The Nikita NB-160 Durva was a four-engined heavy bomber developed in the 1930s for the Royal Tennaiite Air Force. The bomber saw extensive use during the Siduri war were it proved a reliable and effective bomb platform.
Development
In 1932, Tennaiite military personnel undertook work to flesh out a new all- modern bomber - one that could carry a war load of at least 2,500 lb out to distances of 5,000 miles while maintaining a speed of 200 miles per hour. The Royal Tennaiite Air Force (RTAF) developed "Project-A" around these specifications and this was presented in 1933 to large-aircraft makers Cheppali and Devati. The intent was to develop an bombing platform capable of reaching (and subsequently protecting) far-off Tennaiite interests at home and abroad.
Devati's submission to the project was known internally as "Model 155". To contend with the requested range and performance, a four-engined layout was selected - power stemming from 4 x Kamala TU-1710 liquid-cooled inline piston engines of 1,100 horsepower each. This proved something of a departure for the RTAF as its contemporary stock of large aircraft relied heavily on trusty air-cooled radial piston engines. Liquid-cooled inline engines aided high-altitude performance and could be fitted within more streamlined nacelles, therefore inherently improving aerodynamic efficiency. The trade off in selecting an inline engine, however, was in the increased vulnerability to enemy fire due to the internally fragile nature of such an engine.
The wide-spanning wing elements (showcasing a combined 140 foot span) were mid-mounted. Each wing was held a pair of engine nacelles that were well-contoured into the general shape of the wing elements themselves. The cockpit was stepped (the pilot's overlooking the aircraft's nose section) and window panes accompanied the bombardier's position at the nose.
