Inventor: BEKNEV V S
IPC: F02K3/04
Filed: 2000-05-24
Granted: 2002-03-10
Abstract: FIELD: aeronautical engineering. SUBSTANCE: proposed method is realized by means of mixed power plant consisting of two gas-turbine engines interconnected by means of heat-exchange apparatus; method includes stepped compression and expansion of working medium in each engine accompanied by cooling at compression and heating at expansion; one engine works in closed cycle and other engine works in open cycle. Transfer of heat from first gas-turbine engine is effected on hot side at atmospheric pressure. Reception of heat in second gas-turbine engine is effected on cold side at increased pressure, in closed cycle. When engine works as turboprop, exhaust of hot gases is effected after heat exchange with closed cycle. When engine works as turbo-jet engine, exhaust of part of gas is effected before heat exchange with closed cycle. EFFECT: enhanced economical efficiency. 6 dwg

Abstract: FIELD: communication systems. SUBSTANCE: slave base station attains synchronization with master base station through messages transferred from mobile station and received by mobile station either in soft service transmission area between master base station and slave base station or within coverage area enabling mobile station to support communications with slave base station. When mobile station does not communicate with both master and slave base stations, master base station measures signal passage delay time in forward and backward directions between mobile station and master base station. Master base station conveys pseudonoise code used by mobile station over backward link to slave base station. Slave base station locks on signal from mobile station and finds out when signal has arrived from mobile station. Then slave base station executes this operation and evaluates delay time between signal transmission from mobile station to slave base station. These measurement and evaluation data are used by slave base station to determine error in system time of slave base station. EFFECT: ability of time synchronization when part of network can receive centralized sync signal and use it for synchronization and part of base stations cannot receive it. 8 cl, 9 dwg

Across one section of air flow forced removal of thermal energy is conducted and heat exchange between 2n heat exchange sections of air flow grouped in heat-exchange pairs of sections located on opposite sides from section of forced removal of thermal energy is organized. Heat exchange is implemented by heat transfer from i-th heat exchange section to 2n+1-i-th section, water condensate is removed from that part of air flow where temperature falls to temperature of dew point. In this case forced removal of thermal energy is conducted across at least one more section of mentioned air flow and all sections of forced removal of thermal energy are arranged between n-th and n+1-th heat exchange sections. Facility to recover water from air has conduit for transportation of air flow which houses fan, heat-removing element, collector of water condensate communicating with part of conduit and multisectional heat exchanger. Each section of heat exchanger is made of two heat exchange elements and total number of heat exchange elements is equal to 2n. Heat exchange elements included in one section are positioned on opposite sides from heat removing element, sections themselves are heat insulated one from another. Heat exchange elements are coupled in pairs along heat flow so that according to order of arrangement i-th heat exchange element is coupled to 2n+1-i-th heat exchange element. Facility also has at least one more heat removing element. All heat-removing elements are mounted in series one after another and are located between n-th and n+1-th heat exchange elements. Fan is installed in conduit between last in direction of air flow heat-removing element and n+1-th heat exchange element. EFFECT: maintenance of effective condensation of water vapors. 29 cl, 7 dwg
