aircraft. Lyulka also designed the upper stage engines for the Soviet moon rocket N1. In the 1970s, Pavel Sukhoy asked Arkhip Lyul'ka to design a new engine with unorthodox characteristics for installation on the projected Su-27. The challenge was taken up, and although Pavel Sukhoy died in 1974, his work was carried on by his successors and colleagues, including Lyulka. The primary difficulty in designing this aircraft appeared to be in the engines, which had to be constantly redesigned and upgraded. As a result of the intensive work of Arkhip Lyul'ka and his team, the work on the new engine, AL-31F, was finally accomplished in the early 1980s. Arkhip Mikhailovich Lyul'ka died on 2 June 1984. Achievements Overall, the achievements of Arkhip Lyulka have become decisive for Soviet Union and its allies. To this day, the patent for double jet turbofan engines widely used in all sectors of the world's aviation belongs to him. The AL-31 alone has become the cornerstone for various international developments in both civilian and military sectors, now undertaken by NPO Saturn, the heir to Lyulka's OKB.
