Nakajima C6N Saiun “Myrt” manuals
A historical reference collection on the Nakajima C6N Saiun carrier-based reconnaissance aircraft, known by the Allied reporting name “Myrt”. This digital collection brings together two unique manuals in Japanese and English, supported by a supplied technical-intelligence reconstruction covering aerodynamic design, propulsion, handling, conversions and post-war evaluation.
Collection contents
- C6N1 User Manual, 「彩雲」艦上偵察機 C6N1 仮取扱説明書, Japanese
- C6N Photographic Collection, English
Technical reference
The supplied report describes a tightly packaged, low-drag fuselage around the 18-cylinder Nakajima Homare radial engine, a high-wing-loading laminar-flow wing, and interconnected high-lift devices combining Fowler flaps, split flaps and automatic leading-edge slats. It also discusses the carrier-elevator constraints that influenced the tail layout and the three-person crew arrangement.
The report identifies the production powerplant as the Nakajima NK9H Homare 21, with a supplied takeoff rating of 1,990 hp and a three-bladed constant-speed propeller. It presents reference figures of 610 km/h maximum speed at 6,100 m, 390 km/h cruising speed at 4,000 m, 5,300 km operational range with a 730-litre auxiliary tank, 10,470 m service ceiling, 2,968 kg empty structural weight and 5,260 kg maximum takeoff weight.
Further sections discuss reported high-altitude oil-pressure and power losses, the C6N2 turbocharger testbed, carrier approach handling, load sequencing, and the C6N1-S land-based night-fighter conversion. The report also summarizes post-war United States Technical Air Intelligence Center flight evaluations and presents a claimed 663 km/h test speed after the captured engine was serviced with high-grade American fuel and lubricants.
