9.3 FOREIGN CAPABILITY
At the 1989 Paris Air Show, a Russian-made K-36D seat gained wide public attention when the pilot successfully ejected from a MiG-29 after engine failure at an altitude of
300 ft with the aircraft in an 80 degree pitch-down attitude (Figure 9.7). The airspeed at ejection was approximately 100 knots. Although the parachute deployment occurred when the pilot was only 10 to 20 ft above ground, he survived with little more than bruises on his back, abdomen, and a small cut on his right eyelid.
The K-36D ejection seat is standard equipment in the Former Soviet Union high-performance combat aircraft, and is rated for survivable ejections at speeds of 0-755 KEAS (0-1400 km/hr) and altitudes of zero to 80,000 ft. This is in contrast to US ejection seats which are designed for ejection speeds of 0-600 KEAS (0-1110 km/hr) and altitudes of zero to 50,000 ft.
Тесты в США проходило кресло К-36Д-3,5Э, к результатам испытаний приведенная Вами ссылка и относится, а это глава 9,5.
значить, действительно с английским у тебя проблемы.

И еще - когда тесты проходили в США, К-36Д- 3,5 еще не было.

In 1989 at the Paris Air Show, a K-36D ejection seat gained wide public attention when the pilot successfully ejected from a MiG.29 after an extremely low altitude engine failure. The K-36D is standard equipment in Russian high-performance aircraft, being rated for survivable ejections at speeds of 0-755 KEAS. In 1993, a Foreign Comparative Testing (FCT) Program was initiated to evaluate the Soviet designed K-36D ejection seat. The objectives of this program were to increase USAFIUSN knowledge of the state of Russian ejection seat technology, confirm or refute Russian claims on the performance of the K-36D ejection seat and associated personnel equipment, determine the relevance of Soviet ejection seat technology and fight crew equipment to development of a technology base for expansion of the performance envelope of USAF!USN escape systems and to develop working relationships between the US and Russian technical teams. The program consisted of eight ejections from modified MiG-25 aircraft at altitudes up to 56,000 ft at Mach 2.5, and three rocket sled tests at speeds up to 755 KEAS.
