NM-1, P.V.Tsibin

17k NM-1 after landing from RSR/NM-1 page at 'True supersonics!'

Technology demonstrator for the RSR project. Such a testbed was a necessity, because novelties of the RSR caused reasonable (and unreasonable) concerns among aviation specialists and authorities.

NM-1 was built at Dubna aviation factory, and was used for evaluations at speeds up to Mach 0.98. Internal structure and equipment were substantially simplified, but airdynamically NM-1 was identical to the RSR. Landing gear was borrowed from the LL program. It included a jetissonable cart used for takeoff (see photo below) and single landing ski with wooden boot (photo above).

(11k) NM-1 prior to takeoff, from NM-1 page at 'True supersonics!'

First flight was performed on April 7, 1959 by test-pilot of LII MAP Akhmet-Khan Soultan. Since low-speed performance was the main concern (similar in layout F-104 had serious landing problems), the emphasis was made on low speed handling at different flight regimes. During series of 32 flights all estimated characteristics were confirmed. Even more, during minimal speed trials NM-1 outperformed escorting Yak-25. Series fighter simply stalled while NM-1 slowed down...
