In summary, the conversation is about a senior design project involving the creation of a 747-400 wing model in PTC Parametric Creo 2.0. The challenge is obtaining crucial information from Boeing, such as the taper ratio, to accurately represent the real wing. Suggestions are given to use photographs and scale to estimate the chord at the root and tip and assume a linear variation in between. Another suggestion is to scale down from a given aircraft or use 2D drawings to create the model.

Hello,

This is in reference to a senior design project I must do. I have to create a 747-400 wing model in PTC Parametric Creo 2.0. The problem is that other than the wingspan, wing area, and sweep angle, Boeing does not reveal other crucial information such as taper ratio in order to find the root chord and the tip chord. I understand these things are company secrets. However, I need suggestions as to how to find the chords at the root and at the tip if the taper ratio is not given. The model must closely resemble the real wing. This wing model will then be ran into a CFD simulation program to find the aerodynamic properties. Any suggestions/ideas would be much appreciated.

Thank You

If all else fails, look for some good photographs and scale to get chord at the root and tip and then assume a linear variation in between.

yeah.like he said
scale down from given aircraft . 2D drawings...idid it many times in cllge year. Using Catia and it came out great.
 

1. How do you create a 747-400 wing model?

Creating a 747-400 wing model involves first obtaining accurate measurements and specifications of the actual wing. This can be done through blueprints or digital scans. Then, a scaled-down replica of the wing can be built using materials such as foam, wood, or plastic.

2. What are the challenges in replicating a 747-400 wing model?

One of the main challenges in replicating a 747-400 wing model is achieving accuracy in the dimensions and proportions. Another challenge is finding suitable materials that can withstand the weight and stress of the model's size and shape. Additionally, replicating the intricate details and features of the wing can be a time-consuming and delicate process.

3. What methods can be used to create a 747-400 wing model?

Some common methods used to create a 747-400 wing model include traditional handcrafting techniques, 3D printing, and computer-aided design (CAD) software. Each method has its own advantages and limitations, and the choice often depends on the resources and expertise available.

4. How accurate is a replicated 747-400 wing model compared to the real wing?

The accuracy of a replicated 747-400 wing model can vary depending on the methods and materials used. However, with careful attention to detail and precise measurements, it is possible to achieve a high level of accuracy in the replica. The use of advanced technologies such as 3D printing and CAD can also improve the accuracy of the model.

5. What are some potential uses for a replicated 747-400 wing model?

A replicated 747-400 wing model can have various uses, such as for educational or research purposes, as a display or exhibit in museums or aviation centers, or for aerodynamic testing in wind tunnels. It can also serve as a valuable tool for engineers and aircraft designers to study and understand the structure and design of the wing.
