Because power to weight ratios are more important when building something useful, and right now the margins are pretty tight. There are plenty of toys that look like flying saucers, but if you’re trying to carry a camera and enough batteries to be useful you design for utility.
Are you talking about the RC Quadcopters that hobbyists use for photography and racing? Or the UAV military craft?
I’ve seen the former only once in the wild, when a Real Estate photographer was taking pics of a house, and I also know a friend of mine has one but I’ve not seen it yet.
What would you consider a pretty drone? And what do you expect to do with this drone? Right now they’re utilitarian tools, and frankly I think most look pretty cool as they are tuned to deliver the maximum utility and form following function is appealing in itself. Would you rather have an ineffective but pretty shell on your drone or one that can carry a larger payload?
I have been wanting to tell people about this for a while. Thank you for the excuse.
The most distinctive thing about drones may be their hindquarters. Have you noticed how many of them have the vertical stabilizers set in a V, and upside down? There is a reason for this. The propeller is in the rear. The stabilizers are set that way to prevent the prop from hitting the ground on take-off.
(The nose goes up, the tail goes down and the prop tends to hit the ground.)
I noticed a year or two ago the South Koreans displayed an evil North Korean drone. It had the distinctive back end, but the propeller was in the front. The just built it to look like one of the big boys.
I call it “The Bluenose Principle”. The Bluenose was a Nova Scotia schooner that,when it slid off the drydock, was called the most beautiful ship ever built. When it got out into the waves, guess what? It turned out to be the fastest ship ever built, too. What a coincidence!
The eye, over millennia, has learned to recognize things that work best, and learned to call that “beauty”. An arrow, a spinning top, a kite, a running cheetah – all beautiful, and called that simply because our eye detects that they function with the least form resistance.
I’ve heard something similar about airplanes. I originally heard it said about the 1930s, when the highest performing planes were streamlined like Art Deco sculptures. The implication was that aeronautical engineering back then was more of an art than a science. Doing a search, Wikipedia credits “if it looks good, it will fly good” to Bill Lear (of Lear Jet fame), but it doesn’t say when he said it. Oddly, I think the 1930s designs still look right, but science has taken over and new planes don’t look like that anymore.
Interesting that you cite the Bluenose for this. I’ve been on the Bluenose II in Nova Scotia.
There’s a similar concept in writing software: If the code looks good, it will be easier to modify and fix bugs in. It won’t necessarily be the most machine-efficient code (truly tight code tends to look dense and busy, which isn’t conducive to reading) but it will be good code in the ways that actually count.
Of course, you have to know what good code looks like before you can tell the pretty from the ugly, and each language has its own take on this concept.
