Serkan Sen Posted June 28, 2022 Author Share Posted June 28, 2022 The model had dummy nose tires to give an idea how the nose wheel strut looks like together with tires: Now the time has come to correct the tires and to add wheel rims. Here are the dummy tires: First the tire profile and groves have been improved with best guesstimate (I don't know the exact cross section): And some fine details were also added: Next step is to add text and some other fine details to the tire model.

Serkan Sen Posted June 28, 2022 Author Share Posted June 28, 2022 The nose tire modelling finally finished. I added few details including some text and the holes on the tire surface. I don't know what these holes in both the main and nose wheels are actually for but I assume they show how worn the tires are. I haven't added all the text because they will be too small to print. But I can add them later if I believe that they can be printable. Next step is to model the wheel rim. Serkan 3 Link to comment Share on other sites More sharing options...
David H Posted June 28, 2022 Share Posted June 28, 2022 James Goodall would probably know about the tyres. 1 1 Link to comment Share on other sites More sharing options...
Serkan Sen Posted June 29, 2022 Author Share Posted June 29, 2022 The basic wheel rim model was generated again with best guesstimate: Next step is to add some details. Serkan 2 Link to comment Share on other sites More sharing options...
Serkan Sen Posted June 29, 2022 Author Share Posted June 29, 2022 The bolts and nuts as well as the axle nut have been added: Serkan 2 Link to comment Share on other sites More sharing options...
Serkan Sen Posted June 29, 2022 Author Share Posted June 29, 2022 The label plates (?) have been added to the model; M-21 wheel: SR-71A wheel: Here are more pictures; And together with the nose gear strut: Next step is to model main wheels...

Serkan Sen Posted July 5, 2022 Author Share Posted July 5, 2022 I started modelling the mid main wheel. The tire surface details and texts will be added soon. The inner and outer wheels will be derived from the mid one. Serkan 3 Link to comment Share on other sites More sharing options...
Serkan Sen Posted July 6, 2022 Author Share Posted July 6, 2022 The inner wheel model has been completed: The outer wheel will be added soon to complete the MLG assembly. Serkan 7 Link to comment Share on other sites More sharing options...
Serkan Sen Posted July 8, 2022 Author Share Posted July 8, 2022 Outer wheel model has been completed: Next step is to model the bay doors. Serkan 4 Link to comment Share on other sites More sharing options...
Serkan Sen Posted July 24, 2022 Author Share Posted July 24, 2022 Before starting the bay doors modelling some tire details were added: There are still other surface details to be added. But most of the work has been completed. Serkan 6 Link to comment Share on other sites More sharing options...
Serkan Sen Posted July 26, 2022 Author Share Posted July 26, 2022 The tire profile has been corrected. Also missing labels such as the tire size and the tire surface details have been added: It was a wise decision bringing the laptop to our five weeks vacation. Today the temperature outside is over 45 degrees Celcius and I had to find something to do in the airconditioned home till 16:00 o'clock 😓🥵 Serkan 6 Link to comment Share on other sites More sharing options...
billn53 Posted July 28, 2022 Share Posted July 28, 2022 You made me realize it’s been a long time since my last vacation ☹️ But, 45C? 🔥🔥🔥 What oven are you vacationing in? 😱 2 Link to comment Share on other sites More sharing options...
Serkan Sen Posted July 29, 2022 Author Share Posted July 29, 2022 We are currently on the east coast of Aegean sea. Last week due to extreme heat waves and strong wind from inland to the coast there were many wildfires here in Turkiye (since couple of weeks the Turkey's official name has been changed by UN 😁). One of them was very close to us and fortunately with a quick response (which is very occasional) the fire has been extinguished within 3 hours: This was a good collaboration of CL-415, Mi-17 and CH-47. Since yesterday the temperature has been dropped to 35 degrees Celsius. Most probably somewhere in inland it is heavily raining...

Most probably melted ice caps drop the temperature in North Atlantic. But here we are very close to North Africa/Arabian desert zone. 🥵🥵🥵 2 Link to comment Share on other sites More sharing options...

After working a bit more on available pictures of operational aircrafts, the profile has been modified for the inflated tire: The above picture shows the comparison of inflated and flat tire models. Next step is to find a way to model loaded inflated tire. Serkan 5 Link to comment Share on other sites More sharing options...
Serkan Sen Posted August 3, 2022 Author Share Posted August 3, 2022 I have discovered a miracle tool namely "blender" to modify/distort an existing mesh model including STL files. Using lattice modifier mode I managed to generate the loaded tire model: From the above images right to left you can see the flat, inflated and loaded tire models. Next step is to repeat the process to generate the loaded tires for various rotation angles. Serkan 4 Link to comment Share on other sites More sharing options...
Serkan Sen Posted August 4, 2022 Author Share Posted August 4, 2022 Here are the loaded tire models for different rotation angles: Serkan 3 Link to comment Share on other sites More sharing options...
Brandy Posted August 4, 2022 Share Posted August 4, 2022 Please don't make the mistake of having the loaded tyres bulge out at the bottom! They don't, unless they're flat! I just add an offset plane and cut the bottom off for loaded tyres, then add a slight chamfer so it's rounded. Ian 1 1 Link to comment Share on other sites More sharing options...

Ian Thanks Ian, Then maybe the best solution is to model inflated unloaded tire and then slightly sand the bottom round the edges to simulate loaded case. 🤔 Serkan 1 Link to comment Share on other sites More sharing options...
Brandy Posted August 5, 2022 Share Posted August 5, 2022 I would model the inflated unloaded tyre, then cut a little off with an offset plane. You can add a slight fillet to round it off at the sides. More accurate and repeatable than sanding! Ian 1 Link to comment Share on other sites More sharing options...
