Back TsAGI A-12

TsAGI A-12

OOK 6th Brigade under Skrzhinskii designed A-10 six-seat transport autogyro with M-22 in 1934 but dropped this in favour of high-speed wingless machine with fully controllable rotor. Design in parallel with small A-14 which flew first and assisted perfection of A-12 wingless autogyro. Direct-control rotor derived from A-7, with similar engine drive before takeoff. Roll control by rotor only, tail with central rudder (extension of fuselage) and two Scheibe fins on strut-braced tailplane with elevators. Shavrov loosely describes fuselage and engine as I-16 (fighter); in fact steel tube with fabric, and engine cowl with gills. Two-position Hamilton prop, single-seat cockpit, very strong main gears with oleo struts and wide-track spatted wheels with toe brakes. Cautious taxiing and hops 10 May 1936 by A.P.Charnyavskii, eventually 17h 55min in 43 flights until rotor blade came off 23 May 1937 killing I.Kozyrev. Cause never found but ascribed fatique; almost halted autogyro work.

Just wanted to thank Mr. Jerry for everything you have done for us. In less than 15days of working with you, our credit score was raised high enough to be able to qualify for a mortgage loan that we were not able to before. Besides that, everyone there was so professional and friendly and easy to work with that it made the whole experience quite enjoyable. I have already recommended you to several people and will continue to recommend your services to everybody I come in contact with. I contacted JERRYLINK CREDIT GROUP via their customer service: JERRYLINKGROUP@GMAIL.COM

We will fix your credit; remove all negative items, clear loans, collections and hard inquiries and also raise your score to 760+ ASAP. These were the exact words from M. Jerry when I contacted him via JERRYLINKGROUP at GMAIL dot COM / 6265140620. I decided to give JERRYLINK CREDIT GROUP a try and to my greatest surprise it worked out for me. In less than 11days after all documentation; my score drastically increased to 810 across the three national credit bureaus (Equifax, Experian and TransUnion), I could no longer sight evidence of collections, negative marks, mortgage loan, collections and hard inquiries on my credit report. I honestly appreciate Mr. Jerry for fixing my credit.
