Designed by Sergei Ilyushin’s bureau, the aircraft combined proven structural engineering with early jet-age aerodynamics influenced by German wartime research — and was powered by a Soviet adaptation of the British Rolls-Royce Nene turbojet.\u003c\/p\u003e\u003ch4\u003eAirframe \u0026amp; Aerodynamics\u003c\/h4\u003e\u003cp\u003eThe Il-28 features straight, unswept high-aspect wings with a custom aerofoil developed under the Soviet Central Aerohydrodynamic Institute (TsAGI). The airframe is built in five detachable sub-sections — nose, centre fuselage, rear tail, and two outer wing panels — a modular design that simplified field maintenance and forward deployment. Maximum structural speed is 850 km\/h IAS, with an official Mach limit of 0.82 M; exceeding this triggers strong buffet and aerodynamic asymmetry due to shockwave formation. Load factors are rated from −4G to +8G.\u003c\/p\u003e\u003ch4\u003ePropulsion — Klimov VK-1\u003c\/h4\u003e\u003cp\u003eTwo Klimov VK-1 centrifugal-flow turbojets, each delivering 26.5 kN (5,952 lbf) of dry static thrust at 12,000 RPM. The VK-1 features a single-stage centrifugal compressor linked to 8 interconnected combustion chambers, with spark plugs placed exclusively in chambers 3 and 8. Exhaust gas temperatures range from 500°C to 700°C under normal operations. Specific fuel consumption: 1.07 kg\/kgf·h. Field inspection interval: every 60 hours; overhaul life: 150–300 hours.\u003c\/p\u003e\u003ch4\u003eHandling \u0026amp; Stability\u003c\/h4\u003e\u003cp\u003eEarly flight tests conducted by test pilot Vladimir Kokkinaki confirmed the Il-28 as stable and highly agile for a bomber of its class. Controls are conventional push-rod mechanical, without hydraulic boost — giving the pilot direct, heavy aerodynamic feedback at high speeds. Flight logs note a slight roll tendency at high Mach numbers requiring proactive trimming. Landing gear is pneumatically actuated and must not be extended above 400 km\/h.\u003c\/p\u003e\u003ch4\u003ePerformance Data\u003c\/h4\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eMetric\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Speed\u003c\/td\u003e\n\u003ctd\u003e902 km\/h at 4,500 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCruising Speed\u003c\/td\u003e\n\u003ctd\u003e876 km\/h at optimum altitude\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eService Ceiling\u003c\/td\u003e\n\u003ctd\u003e12,300 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Range\u003c\/td\u003e\n\u003ctd\u003e2,400 km at 10,000 m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Takeoff Weight\u003c\/td\u003e\n\u003ctd\u003e21,200 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandard Payload\u003c\/td\u003e\n\u003ctd\u003eUp to 3,000 kg internal bombs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch4\u003eEngineering Systems\u003c\/h4\u003e\u003cp\u003eFire suppression relies on an automated carbon dioxide loop running through the engine nacelles, supported by an inert gas tank-pressurisation system.
