Joined-wing and box-wing aircraft

[Stargazer]

I'm nowhere near fluent in Russian, but the text seems to indicate a patent from the SibNIA company.

 

[hesham]

I think that Russian's article is from NASA reports.

Hi,


here is the Prandtl Electrical VTOL Unmanned Aircraft;

Great Hesham
it is the modern version Prandtplane
from Italy

Thank you Qxev.

Here is another box-wing design. I don't know anything about it except it's called the Stalker and might involve the Mikoyan bureau.

S-232 project...
6-8 local administrative planes with the jointed wing and forward horizontal plumage. The plane developed in common with experts of TsAGI within three years, but because of a lack of means of work were frozen at a stage of end of the outline sketch.

Very cool my dears Ucon and Stargazer.

Another "Stalker" design, this time the Stalker-502, emanates from the TsAGI's NIO-3 bureau.

Since it's from TsAGI, it is probably only notional and does not announce an upcoming product...


[This is from a Stalker-501 presentation — a tilt-rotor design will be covered in a separate topic.]

many thanks for useful information

Sorry for not linking these earlier. So many Le Bourget photos to process and properly document!

 

[qxev]

enormously! ! ! !


thank you very much!!


what it for firm?

 

[dan_inbox]

Am I the only one to think that the plane on the photos posted by Stéphane will have an airflow problem?


I am not aerodynamics expert, but it looks like during rotation the air intake will be in the wake of the front wing, which is not the best of times to experience degradation of power...


Thanks for the photos. Wish I was there too.

A 2006 AFIT thesis paper that you may find interesting: http://www.dtic.mil/dtic/tr/fulltext/u2/a453708.pdf

Abstract

The Air Force Research Laboratory’s Munitions Directorate has been looking to
extend the range of its small smart bomb. Corneille [6] has conducted tests to determine
the aerodynamic characteristics of joined wings on a missile and determine if joined
wings are more beneficial than a single wing configuration. The concept of retrofitting
wings on the bomb introduced an interesting problem: storage before deployment. This
study conducted steady-state low speed wind tunnel testing of a joined wing
configuration that morphed from a compact configuration for storage to a full extension.
These steady-state tests examine differing sweep angles of the same joined wing
configuration. The lift and drag as well as pitching moments and rolling moments were
determined and analyzed for the effects of morphing.

From Kryl'ya Rodine 11/1992,


here is a box-wing aircraft,Beka.

 

[Stargazer]

"Beka" is not the name of the airplane. For a start it reads "Veka". It means "century". The title means the "biplane of the 21st century".

Thank you my dear Skyblazer.

I remember seeing a joined wing version of the S-3 that was supposedly going to be a replacement for the E-2 Hawkeye... In searching Boeing E-X on Google I have found nothing, does anyone have any more information on it?

Attached is a picture from the book it is in.

Hi,

here is the White Diamond box-wing aircraft;

http://www.gibbsguides.com/Article26_White_Diamond_Part2.htm

 

[Stargazer]

here is a group of joined-wing and box-wing aircraft;
4- NASA agricultural aircraft

Aircraft #4 is the Rutan Model 58 Predator (or maybe 59, never knew which was which), developed for ATAC and later replaced with the more conventional Model 120, or Predator 480.
