Development
In response to a directive No.1561-868 from the Council of Ministers and Ministry of Aircraft Production order No.571, issued in August 1955, the Tupolev Design Bureau was to create an airliner that had a range of 8,000 km (4,971 mi), based on the Tupolev Tu-95 strategic bomber, powered by 4 powerful Kuznetsov NK-12 engines driving massive contra-rotating propellers.
The Tu-114 used the basic wing, empennage, landing gear, and powerplants of the Tu-95 bomber, mated to a totally new pressurized fuselage of much larger diameter. To cope with the increased weight, increased landing flap surface area was required, and the flap chord was increased compared to the bomber's flaps. The wing was mounted low on the fuselage, giving the Tu-114 a much higher stance on its landing gear than the bomber. As a result a new nose landing gear strut was required, although the main landing gear remained unchanged.
The Tu-114 was able to reach speeds typical of modern jetliners (880 km/h), carrying up to 224 passengers in maximum carriage configuration, although a more usual number for long-distance transcontinental flights was 170 passengers which enabled the planes to be fitted with such luxuries as sleeping berths and even a dining lounge for the upper class cabin.

Famous quotes containing the word development:
“... work is only part of a man’s life; play, family, church, individual and group contacts, educational opportunities, the intelligent exercise of citizenship, all play a part in a well-rounded life. Workers are men and women with potentialities for mental and spiritual development as well as for physical health. We are paying the price today of having too long sidestepped all that this means to the mental, moral, and spiritual health of our nation.”
—Mary Barnett Gilson (1877–?)
“Information about child development enhances parents’ capacity to respond appropriately to their children. Informed parents are better equipped to problem-solve, more confident of their decisions, and more likely to respond sensitively to their children’s developmental needs.”
—L. P. Wandersman (20th century)
“And then ... he flung open the door of my compartment, and ushered in “Ma young and lovely lady!” I muttered to myself with some bitterness. “And this is, of course, the opening scene of Vol. I. She is the Heroine. And I am one of those subordinate characters that only turn up when needed for the development of her destiny, and whose final appearance is outside the church, waiting to greet the Happy Pair!””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
