Yes of course, www.airwar.ru know both!hesham said:does anyone know the MAI-56 and MAI-68 ?.
This type is described in the Krilya Rodiny magazine issue 1966 (05) as part of a two page article.The plane "RIIGA-1. One of the first student works Riga Institute of Civil Aviation was an easy flight " RIIGA-1 (Fig. 320), which he built in 1961-1964.
Very nice find, thanks. Now that it's properly identified, there is a handful of posts in that topic that really deserve splitting into a topic of its own.hesham said:the aircraft which we spoke about it before called MAI-405;
Very true, this! Can't believe it slipped my attention. However, when you read the text, it talks about a technical proposal for an "experimental aircraft for long-haul non-stop flight without refueling" designed at Moscow Aviation Institute. Powered by D-11 diesel aviation engines, [it would be] capable of circumnavigating the globe at the equator in less than 12 days." So my opinion is that "MAL-405" was probably a typo for MAI-405, a designation which fits nicely in the institute's numbering system.Cy-27 said:The caption on the experimental pusher 405 design, above, reads MAL-405 (МАЛ 405) - are we sure this is a Moscow Aviation Institute design?
Plane MG Lyakhov (Fig. 326). Sculptor by training, MG Lyakhov built in 1961 for the first nine months of his plane, which he called "Vintolet".
Aircraft wing having a disc shape in plan, intended to make the fan by folding type. Moreover, some sectors have been nested. Furthermore, in terms of disk wing was to provide lower landing speed and stability of the flight at high angles of attack.
In the central part of the disk was formed an annular channel, which rotate two coaxial propellers. Screws using a chain drive is driven by a two-cycle engines M-72 air-cooled.
Wing wooden construction with fabric covering. Cloth impregnated with a composition that MG Lyakhov developed independently. The composition consisted of aviation oil, linseed oil, solvent and stearin.
Ailerons were central rotary wing sectors, empennage cruciate scheme.
Flight aircraft weight 300 kg, length of 6 m. The width of the folded wing disc 2 m. With folded wings "Vintolet" could move along the highway, the car, tricycle landing gear with the front wheel. Motorcycle wheels and brake.
