Analysis of low-thrust liquid rocket engines with a methane air pump unit
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016 The first airplane working on cryogenic fuel was developed in the USSR in early 1980s on the basis of the passenger aircraft Tu-154. It was then modified using a hydrogen engine installed instead of one of the three kerosene engines.

Simulation of the work process of a two-stage pump with a first-stage hydraulic drive
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016 This article describes a method of CFD-modeling of a two-stage high-pressure pump. The main feature of the pump is the hydraulic drive of the low-pressure stage that takes energy from a high-pressure flow.

Multi-Hamiltonian Structures on Beauville's Integrable System and Its Variant [PDF]
, 2006 We study Beauville's completely integrable system and its variant from a viewpoint of multi-Hamiltonian structures. We also relate our result to the previously known Poisson structures on the Mumford system and the even Mumford system.Comment: This is a ...

On the Darboux-Nijenhuis Variables for the Open Toda Lattice [PDF]
, 2006 We discuss two known constructions proposed by Moser and by Sklyanin of the Darboux-Nijenhuis coordinates for the open Toda lattice.Comment: This is a contribution to the Vadim Kuznetsov Memorial Issue on Integrable Systems and Related Topics ...
