A set of specific velocities is derived and it is shown to be the convex closure of specific engine velocities.
      
Control of Combustion Processes in an Internal Combustion Engine by Low-Temperature Plasma
      
The torsion angle specifies the current state of the shaft and can be used for the advanced disengagement of the engine in the event of the breakup of the transmission.
      
It is shown that the suggested adaptive system of estimating the torsion angle of the shaft ensures a high dynamic accuracy in the stationary and nonstationary modes of operation of the engine.
      
The mass of detached tanks is considered proportionate to the mass of consumed fuel; the mass of engine and auxiliary constructions, to thrust-to-weight ratio.
      
Locally Optimal Laws of Control of a Spacecraft Motion with an Electrodynamic Engine at Circumterrestrial Orbits
      
The locally optimal laws of control by this rod orientation are found, when one of the elements of the orbit gains the maximum increment under the action of this engine.
      
Numerical estimates of the gained increments are obtained, and it is demonstrated that this engine is a promising tool for the execution of light spacecraft maneuvers at low circumterrestrial orbits.
      
It is demonstrated that the optimum maneuver assures the maximum absolute value of the reentry angle and the insensitivity of the trajectory of descent with respect to small errors of orientation of the braking engine in the plane of the orbit.
      
Solving Optimization Problems for the Flight Trajectories of a Spacecraft with a High-Thrust Jet Engine in Pulse Formulation for
      
Classification of Gas-Dust Structures in the Upper Atmosphere Associated with the Exhausts of Rocket-Engine Combustion Products
      
The variants of injection into heliocentric orbits work from a low around-Earth orbit with one turn-on of the engine in this orbit and one turn-on at the end of the injection trajectory.
      
The problems for which injection to similar orbits is executed, using the low-thrust engine and with a combined regime of injection, are also considered.
      
The spacecraft flight is controlled by a thrust vector of a jet engine with restricted thrust (JERT).
      
The technique suggested is applied to the problems of optimal control over motion of the center of mass of a spacecraft controlled by the thrust vector of jet engine with limited thrust in an arbitrary gravitational field in a vacuum.
      
During the transfer the spacecraft is controlled by the vector of thrust of a limited-thrust jet engine.
      
Air-Breathing Liquid-Fueled Pulse Detonation Engine Demonstrator
      
Influence of a lift-engine air intake on the aerodynamic characteristics of a wing
      
This paper is devoted to the problem of the optimal shaping of the supersonic part of a pipe in those cases when the engine is designed to operate in two essentially distinct regimes.
      
Similarity laws are obtained for the transonic flow around axisymmetric bodies with a passage of the nacelle type air-breathing engine (or its root section) in the presence of a jet issuing from a nozzle.
