(Los Pakis no quieren el motor chino, confían en el ruso)<h3>IS THE NEW KLIMOV RD-93MA ENGINE AN OPTION FOR THE JF-17?</h3>On 08 July 2020, United Engine Corporation (UEC) announced that one of its companies, Klimov, started testing its newly developed turbofan engine, the RD-93MA.[1] The RD-93MA is an improved variant of the RD-93, which powers the JF-17 Thunder, the mainstay multi-role fighter of the Pakistan Air Force (PAF).Klimov will carry out tests on the RD-93MA at the P.I. Baranova (TsIAM) facility. Klimov will assess the RD-93MA’s behavior under simulated flight conditions. Later, it will proceed towards flight design tests.According to UEC, the RD-93MA offers a range of improvements over the RD-93. These include “increased thermodynamic parameters” as well as improved fan design and automatic powerplant control system. It also improved the RD-93MA’s safety features – such as the addition of an emergency engine start mode – a necessity because the engine is meant for single-engine aircraft.UEC was reportedly developing the RD-93MA since at least 2012, if not earlier.[2] In fact, UEC stated that it had gotten a request to develop the RD-93MA from a “foreign customer.” The RD-93MA was intended to offer a thrust of 9,300 kgf, a noticeable improvement over the RD-93’s 8,600 kgf.[3]In addition, one could assume that the RD-93MA will also contain improvements from the RD-33MK (i.e., the improved variant of the RD-33), such as a full authority digital engine control (FADEC) system, longer time-between-overhaul (TBO), and a longer engine lifespan.Though not explicit, it generally seems that the intended target customer of the RD-93MA is Pakistan, i.e., the largest user of the RD-93 (via the JF-17). However, it is unclear when those engine can factor into the JF-17 and, in light of the current geo-political environment, if the PAF will seek it.<h2>Will Pakistan Seek the RD-93MA for the JF-17 Block-III?</h2>The JF-17 Block-III is a significant upgrade over the Block-I and Block-II, and while an engine change would have made sense in some respects, it is unlikely the PAF will pursue a new powerplant at this stage.According to PAF officials, the first two Block-IIIs are already under production, and the 50 aircraft are all due by 2024.[4] The PAF would not have started the Block-III’s production without securing a functional and certified turbofan engine. By UEC’s own admission, the RD-93MA is in its initial testing stage (and not yet ready for flight tests). Thus, the RD-93MA is not ready for integration and testing, much less deployment.<a href="https://quwa.org/2020/07/12/is-the-new-klimov-rd-93ma-engine-an-option-for-the-jf-17-2/">Is the New Klimov RD-93MA Engine an Option for the JF-17?
