Design and Development
In the spring of 1946 OKB-115 set about designing the Yak-19. The aircraft was to have mid set, all-metal, straight wings and levered-suspension tricycle undercarriage, which would become the datum for future Fighter development in the USSR.
The design of the Yak-19 was a radical departure from the "step" layout of the earlier Yak-15 and Yak-17.
All tail surfaces were of metal construction, though only the elevators had tabs.
The tricycle landing gear were pneumatically operated, and had three nitrogen/oleo struts. The nosewheel was castoring, and retracted forward behind the engine ducts, faired by two doors. Fuel capacity was 815 liters (179.3 gallons) in two fuselage tanks, plus an additional 11 liters stored in the starter engine to assist ignition of the afterburner, which was fueled by a separate electrically driven pump.
The cockpit had a bullet-proof windscreen. A RSIU-6 radio was standard. Armament consisted of two Nudelman-Suranov NS-23 cannons, with 70-75 rounds each.

Famous quotes containing the words design and/or development:
“We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.”
—Joseph Addison (1672–1719)
“Such condition of suspended judgment indeed, in its more genial development and under felicitous culture, is but the expectation, the receptivity, of the faithful scholar, determined not to foreclose what is still a question—the “philosophic temper,” in short, for which a survival of query will be still the salt of truth, even in the most absolutely ascertained knowledge.”
—Walter Pater (1839–1894)
