Aircraft Easy Drawing
Aircraft Easy Drawing - In aircraft design there are some critical measures that will determine if your plane will fly. Those measures are the Static Margin (SM), Center of Gravity (CG), Horizontal Stabilizer Volume (VH), Vertical Stabilizer Volume (VV), and Cubic Wing Loading (CWL).
When power is concerned the additional measures of Power-to-Weight Ratio (P/W) and Thrust-to-Weight Ratio (T/W) are very important. In order to find these key measures we must first find a few other measures before hand. These measures would be the dimensions and areas of the main wing, horizontal and vertical stabilizers, the aerodynamic centers (AC), Neutral Point (NP), and the distance between the two centers.

Don't worry about the AC and NP yet, I'll show you how to find them! When finding the area and dimensions, the critical ones are the labeled dimensions A (Root Chord), B (Semi-Span), & C (Tip Chord) in the picture below;
Hi all do note that the "D" value obtained here is inaccurate. I have tried to use 2 online calculator and another formula that uses tail volume and the difference is <8% error. Here : http://chrusion.com/BJ7

content/uploads/2019/02/Plane-5-1.jpg" > Airplanes come in many shapes and sizes, but there is one easy way to categorize them – by how they are propelled forward. Those three categories include jet engine, propeller and rocket engine. Most airplanes are flown by a pilot, but some are designed to be remotely or computer-controlled with drones.
To start out analyzing your design you'll need a 3 view drawing of your plane on a piece of paper. I suggest a scale drawing on a piece of graph paper. Keep it simple, and keep it boxy.
Boxy is easier to build! Here is a great example below.

setup, try it yourself.

Is this guys still on? I can't understand about .02 or .05 is it 0.05 or 0.02? BTW i calculate with VV formula and it's ended up with 0,1 ... Am i doing something wrong ?
Reply 5 years ago I hope you gain some great information from this article. It summarizes my understanding of aircraft design and hopefully helps others as well. Now, the next step is for you to build your creation!
I would suggest a boxy foam and tape method much like timcarlielle and tak145 did here in instructables. Feel free to comment, PM, or email me with further questions or requests. Also, thanks to my friends over at Dual Design R/C for confirming my thoughts and helping me in writing this article.
FlyBoy38L Add rectangles to the bottom two tail sections. Fill the rectangles in with lines. Draw a rectangle with a corner missing on the top tail section, and add a smaller rectangle inside it. Sketch line details on the wings, engines, and cockpit.
Finish with a couple rectangles for hatches on the body side and some details on the front bubble window. The very first plane, was of course invented by the Wright brothers back in 1903. Since then, aircraft technology continued to develop through the development of the first jetliner in 1952. This tutorial is a nod to that classic looking aircraft that was in service.
for over 50 years.

You will need to watch the units you use! No crazy engineering needed here. I'll be using an example of a conventional airplane with the main wing in front of the stabilizers (Stab). I'll also be using simple tapered wings to keep complexity low.
Awesome! We have NP, ACs, and CG found. What is next? the Tail Volumes! What are they? They are a measure of the effectiveness of the stabilizers. We'll start with the horizontal stabilizer. Using the Areas, Lengths, and MAC use the equation at the top of the first picture below to find the Horizontal Stabilizer Volume (VH).
Typical values for this are between .35 and .8. .35 is less effective and .8 is SUPER effective.

Here, we'll show you an illustration of each step and then give you a description of how to draw it. Question 4 years ago on Step 1

Now we can find the location of the Center of Gravity (CG).
This is found by determining the Static Margin. The Static Margin is a measure of stability of your plane. Typically the SM is a distance based on the length of the GMC or MAC. Most planes have a SM of 5% to 15% of the MAC which means the CG is 5% MAC to 15% MAC in front of the NP.
A plane with a Static Margin of 5% is limited in stability and 15% is great stability. Never put the CG behind the NP!!!!! Just don't do it! You've been warned. Now we can move onto finding the Vertical Stabilizer Volume (VV).
Below is a photo of how to find VV. Using the areas and distances once again, use the equation listed above and find VV. Typical values for VV are between .02 and .05. Once again .02 is a less effective tail and .05 is a SUPER effective tail.
Next Stop, Neutral Point! (NP) With the AC of all your wing panels found, we can find the NP of your airplane. The NP is like the AC of your entire airplane. With your drawing ready, measure L (The distance between the AC of the Main Wing and Horizontal Stab.) and use that in addition to the areas of both to find the length D. The equation is listed in the middle of the three in the
picture below. We can now use D to find the location of NP by subtracting it from L.
