Очень часто случается так, что наиболее известные вещи являются в прямом смысле только «верхушками айсберга». Такая ситуация сложилась и с одним из интереснейших проектов конструкторского бюро имени П.О. Сухого. Их экспериментальный самолет С-37 – он же Су-47, он же «Беркут» – лет пятнадцать назадtranslate.google.fr
"The "Dry(Sukhoi)" has already had experience in the design of light (up to 20 m) single-engine fighter with wings - Project C-22. "
I think that air intake shape is different between this plan view and this wind tunnel test model.
Yet again, low quality of post. The first link and picture is purely speculative and has numerous points of difference from the real project. The second reference is simply a Google translation of the actual source article from https://topwar.ru/165697-proekt-su-27km-obratnaja-strelovidnost-dlja-avianosca.html while the image posted is Paralay's speculative drawing of S-22, already posted in this topic.Hi! S-22.
"Since 1983, the Sukhoi Design Bureau has begun working on project S-22 the topic of which was the creation of 5th gen fighter plane. The aerodynamic layout of this machine."
"Within the framework of the S-22 project, we conducted the necessary studies and prepared a complete set of working documentation. It was proposed the construction of an aircraft scheme "duck" with front horizontal tail and CBS. The aircraft was equipped with one engine(???); there was a single cabin. Take-off weight reached 22-24 tons, including several tons of combat load.
At the final design stage, it turned out that the S-22 turned out to be excessively heavy. Correction of these shortcomings required a radical revision of the project. In this regard, work on S-22 was stopped, and the accumulated experience was put at the heart of a new project - S-32."
That’s a speculative drawing from Janes long ago. I wouldn’t pay much attention to it. Also it was already posted IN THIS TOPIC, 12 years ago, by hesham. There was no purpose to reposting it.
Hi! Su-27KM. I can see complicated shape engine air intake and exhaust nozzle in following pictures. Also I can see hook.
