The first Soviet fighter to utilise wing sweepback, and
consequently known unofficially as the Strelka (Dart),
the La-160 featured 35° of leading-edge sweep on a
wing of 9.5% thickness. When initially flown on
24 June 1947, the La-160 was fitted with an RD-10 turbojet
rated at 900kg, with which it could not
get airborne fully laden. After initial handling trials, the
La-160 was fitted with an RD-10F which provided an
afterburning thrust of 1170kg and with
which, after diving and then levelling off, a speed of
1060km/h was allegedly attained at
5700m, this being equivalent to Mach=0.92.
The La-160 carried an armament of two 37mm NS-37
cannon, but was utilised primarily as a research vehicle
in the development of more advanced fighters.

| Peter Hamel, p.hamel(@)t-online.de, 26.11.2006 During a recent historical review about the "Birth of Sweepback" I was referring to the interesting La-160 including fotos. But I could not find an in-flight foto. Is there somebody who has ever seen an in-flight foto of the La- 160? A response would be highly welcomed. Dr. Peter Hamel |
