Sukhoi 27 Flanker 3 Plan view Reverse Engineering

CATIA V5 R19. 2 days work on Reverse Engineering, design on wireframe and surface construction specialization.

I ve downloaded su 27 k diagram below. as usual, we need 3 view of the diagram that is side, front and top or bottom view.

Then, those three view picture is cut out using picture editor such as microsoft photo manager. This software is the best to do simple cut to the picture.

Then, 3 surfaces are created that is on the centre of the axis (0,0,0). Remind that you need to have the length, height and wing span of the aircraft so that you will have the correct size of the aircraft.


Then, using photo studio workbench, use add sticker, (icon with sticking paper), below CATIA screen, and select picture that you need as above. Please be remind that this picture can only be viewed with SHOW MATERIAL shading, below CATIA window.


Above is the side view of the airplane. In this method, ive use 3D curve to sketch the nose, wind screen @ cockpit, fuselage through the engine. Then, ive created points along the 3d curve.

3D spline are used to create the cross section of the fuselage from nose to the engine. Loft method have been used to loft the fuselage from nose until the engine. Before that, take note that i only made the surface of the left side of the airplane. my idea is, to apply symmetry to the create the surface.

This is the front view of the airplane. You can see that the airplane have been made symmetrical and you can see the continuation of the tangency on the connections.

As you can see, the tail have it different angle on the tip of the horizontal tail. Ive made angled plane, and airfoil sketch is created before the loft method is used to create the tail.


Below is the pictures of the finished airplane without any stickers on the airplane. Below is only the surfaces that ive changed the standard yellow colour of the airplane.


Here i show you, the wireframe of the airplane once we selected the wireframe shading. As you can see, the wireframe is used by CATIA to create the surfaces that we developed.


Below is finished su 27k. I am very very satisfied what i ve done in this project. Ive put sticker (same as above method) to the airplane. I also locate Russian Star logo on the wing and the vertical tail. Ive also put stickers on the engine.

Here ive finished my project doing a reverse engineering on Su 27k. This is an interesting project that i ve ever finished before on wireframe and surface design PLUS reverse engineering method.

check my b747 tutorial here and Dassault Rafale from france here. Using the same method as done in this post. happy learning !
