DailyDirt: Weird Airplane Designs
from the urls-we-dig-up dept
Airplane designs have evolved quite a bit over the years. Some new planes might as well be alien spacecraft compared to the designs most people recognize. Outside of the super secret stealth aircraft, though, there are some interesting planes that are more fuel efficient and have strikingly different silhouettes. Here are just a few examples.- Honda has a luxury jet, Hondajet, going into commercial production. Hondajet's engines are mounted in an unconventional way -- sitting on pedestals above each wing.

- More fuel efficient plane engines could incorporate open rotor designs. Open rotor engines can have pretty large diameters and not require heavy shielding... and they look cool. [url]
- This fuel efficient concept combines a fuselage that provides some lift along with rear-mounted engines. Placing two engines right next to each other in the rear might be a problem if one of them fails and takes out the only other engine on this plane. [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Re: Fuel Efficiency
Apparently these have now been solved - but at present it is held up by the need for the airframe manufacturers to agree with the engine manufacturers about the configuration. Since there are three engine manufacturers (PW,GE and RR) and two airframe manufacturers (Airbus Industrie and Boeing)it is likely that the engine manufacturers will go 2-1 and no-one wants to be the 1 or to be the aiframe manufacturer who backs the 1. So there is apparently an impasse.

Re: Fuel Efficiency
It sounds like this would be a replacement for turbofan planes running shorter routes at lower speeds. What I want to know is why is the open design so much more efficient? The article didn't explain it.

The Honda design has been tried before

Made them as a kid. They flew really well.

Re:
The MIT plane looks like it shares some characteristics with that plane, though not the semi-delta wing configuration.
