Hey all, i'm doing an essay on the difference in trajectory of plastic and feather shuttlecocks when affected by a change in optimal angle and initial velocity. I'm only looking at 2 forces - gravity and air resistance. I'm really stuck at trying to calculate the drag coefficient of the shuttles as i dnt even have the formula. I have researched and found it a differential equation but i'm still confused as to how it came about. Any help would be greatly appreciated
Drag coefficient can only be obtained through experiments or simulations. I would assume that it's hard to simulate due to the fact that the shape of the shuttle changes depending on speed. The best way is to make an educational assumption. Are you writing an essay for highschool?
Drag Coeffcient Thanks for the reply..yes i'm in highschool and am writing a 4000 word essay on it. i've found the formula for it on this website but i'm not sure of its credibility. Can u suggest any sources for it? Moreover, i planning on assuming that the shuttles fly parabolically to find the initial velocity. Thus, using Newtons 3 laws of motion. bUt I'm not sure if i shud do this as it didnt always fly parabolically. Do u have any suggestion for this?
thanks But can you give me more details as to how u got that and i have to slightly explain it too. i will reference you in my essay, can i please have your full name
Essay on the difference in trajectory of plastic and feather shuttlecocks . shiksha12 ... It's great that you are doing an essay on the difference in trajectory of plastic and feather shuttlecocks. What I find is... when the shuttlecock is being hit as in a Smash , the softer skirt of a plastic shuttlecock would be folded in more than the rigidness of the feather shafts. Therefore, the drag coefficient from a plastic shuttlecock when smashed would be much lower than from a feather shuttlecock. However, for shots of Clear and Dropshot, the skirt of the plastic shuttlecock gets more time to open up again. Therefore, for these 2 shots, the average drag coefficient could be quite similar (from start to finish). So you will need to calculate the drag coefficient of each shot trajectory, at the point when the shuttlecock is being hit and at the point when it arrives at the other side to the net (when it reaches the opponents' rackets). Don't forget to let us know the results on completion of your study/essay of this topic. .
shiksha12, you might want to read this thesis (click on the link in this post.) It should be a very useful read for what you seek. And, you could credit Dr Alison Cooke in your essay. All the best --------------- PS: Doesn't 'shiksha' mean education?
I was thinking of doing all the different types of shots available . However due to many constraints i only did 2 types of serve - flick and low serve. I know that Smash would have been an excellent type of a shot but i cannot analyse it properly. For air resistance i am planning on using linear drag but i am still confused about the drag coefficient for plastic and synthetic shuttlecocks. I dnt know how to calcluate it. All i know is that 2 factors are important : air density ( pressure, temperature, viscosity) and surface area of the object. Can someone please help me put the pieces together so that i can calculate the drag coefficient. Thanks, Shiksha (which does mean education)
New Composite Shuttle design Hello, We are a small company in the United States. We have developed a new composite shuttlecock. Would you be interested in testing it and sharing some feedback on its performance? Brad
Testing New Shuttlecock We do not feel that a confidentiality agreement is necessary. We would prefer not to post an image at this time. Our development is in final stages. We are looking for feedback so that we can refine the durability and flight characteristics of the shuttle. Thanks, Brad
New Shuttlecock Design Testing We appreciate your interest. We were hoping to get feedback from players in the United States. We did not want to incur the expense of shipping overseas for product testing. Brad
I just replied the PM. Yeah, I am interested. Personally, I prefer to do local pickup (NY metro area), if possible.
