DCS: MiG-17F Development Report

The MiG-17F was powered by the VK-1F turbojet engine, a classic Soviet design that was built on the proven VK-1 turbojet of the MiG-15bis. The engine originated as a reverse-engineered and improved version of the British Rolls-Royce Nene centrifugal-flow turbojet. In 1946–1947, the UK government (under Prime Minister Clement Attlee) authorized the export of Nene engines to the Soviet Union for diplomatic reasons. The Soviets initially produced a direct copy designated the RD-45, then refined it—addressing metallurgy and other issues with larger combustion chambers, an improved turbine, and other modifications—into the more powerful VK-1 under the leadership of designer Vladimir Yakovlevich Klimov. The VK-1 was a workhorse of its era, powering the dawn of Soviet jet aviation, and the VK-1F added an afterburner for that extra kick when needed. The afterburner itself is a simple affair: Fuel is sprayed into the exhaust and ignited, providing a significant increase in thrust. There was a short delay before full afterburner power was achieved, a hallmark of the robust, no-nonsense engineering of early jet engines.

The Look

In real life, through the lens of a camera, the MiG-17F’s afterburner puts on quite a show. Its wisps, segments, and bloom in the exhaust plume are notable. With the naked eye, what you’ll see is a steady, bright flame. This is what we’ve recreated for you in the DCS: MiG-17F module.

The Feel

There’s no afterburner light indication in the MiG-17F cockpit. Instead, pilots rely on aircraft feel and changes in acceleration to provide cues when the afterburner is lit. In DCS, you’ll pick up on these same cues through sound, aircraft response, and subtle shifts in engine readings without a dedicated indicator light.

Afterburner Operation

MiG-17F pilots didn’t just slam the throttle into afterburner whenever they felt like it. Soviet doctrine emphasized engine longevity, so standard takeoffs were usually done without afterburner; even training flights kept engine management conservative. The afterburner was reserved for moments when you really needed it, and it delivered about 25% more thrust. 

In DCS, you’ll need to keep a close eye on afterburner use. Once it’s lit, engine temperatures will start climbing, and when you see the needle nearing 730°C (into the red), it’s time to back off. Push it too far, and you risk engine damage or even failure. After shutting down the afterburner, bring the RPMs below 11,200 to help cool the engine. You’ll usually see Exhaust Gas Temperature (EGT) drop below 690°C within half a minute, and you’ll then be able to safely use the afterburner again.

The Bottomline

Even without the afterburner, the MiG-17F is no slouch. At combat weight, you can expect to hold a turn rate of 13 to 14 degrees per second. Kick in the afterburner, and that jumps to around 16 degrees per second, giving you a competitive edge in a dogfight. 

During the early Cold War years, 13 to 14 degrees per second, and up to 16 with afterburner, made the MiG-17 a capable opponent when compared to faster but less agile fighters of the era. Later fighters like the F-16A and F-5E Tiger II would eventually raise the bar, but in its day, the MiG-17 set the standard for turn rate.
