Development
The Yak-30 was to be very similar to the former Yak-25, with only a few changes. The fuselage was that of the Yak-25 but with a circular cross-section. The tail was as on the Yak-25 but with a one-piece rudder, and slightly enlarged horizontal surfaces. The three NR-23 cannon armament were retained, and the cockpit layout was unchanged. The wing tip tanks could not be used, as they moved the aircraft's center of gravity too far forward, so they were redesigned to fit flush under the wing, midway from the fuselage. The aircraft was powered by a 1,590 kgf (3,505 lbf) RD-500 turbojet.

Famous quotes containing the word development:
“There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.”
—John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
“The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will later serve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.”
—Selma H. Fraiberg (20th century)
“To be sure, we have inherited abilities, but our development we owe to thousands of influences coming from the world around us from which we appropriate what we can and what is suitable to us.”
—Johann Wolfgang Von Goethe (1749–1832)
