Design and Development
Following testing of the Yak-15U, Yakolev ordered a major redesign, incorporating a nosewheel, while putting aside commonality with the Yak-3. In addition, the main gear had to be redesigned to place the wheels behind the aircraft's center of gravity. The main gear were moved behind the front spar, and when retracted they filled most of the space between the spars. This caused a major redesign of the fuel tanks and reduced their capacity to just 680 liters (150 gallons). This necessitated the addition of two 200 liter (44 gallon) jettisonable tanks, which hung under the tip of each wing. The addition of the tip tanks required a redesign of the structure of the wing so that the aircraft could still maintain a load bearing of 12g. The vertical stabilizer was enlarged and a periscope was also added above the windscreen on most series aircraft. Armament, systems, and equipment were virtually unchanged.

Famous quotes containing the words design and/or development:
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“They [women] can use their abilities to support each other, even as they develop more effective and appropriate ways of dealing with power.... Women do not need to diminish other women ... [they] need the power to advance their own development, but they do not “need” the power to limit the development of others.”
—Jean Baker Miller (20th century)
