The Soloviev D-20P was a low-bypass turbofan engine rated at 52.9 kN (11,900 lbf) thrust. It was built by the Soloviev Design Bureau. The engine was used on the Tupolev Tu-124. A later derivative with increased bypass ratio, the D-20P-125, was developed into the Soloviev D-30 family of low and medium bypass engines.
