remaining 10KG payload?

[ttagroup]

Guys
First of all who told u that I'm Aero student , I'm a CS Student in Kele University that we call it kerfan (for the guys who ask about the University)

Gerald , well GPS , Camera weight is 4.7 KG and the rest of equipments is for GIS and Control Unit , we are doing kind of A/I system on plains , may be it is new on people that deal with models for fun only , any way it is not my subject now

well , good to hear that there are competition in that fields in UK , any more information about that ?
I just wanna say it again , who wanna help again , he will be very thanks , we are students that do something useful not playing around , and we will find what we need , it is not that much difficult . I deal with all ppl here in respect , I like your hobby , and I expect the guys in that hobby are open mind . for that I put my post here , but it seems I was mistaken

Thanks Again for all guys who help (Sparky Paul , MrBungle , Megowcoupe , ...) and for guys who half of them wanna help , don't worry I appreciate it , and for the rest of guys , really nice to know you and how you live after 9/11 ;) , but thanks any more

my e-mails is : ttagroup@postmaster.co.uk , for ppl who wanna keep in contact

[Megowcoupe]

In hindsight, I wish I'd never responded to this post in the first place.

John,- if you really are interested in soliciting help from others, a more forthright and informative approach would be called for. It also wouldn't hurt to take more time on your posts or get someone with a better command of the language to help.

Sam

[steve lewin]

And guess what, there's no UK university called Kele either (and if there was why would you call it Kerfan ?). Also the university term doesn't start for several weeks yet. And that email address is a freebie webmail site (a bit like Hotmail).

I don't know what this person is playing at but he's certainly not being anything like straight with us. I'm having nothing to do with him.

Steve

[ttagroup]

well , I should not reply , it not necessary to proof who is me , but only for people who wanna know the truth .

Steve it seems u r far away from the educated environment in UK for many reasons , 1) it is keele Univ , I drop an E , and it is not by mistaken , believe me ;) , and ask the students there why we call it kerfan ...
2) u want us to stop working on our research when the study off , we will be good researchers when we do that :D

now will you stop this joke , what do u want from student like me , to pay for e-mail account before I talk with any one .

ok Guys , I got what I want , so it is better to block this post

Thanks

From their website:

"Keele is centrally located within the UK and enjoys excellent communication links for all types of travel. The University is situated two miles west of Newcastle-under-Lyme on the A525 road to Whitchurch, Nantwich and Crewe. "

To the poster:

Your ten kilo payload is way out of your reach. A gps/camera setup can be done at several ounces. Many could help you with this task but frankly you give me the willies.

Part of learning good engineering practice is setting realistic goals. You could easily design a machiene to throw an egg several hundred meters. Designing one to throw an egg several miles would be too much for an undergraduate with a limited budget. Yet not impossible from an engineering perspective.

Kirfane -- (source unknown) Refers to the White-Hilted-Knife that is used by Witches for cutting. This knife is often confused with and referred to by the term and knife 'Bolline'.

It is interesting to note that the Sikhs possess a small sacred knife called a kirpan which the hide in their turban and which may be related to the Kirfane. Kirfan is Anglo- Saxon for "to cut" and is pronounced 'kar-fahn'.

Other spellings are curfain, curfane, kerfain, kerfan, kerfin, and is pronounced 'kerr-faign' or 'kar-fahn'' or 'ker-fahn'. Also Kerfan, Kerfain and Kerfin.

[U2Steve]

Hmmm... Is this where "kerf", the cut made by a saw, comes from?

We now rejoin our regularly scheduled thread...

[DBCherry]

Other spellings are curfain, curfane, kerfain, kerfan, Hm-m-m-m, this just gets curiouser and curiouser.
Gotta' admit that you and your post(s) sound very suspicious.

Why won't you post you name?

Has the Department of Homeland Security been notified?

[Ensignnolo]

CNN had some video on their webpage Tuesday about some Remote Control Airplanes found in Colombia that looked like they were set up to be weapons, but I was unable to access the appropriate website. Does anyone recall any other coverage?

If the appropriate authorities have not been notified, I'd be happy to do it.

[Ensignnolo]

I found an article on the planes, here's the text:

Colombian army seizes toy airplane 'bombers'

Colombian troops have seized nine toy airplanes that rebels were planning to use to launch remote control attacks, the army says.

The model airplanes were found during an early morning raid on two camps used by the Revolutionary Armed Forces of Colombia, or FARC.

The camps were discovered near the town of Arauquita, 250 miles north east of Bogota.

General Martin Orlando Carreno said: "We have information that these planes were going to be loaded with explosives."

He says rebels could have potentially used the planes to attack an important oil field in the area.

The rebels have never before used model airplanes to carry explosives but earlier this year the army destroyed a real plane that officials said was already loaded with bombs. It was found in the same region.

[cwatters]

ttagroup if you are really interested...

You should write to the BMFA at http://www.bmfa.org/ and ask them if they can help.

I believe there have been "Payload competitions" in the UK. Some of the teams that entered came from universities. Ask the BMFA if they can give you the address of past competition organisers.

[cwatters]

Oh by the way...

[Sparky Paul]

Keele University deals in medicine if I read their interests correctly.
The tie-in with remotely guided airplanes is relatively tenuous.

Chances are that we are being visited by a troll, not a terrorist.

Regardless, I did in fact notify the FBI shortly after this thread was brought to my attention.
