    По тази схема вече прилича на това http://en.wikipedia.org/wiki/Yakovlev_Yak-30_%281948%29 Но пък няма оребряване на крилете,каквото виждаме на снимката на Я-ка.

      Това,че напречното сечение на крилете в основата си е по-тънко отколкото в края и затова колесника се прибира навън(не по -посока на тялото) ? хмммм Е въпроса тука е "на кого му е притрябвало подобно решение и с каква цел ?"

        Не знам за вас ,но ми прави впечатление че колесника се сгъва на навън и досата дълеч от тялото!

          А при Як-а това го няма.

                Ахаа ето къде бил ключа за бараката

                performance at low speeds and high angle of attack. The stagnant airflow over the wing tended to "slide" towards the wingtips, which caused them to stall before the rest of the wing at high angles of attack. In this situation the center of lift would rapidly shift forward relative to the center of mass, pitching the nose up and leading to an even greater angle of attack or, in extreme cases, end-over-end tumbling of the aircraft. Planes caught in this regime would often stall and crash, and a rash of such accidents on the F-86 Sabre led to the term Sabre dance. The most famous incident was the loss of F-100C-20-NA Super Sabre 54-1907 during an attempted emergency landing at Edwards AFB, California on 10 January 1956 which was caught by film cameras set up for an unrelated test. The pilot fought to retain control as he rode the knife-edge of the flight envelope but fell off on one wing, hit the ground and exploded with fatal results.

                The Thunderceptor's most notable design feature was intended to address this problem. The wings were built to have considerably more chord (distance from front to back) at the tip than root, allowing them to generate more lift. This neatly addressed the problem of Sabre dance by delaying the point of stall on the tip to that of the entire wing. A side effect of this design was that the tips had more internal room, so the landing gear was mounted to retract outward with the wheels lying in the wingtips, using two small tires instead of one larger one. Another design change was the ability to vary the angle of incidence of the wing as a whole, tilting it up for low speed operations during takeoff and landing, and then "leveling it off" for high-speed flight and cruise. This allowed the fuselage to remain closer to level while landing, greatly improving visibility.

                    Имам усещането, че си прекалил с фотошопа Доста детайли не се връзват и май се опитваш да ни пратиш за зелен хайвер.

                            Аз не разбирам от реактивни самолети, но това не е ли "Мираж" Ф1? Или някаква вариация по тая тема.

                              много студено не е мираж нито е вариация на темата

                                Питах дали не е снимка на израелския изтребител Лави - потенциален, но заклан конкурент на F-16?
