    Dihedral
AI Thread Summary
The discussion focuses on the advantages of different wing dihedral configurations regarding lift generation and stability. A straight wing without dihedral is noted to provide more lift but sacrifices roll stability. Among the dihedral options, a configuration that features a partial span dihedral starting from the fuselage is suggested to yield better lift than a straight wing. Additionally, a full span dihedral is considered the simplest to construct, requiring fewer joints compared to partial span configurations. The conversation highlights the importance of balancing lift and stability in wing design.

hi.
i have a doubt.
Which configuration is more advantageous to the wings in terms of lift generated and stability?
1. a wing with a full span dihedral from fuselage to the tip

2. A wing with a partial span range dihedral from tips to somewhere in the wings and then straight till fuselage

3. a wing with a partial span dihedral from fuselage to some point on wing and then straight wings till the tip.

please help if anyone knows.

It is my understanding that a straight wing with no dihedral will provide more lift than any dihedral configuration but at the cost of roll stability. As to which dihedral is better it may be a good idea to remember there are losses in lift within the proximity of the fuselage of an aircraft. A dihedral from the fuselage to some point along the span and then a straight span would provide more lift than a straight wing from the fuselage to the same point along the wing span followed by the same dihedral.

which dihedral is simple in construction?
 
The simplest dihedral in construction is a full span dihedral. You make one righ and one left wing and join them in the middle wit bridge or sandwhich plates. If you have the dihedral start or stop at some point along the span you have twice the joints to make.
If you are making a model it is easy to go without a dihedral and use a low center of gravity to cause stability - like a pendulum.
 
thanks for your advice. i will surely consider it
 

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/

Thread 'SpaceX Starship development: 7th flight January 10'

Watch the progress live This is a fully stacked Starship (top) and Super Heavy (bottom). A couple of too-small-to-see cars near the bottom for scale, I also added a Saturn V and the Statue of Liberty for comparison. 120 meters tall, about 5000 tonnes when fully fueled. Twice the mass and over twice the thrust of Saturn V. The largest rocket ever built by mass, thrust, height, and payload capacity. N1 had the largest diameter.[/size] But its size is not the revolutionary part. It is designed...

Thread 'Radiation Hard Electronic Design for LVO Long Mission'

Venus does not have a magnetosphere, so the Galactic Cosmic Rays (GCRs) environment shall be much worse than in a LEO environment. Looking to the std radiation models for Venus, the standard radiation-hard space level electronic component with tested immunity LET = 85 MeV-cm2/mg seems not enough, so, for example, a 1cm2 Si die will suffer considerable flux above this level during a long mission (10 years for example). So, the question is, usually we are not paying attention to latch-up...
