Eidis, Arkadiy lonovich
Russian engineer. Chelomei's First Deputy General Designer 1965-1985, leading development and production of the Almaz space station and TKS manned spacecraft. Earlier headed development of cruise missiles at NII-642 from 1952 and at Chelomei from 1958.

Born: 1913-10-03. Died: 2004-10-13.

Eidis was born in the city of Mogilev-Podolsky Ukraine. Following the death of his father, he moved with his mother and two sisters to Moscow in 1922. After completing secondary school, he worked as a mechanic at a factory. After studies at the Moscow Institute of Electrical Engineering, he transferred to the Central Institute of Aviation in 1934. In parallel he worked at SP Gorbunov's Plant 22 (now MV Khrunichev). There Eidis acquired broad experience as a manager, production worker, technologist, and designer. He graduated as a Mechanical Engineer in 1937. He was promoted through the ranks at Plant 22, becoming Deputy Chief of the Pilot Production Plant in 1942. This manufactured aircraft designs by VM Petlyakov and VM Myasishchev. 

In 1952 Eidis was appointed Deputy Chief Designer of the Mikhail Orlov's NII-642 Research Institute. Here his talent as a designer and technical manager emerged in his work on cruise missile deign. His team created the Shchuka series of anti-ship cruise missiles. These used liquid propellant engines and were intended for carriage under the wing of the Il-28 bomber or launch by naval vessels, such as the Project 57 destroyer.

In 1957, NII-642 became a branch of VN Chelomei's OKB-52. In 1958 Eidis was appointed Deputy Chief Designer of this branch. From 1963-1965 he led OKB-52's branch inherited from the Lavochkin bureau, which was engaged in development of the P-25 and P-35 cruise missiles.  Eidis always demanded full consideration of alternate approaches before making a design decision. For example, in determining how best to seal the pressure hull of the Almaz space station, he conducted a thorough review of existing experience at other design bureaus and foreign firms. The choice of rubber sealing elements for the space station Almaz and its reentry capsule only occurred after reviewing relevant work for submarines, aircraft cabins, and Russian and American spacecraft. After this Eidis took his own, original decision. A similar process was used in selection of the materials for ICBM warhead reentry vehicles for the UR-100 family.

Eidis possessed an extraordinary work ethic. He worked every day to 12 to 14 hours, every Saturday, and sometimes Sunday.

In 1985, Eidis retired. He had been awarded the Order of Lenin in 1963, the Lenin Prize in 1967, and numerous other awards and recognition. To the end of his life he kept a clear mind and his inherent sense of humor.
