UAV project, Help needed

[prasgane 0]

I am currently attending college to get a degree in electrical and electronic engineering. I have decided to build a UAV for my project. I have gone through a lot of sites and papers on this topic, but I am not able to get a clear idea on how to start the project and what are the most basic components that are required to build a UAV. So could someone help me with this?

There are many types of UAV, what type, size, abiliy. How much off the shelf do you want, how much do you want to make. what experiance do you have in flying, electronics, model building?

Hey,

Thank for replying. I was looking at more of a long range high altitude UAV. The size is not yet decided. I dont have much experience in flying or making uav. The designing is done by an aerospace engineering.

You will probably run into problems with regulations if want long range or high altitude, both are also pushing the limits of most amature UAVs.

oh, and what are the different materials we could use for making the outer shell of the uav?? like is it a composite or something??

[prasgane 0]

and about the regulations, we dont have any regulations for flying uavs in india i guess. I was going through the internet and I didnt find any such regulations. It doesnt look like they are going to make any.

[Terry 5]

You can make the airframe from anything depending on size. If you dont know much about aircraft design then maybe just buy a model plane kit of your required size and work on getting the electronics right.

Spektrum DX8 2.4GHz require which telemetry either 2.4 GHz or 900 MHz?

[jeevanreddy 0]

hello sir,

im in to uav project and got struck in choosing the frequency for my telemetry.my rc set is of 2.4ghz,fpv is 900mhz and cant decide abt telemetry frequency!

please help me!

thankyou

[Terry 5]

Its normal to use your video downlink audio channel to receive data from your aircraft. If you need to send data to the aircraft then lots of 2.4 systems will work ok with 2.4 rc. If not then a UHF link is common.

sorry sir i didnt get you!

can u be more clear?

actually im using APM2.5 on my uav, so telemetry is must for mission planning.which frequency do u think is best for 1km range which can penetrate into small cardboard rooms? please help me!

thanks in advance

[Terry 5]

I dont understand small cardboard rooms but I think UHF 433Mhz would suit your needs.

thankyou for ur reply sir!

cardboard rooms means a small building made of wood with four rooms through which our uav should pass and cover the activities going on there

can i get 1kim range with 433mhz telemetry system without any glitch?

if so can u suggest me a set which u have an idea?

thankyou

I cant say you will get 1km range through wood as it is far too complicated to work out. All I can say is that it would be a good choice to start your testing. I also have no experience with the apm2.5 so you will have to find a suitable modem from the information you have.

This hobby is all about testing out your ideas and making your own equipment where possable even if it has got a bit plug and play in recent years.

thankyou for your reply sir. sir actually wood means its plywood of thickness around 1.5cm.do you think i can do this usibg 433mhz?

infact i will start testing as soon as i receive my sets!

thankyou

I think you will be fine, have fun.
