This generator provides the production of high concentration nitrogen and, accordingly, the separation of high concentration oxygen. However, the oxygen produced is not used in the production cycle.
Известен также генератор кислорода/инертного газа с двумя газоразделительными блоками (Раtепt Application Publication Ns US 2003/0233936 A1 от 25 декабря 2003 года), в каждом из которых установлено два типа мембранных газоразделителей: в одном - полупроницаемые половолоконные мембраны типа HFM для генерирования в качестве основного продукта азота (OBIGGS), кислород как побочный продукт не используется на летательном аппарате и сбрасывается в атмосферу; в другом (блоке) - молекулярные сита с применением процесса адсорбции-РSА - для разделения воздуха на азот и кислород.

В настоящем изобретении предлагается расширение возможностей использования продуктов, получаемых в газовых генераторах, в частности кислорода. Это достигается применением смеси, полученной в газоразделительном генераторе и обогащенной кислородом, в двигателе летательного аппарата, в частности, в камере сгорания двигателя. ТакоеThe present invention proposes the expansion of the possibilities of using products obtained in gas generators, in particular oxygen. This is achieved by using a mixture obtained in a gas separation generator and enriched with oxygen in an aircraft engine, in particular in a combustion chamber of an engine. Such
ЗАМЕНЯЮЩИЙ ЛИСТ (ПРАВИЛО 26) применение обогащенного кислородом воздуха в двигателе летательного аппарата позволяет существенно повысить его качественные показатели, газодинамические и экологические, приводящие к уменьшению расхода топлива, снижению массы двигателя, повышению ресурса камеры сгорания, значительному снижению выбросов вредных примесей на выхлопе двигателя в атмосферу, уменьшению вероятности прожога стенки камеры сгорания, снижению нароста сажи и нагарообразования и т. п.SUBSTITUTE SHEET (RULE 26) the use of oxygen-enriched air in the aircraft engine can significantly improve its quality indicators, gas-dynamic and environmental, leading to lower fuel consumption, lower engine mass, increased combustion chamber life, a significant reduction in the emission of harmful impurities from the engine exhaust into the atmosphere, and a decrease in the likelihood of burning through the chamber wall combustion, reducing the growth of soot and carbon deposits, etc.
Для решения этой задачи обогащенный кислородом воздух, отделенный в генераторе, подводится к камерам сгорания маршевых двигателей через средство распыления, например, через эжектор, чем обеспечивается большая равномерность распределения температуры в камере.To solve this problem, oxygen-enriched air separated in the generator is supplied to the combustion chambers of the main engines through a spraying device, for example, through an ejector, which ensures a more uniform temperature distribution in the chamber.
В настоящем изобретении также предусматривается смешение обогащенного кислородом воздуха в смесителе, установленном в выходной магистрали генератора подачи воздуха, обогащенного кислородом, с воздухом, подаваемым из магистрали кондиционирования, для обеспечения противопожарной безопасности двигателя и летательного аппарата в целом.The present invention also provides for the mixing of oxygen-enriched air in a mixer mounted in the output line of an oxygen-enriched air supply generator with air supplied from an air conditioning line to ensure fire safety of the engine and the aircraft as a whole.
В системе предусмотрена контрольно-регулировочная аппаратура, позволяющая контролировать процесс распределения воздуха на разных режимах полета.The system provides control and adjustment equipment that allows you to control the process of air distribution in different flight modes.
Система функционально может быть связана с элементами ВСУ и/или техотсеков для подачи в них в случае необходимости воздуха, обогащенного кислородом или азотом.The system can functionally be connected with the elements of the APU and / or technical compartments for supplying, if necessary, air enriched with oxygen or nitrogen.
Настоящее изобретение будет более понятно с учетом нижеследующего описания предпочтительных примеров осуществления со ссылками на сопроводительные чертежи, где на фиг. представлена схема заявляемой системы.The present invention will be better understood in view of the following description of preferred embodiments with reference to the accompanying drawings, in which FIG. presents a diagram of the inventive system.
Предлагаемая в настоящем изобретении система газоразделения и газораспределения самолета включает в себя генераторы 1 разделения воздуха на азот/ кислород, основными элементами которых являются rазоразделительные мембраны. Мембраны могут быть известного из предшествующего уровня техники типа: полупроницаемые полуволоконныеProposed in the present invention, the gas separation and gas distribution system of an aircraft includes air / nitrogen / oxygen separation generators 1, the main elements of which are separation membranes. Membranes may be of the prior art type: semi-permeable half-fiber
ЗАМЕНЯЮЩИЙ ЛИСТ (ПРАВИЛО 26) мембраны или молекулярные сита. Генераторы 1 входной магистралью 2 соединены с линией системы кондиционирования 3, в которую подается воздух из соответствующей ступени компрессора маршевого двигателя 4. Для каждой отдельной заявляемой системы (для каждого маршевого двигателя и ВСУ) может использоваться генератор 1 с необходимым количеством мембран, в данном случае указано 3 мембраны, для получения необходимого количества газа. Однако, в каждом конкретном случае количество систем, а также количество мембран в генераторе может изменяться в зависимости от расчетных условий. Входная магистраль 2 соединена с системой кондиционирования 3 в такой точке, где обеспечиваются приблизительно следующие параметры воздуха: давление P ~ 2,5 ати (245,15 КПа); t = 50°-60°C. После прохождения генераторов линии объединяются и образуют единую выходную магистраль 5 подачи воздуха, обогащенного азотом, и единую выходную магистраль 6 подачи воздуха, обогащенного кислородом. Надо понимать, что после генераторов 1 воздух имеет очень высокую концентрацию кислорода и азота, порядка 96%, и термин "обогащенный" следует понимать, исходя из приблизительно такой концентрации. Магистраль 5 обычно обеспечивает подачу обогащенного азотом воздуха в надтопливное пространство топливных баков по линии 7. Кроме того, в настоящем изобретении для обеспечения пожарной безопасности такой воздух может подаваться в техотсек 8 или в отсек ВСУ 9 по линии 10. Магистраль 6 воздуха, обогащенного кислородом, в настоящем изобретении связана с камерами сгорания 11 маршевого двигателя 4. На входе в камеры сгорания 11 в магистрали 6 установлено средство распыления 12, например, эжектор. Подача воздуха, обогащенного кислородом, в камеры сгорания 11 повышает эффективность сгорания топлива, и, как следствие этого, улучшает экологические характеристики продуктов сгорания, уменьшает загрязненность стенок камер сгорания и др. Введение средства распыления 12 дополнительно улучшает указанные характеристики путем повышения эффективности смешивания всех газово-жидкостных компонентов в камере сгорания 11.SUBSTITUTE SHEET (RULE 26) membranes or molecular sieves. Generators 1 by input line 2 are connected to the line of the air conditioning system 3, into which air is supplied from the corresponding stage of the compressor of the marching engine 4. For each separate inventive system (for each marching engine and APU), generator 1 with the required number of membranes can be used, in this case 3 membranes, to obtain the required amount of gas. However, in each case, the number of systems, as well as the number of membranes in the generator, can vary depending on the design conditions. The input line 2 is connected to the air conditioning system 3 at a point where approximately the following air parameters are provided: pressure P ~ 2.5 ati (245.15 KPa); t = 50 ° -60 ° C. After passing the generators, the lines are combined and form a single output line 5 for supplying air enriched with nitrogen, and a single output line 6 for supplying air enriched with oxygen. It should be understood that after generators 1, the air has a very high concentration of oxygen and nitrogen, of the order of 96%, and the term "enriched" should be understood based on approximately this concentration. The line 5 usually provides nitrogen-enriched air to the fuel space of the fuel tanks via line 7. In addition, in the present invention, to ensure fire safety, such air can be supplied to the technical compartment 8 or to the APU compartment 9 via line 10. The oxygen-rich air line 6, in the present invention, it is connected with the combustion chambers 11 of the main engine 4. At the entrance to the combustion chambers 11, a spraying device 12, for example, an ejector, is installed in the highway 6. The supply of oxygen-enriched air to the combustion chambers 11 increases the efficiency of fuel combustion, and, as a result, improves the environmental characteristics of the combustion products, reduces the pollution of the walls of the combustion chambers, etc. The introduction of atomization means 12 further improves these characteristics by increasing the mixing efficiency of all gas liquid components in the combustion chamber 11.
ЗАМЕНЯЮЩИЙ ЛИСТ (ПРАВИЛО 26) В системе, соответствующей настоящему изобретению, может быть установлен смеситель 13. Этот смеситель может обеспечивать дополнительный поток воздуха по перепускной линии 14 из системы кондиционирования 3 в магистраль 6 подачи обогащенного кислородом воздуха. Такой перепуск воздуха на разных режимах регулирует концентрацию кислорода в магистрали 6, чтобы избежать взрывопожарную ситуацию на входе в камеры сгорания 11.SUBSTITUTE SHEET (RULE 26) A mixer 13 may be installed in the system of the present invention. This mixer may provide additional air flow through a bypass line 14 from the air conditioning system 3 to the oxygen-enriched air supply line 6. Such air bypass in different modes regulates the oxygen concentration in the line 6, in order to avoid an explosion-fire situation at the entrance to the combustion chamber 11.
На режимах взлета и набора самолетом высоты, т. е. до наступления крейсерского режима, когда возможности маршевого двигателя 4 не позволяют в полной мере обеспечить генераторы 1 достаточным количеством воздуха, входная магистраль 2 системы соединена (через систему кондиционирования) линией 15 с ВСУ 9 для обеспечения подачи необходимого количества воздуха в генераторы 1. С камерами сгорания ВСУ 9 может быть связана магистраль 6 по линии 16, также через средство распыления.In take-off and climb-by-plane modes, i.e., before cruising, when the capabilities of the marching engine 4 do not fully provide the generators 1 with enough air, the input line 2 of the system is connected (via the air conditioning system) with line 15 to the APU 9 for ensuring the supply of the required amount of air to the generators 1. With the combustion chambers of the APU 9 may be connected to the highway 6 through line 16, also through the spraying means.
Кроме того, система снабжена различной контрольно-регулировочной аппаратурой, например, управляемыми кранами 17 и 18, датчиком 19 контроля давления и концентрации кислорода, обратными клапанами 20 и 21. Через управляемый кран 17 на некоторых режимах, например, в аварийной ситуации, магистраль 6 подачи обогащенного кислородом воздуха связывается с элементами подачи кислорода в кабину экипажа и в пассажирскую кабину.In addition, the system is equipped with various control and regulation equipment, for example, controlled valves 17 and 18, a pressure and oxygen concentration sensor 19, non-return valves 20 and 21. Through a controlled valve 17 in some modes, for example, in an emergency, the supply line 6 oxygen-enriched air is associated with oxygen supply elements in the crew cabin and in the passenger cabin.
Следует понимать, что представленные в данном описании предпочтительные примеры выполнения настоящей системы никак не ограничивают заявляемое изобретение, и можно представить дополнительные модификации системы, объем которой ограничивается только представленной далее формулой изобретения.It should be understood that the preferred examples of the present system presented in this description do not limit the claimed invention, and it is possible to imagine additional modifications to the system, the scope of which is limited only by the following claims.
