Do you have a logo?

do you know anything about aerodynamics, airplanes in general, or even engineering in general?

>>1007014

no anon, i'm not a jew, if this is something new then I want to share it with the world kinda like freeware or whatever linux fags talk about, plus if someone else makes it then it does a few things for me, 1. I don't have to develop this shit further on my own and 2. the ones that others do develop will likely be of a higher quality and since it isn't copyrighted then there will be many producers and thus keeping prices low

everyone wins

>>1007019

just very basic shit I learned last night, this model is of course for a small airplane (ie; where I could take small electrical and mechanical bits and create a mechanical flap)

>>1007022

im sure the random information you gathered in one night is accurate

>>1007024

dude im just trying to have an airplane thread and share an idea that I thought was neat and plausible

what point are you trying to make?

>"that your a faggot TOP KEK lel"

>>1007024

>>1007025

Please don't make threads unless they're about OS shitflinging

>>1007026

aerospace technology is still technology

I think your mechanism would have weight issues

or if it were made light enough, reliability issues.

The use of notches on the rod would mean the rod has highest strength only at certain sections along its length. Replace it with a screw thread rod thingy like in a bench vise to normalize strength along the rod, increasing reliability.

This mechanism is for adjustable wing angle, correct? A gurney flap with adjustable position would have a simpler and lighter mechanism while doing mostly the same thing.

>>1007039

The idea about the vise screw seems viable, however I don't think a gurney flap is what this would be used for, I envisioned this particular setup for landing flaps and possibly ailerons depending on how fast it can extend and retract.

One thing that a search doesn't bring up is how the flaps work on model planes

>>1007042

From some quick searches, model plane flaps seem to be controlled by servo motors. Most electrical motors can be made to run faster with more voltage, so no actuation speed concerns are apparent.

>airplane

>air

>plane

Bahahaha! American is a fucking goofy corruption of English.

>I'm smelly from doing airbics, I'd best use some airsol.

>>1007087

as simple as that would be i'm looking for something stronger and more durable

here are a couple of points im trying to fulfill while designing this plane

>1. it must be strong enough to withstand speeds up to 100mph on a plane with a wingsweep of between 8-12 feet

I don't know a lot of this particular equation but I would guess that increased size + increased speed = control surfaces need to be more rigid and strong. although I think the servo motors would be suited for the ailerons as they would only need to be raised/lowered momentarily or in short bursts for turns and corrections, while the landing flaps would need to be more "solid" in function as they would be in position for extended periods and also get the most pressure while taking off and landing

>2. it has to be made with readily available resources (ie; no titanium structural systems, no jp-4, no expensive rare high end stuff)

th only exception to this would be the avionics of it as I would like to somehow mount a camera so I can fly around mountains from a birds eye view but in real time as it would be far out of my sight (think airforce drone operators) also I want to program it so that it can be piloted with an old video game flight stick or a console remote

>>1007118

begone britcuck

north America is best America

>>1007005 (OP)

Does it have canards?

>>1007143

it may have that, wing fences, or both, at the moment that is undetermined, but seeing as how it will be among faster model planes then it may require it to keep it from eating dirt at high velocity

>>1007153

>no hydraulics

Hydraulics are lighter, stronger, and more simple than any other mechanical system.

>>1007118

>something planes the air

>don't call it an airplane

I guess seaplanes aren't a thing.

>>1007244

well the theory behind it is that it would be simple to build in a workshop and maintain, hydraulics and other high pressure things would present new challenges and dangers.it is supposed to be something which can be made with cheap, and readily available materials while also limiting the required tooling to do so.

If you have any information on how to build hydraulics feel free to share

>>1007005 (OP)

Kek. Do you know anything about aircraft? Why would I want this in my cessna, for example? Airplanes don't use "hydraulic presses"anyway. Why would you make a bunch of rods and gears to move the flap, then put a motor there anyway? You know if you already have a motor that can turn a flap you don't need to attach rods to it right?

not this shit again

>>1007005 (OP)

Rods are too heavy you nigger

use wires and pulleys

>>1007146

>seeing as how it will be among faster model planes then it may require it to keep it from eating dirt at high velocity

You don't need to put your CoG so far forward the plane can't even take off unless you're a Lockheeb designer of course..

>>1007373

???

>>1007386

I've never had much luck with wires and cables desu, shit is always either too tight or too loose

>>1007438

>You don't need to put your CoG so far forward the plane can't even take off

my plan was to have the wings sit where the CoG is

>unless you're a Lockheeb designer of course

нет

>>1007247

Because they plane the sea as opposed to the air? The fuck are you on?

>it is supposed to be something which can be made with cheap, and readily available materials while also limiting the required tooling to do so

<he's never machined a gear

>new challenges and dangers

<he's never dealt with high-force springs

Hydraulics are miles safer than geared, mechanical systems, and incredibly easy to manufacture.

Pnuematic and other gas mechanics are much more difficult to produce and share the same dangers as gears, yet have been produced since primitive times. See: fire piston

Imagine being able to exert tons of force using suitcase sized equipment with minimal risk in the event of failure.

That's what you can do with hydraulics.

Bumble bees or any other flying insect? Hydraulics.

>>1007570

>having or being a hull designed to lift partially from the water's surface at high speeds

Yes.

Learn English, pajeet. Better yet, go back to India you Ganjes soup cannibal.

I guess the only question I have now is how can I make a piston/hydraulic mechanism and be able to control it remotely? I mean something small, like something that could fit in a 1ftx5ft RC wing, so nothing of great proportion

>>1007021

>freeware

I chuckled

can someone give me a quick run down of all the mathematical formulas needed when designing an airplane?

like lift+thrust/lbs or just any formulas which HAVE to go into it?

>>1007603

>I guess the only question I have now is how can I make a piston/hydraulic mechanism and be able to control it remotely? I mean something small, like something that could fit in a 1ftx5ft RC wing, so nothing of great proportion

The major issues are valves and cylinders at that scale, and at that scale, it's probably best to just build your own.

The pump could be driven off the main prop motor, or an auxillary pump that's idle, which could save battery power.

>>1007925

I've heard that there is a setup where the engine can be hooked up to a small generator of some kind which can power the avionics and charge the batteries as its being operated, but that could probably turn bad without some kind of regulator or auto off switch

>>1007595

>to skim across the surface of the water

Wow, hats off to you sir, you've turned a retarded retort into a logical argument. While I can't agree an aircraft planes air or water, I can't prove you wrong. If I were American I'd stand and clap then tip you a dollar.

>>1007974

to be honest I was unaware that it was a thing, I thought that the two kinds of actuators used were of the hydraulic/piston variety and the cable and pully variety.

also

> first nigger to think

>nigger

>thinking

>>1009080

what kind of engine should I put in an RC?

>turboprop

>radial

>regular piston engine

>steam engine

>jet engine

>turbine engine

theyre all slightly different but I want one that produces the most power in comparison with fuel consumption, I can work around the size if need be.

I would like to go with the turbo prop but it seems rather complex (more so than a jet, which it essentially is but with a propeller) and also there seem to be very little information on building one, or nearly any engine for that matter.

>>1009085

Don't most gas-powered RC planes use Glowplug engines? Why not just use that?

>>1009095

I was not aware of that prior, thank you.

my idea was to try to build an engine of some variety but in all honesty that would be very unlikely as I don't posses the skills needed to do so. just seemed like a neat idea to me to build a super powerful RC plane that could go far, fast, and high

>>1007024

Tbf I've learnt things in one night before

>>1009096

If you want to break 300 mph then use turbojet. Otherwise go electric.

>>1009085

>steam engine

>jet engine

>turbine engine

what the fuck man do some research before coming here asking stupid stupid shit

>>1009123

my goal was to break 100mph but i've never had a model plane before so its hard for me to picture/perceive it.

>>1009320

>steam engine

its like you never played pic related

>>1009325

I thought they were called turbo props but I guess its the same thing

also do you happen to be a fingerbox enthusiast?

>>1009367

>>1009085

i've been making r/c planes and drones for a while now, and i have my pilots license. You can break 100mph for under 150$ with a plane made out of cardboard, with a fairly standard electric engine and lipo battery.

But you're never gonna get there because you're already too fucking retarded to use google. No way you could understand the mechanics behind flight.

>>1009123

>>1009370

also one thing I wanted to do was somehow mount a live feed camera onto the front of the plane (fixed or swivel would be sufficient)

The things I think would be troublesome is 1. finding a suitable camera that doesn't have >480p quality (ie one that isn't granier than the beach) and 2. setting up the actual live feed, like somehow linking it to a computer or tv so I could pilot it in real time without actually having to be within sight of it, being able to control it with a console remote would be a plus but not required

>>1009375

well actually I've been staying up late scouring the wiki and other sources trying to find out the formulas and shit and in all honesty I've gotten some good info so far, but it's a lot of shit to know

(pls no bully)

>>1009377

Aircraft powerplants are an entirely separate area of research. They are equally as complex as the rest of the airframe combined. There's a reason the engine is the only part of the plane that must be seperately flight-certified before certifying the plane in the FAA.

this dude on youtube is somewhere to look if you're interested in airplane/powerplant design from a pilot's perspective, specifically ww2 warbirds. He seems to specialize in superchargers. https://youtu.be/mzQuq2FHdeE

just... do some more research. Look at some actual r/c turbine engine manufacturers... they aren't cheap. A 300mph r/c plane costs almost as much as a new car, if not more.

Start with standard electric, refine your airframe, learn the basics of r/c, then move to a ducted electric fan to simulate a jet engine, focus on perfecting your airframe, then take the jump and dump the cash into a jet once you feel confident enough. Here's a beginner engine that I've seen on NASA r/c testbeds on youtube: https://www.pbs.cz/en/our-business/aerospace/aircraftgines/jetgine-pbs-tj23u (you seriously underestimate the costs involved with a jet, trust me stick with electric/gas, even rockets are cheaper for r/c cus you can make fuel)
