  1. ДЗ в Израиле, вакансия тандем-инструктора. Требования: - звание Т-И - подтвержденный опыт прыжков - медицинские документы - английский разговорный Предложение: - минимально гарантированная зарплата - 1000 долларов. - кросс-трейнинг на Strong. Желающим обращаться ко мне, sad_home@mail.ru
  2. <img src="http://www.skycentre.net/images/forum/news/certificatPIA.jpg"> Международная Ассоциация Парашютной Индустрии (PIA), после рассмотрения вступительных документов, вынесла позитивное решение и приняла в свои члены Риггерский Центр "SkyCentre", в лице Алексея Шарадкина aka Lexa. Поздравляем!
  3. За 10 мин. можно... Гусары, молчать! Среднее время укладки нормального укладчика- где-то около 5 мин, если купол отдают с зачекованными клевантами и слайдером - еще меньше. Да да.. Я на вас посмотрю
  4. В молодости я поработал укладчиком в Москве. И в насыщеный день около 100 укладок делал. Так что 20 - это как раз полежать и в небо поплевать Потусить и отдохнуть...
  5. Я тебе намекаю, очень призрачно, судя по всему - тонкая ирония не цепляется больше отбитым мозгом - что количество - это очень далеко не качество, и приводить в качестве оценки летных характеристик (а именно это спрашивалось изначально) распространенность - ну, по меньшей мере, новое слово в парашютостроении. Так лучше? Я могу сильно постараться, и возможно, у меня получится еще проще написать...
  6. Хммм. Сдается мне, что Радар делает по количеству их обоих, причем вместе взятых. Думаем еще, заканчиваем заниматься даунланчем..
  7. На "Майские буги" Майского. С 29 апреля по 10 мая. 2 спортсмена по 10+ прыжков в день - 20 укладок в день 10 грн за укладку, плюс проживание. Требования: здравый смысл, ответственный подход, умение быстро укладывать маленькие парашюты с предсказуемыми результатами. Кастинг провожу лично, могу потренировать... Желающим звонить - 8067 506 76 21, Леха P.S. Прекрасная возможность отдохнуть, потусить в клевом месте, а по ходу - еще и подзаработать денег
  8. Ну, если подойти к вопросу вообще принциапиально глубоко - то даже купола одного и того-же производителя отличаються, если взять разные года выпуска. Проблема все та-же - такого понятия, как "парашютная ткань тип, ост." не существует. Поэтому производители покупают ткань, тестируют ее по своим минимально-допустимым параметрам, и потом пускают в производство (или заворачивают). При этом, учитывая, что опции при заказе: "А пошейте мне плиз куполок из супер-пупер ткани" нет, мы вибираемо те, що маемо P.S. Икарус хорошо держит (точнее, держал) Европу, типа локальный производитель, все дела... В Америке он от ПД очень и принципиально далек

    Quest от Аtmogear

    Компания Atmosphere Gear презентовала свой новый продукт - skydive ранец Quest. Среди отличительных характеристик производителем называются: -удобство пользователя -большой выбор опций по цветам и конструктивным элементам Заявленная производителем стоимость - 700 Евро, правда, за эту цену пользователь получает: - подвесную систему с кольцами на бедрах - коллапсируемую медузу - мячик на медузе - выбор цвета Заказная форма предложенного производителем для тестирования образца была заполнена 12 апреля, так что ждем ранца с нетерпением, чтобы составить собственное мнение по этому поводу
  16. Я бы не рискнул проводить прямой аналогии Как никак GL - это подьем и разгон купола с 0 до балансировочной скорости, а скайдайв - торможение этого же купола с 200 км до балансировочной. Физ. процессы разные, как я понимаю
  17. Будучи на Чайке в субботу был крайне расстоен одним зрелищем. Парашютист, герой неба и оператор на всю голову, отдает на укладку свой парашют. Парашют берет укладчик, и начинает его "типа" укладывать. Мы сидим и наблюдаем за этим. Неаккуратно пробив ряды, укладчик пытается свернуть хвост. Получаеться не очень. С трудом скрутил, начинает выдавливать воздух. Расползается, слайдер выпал. Крутился крутился - так и не победил. Решаем помочь человеку - уложили купол в камеру. Укладчик продолжает зачековывать стропы в соты. Получается какое-то макраме. На наши возгласы "типа не правильно это, типа аккуратней" получаем от персонала исчерпывающий ответ - "а он только начал работать у нас, учится..." После того, как укладчик запихивая камеру в контейнер развернул ее вокруг своей оси, мы забрали систему от греха подальше и уехали... Я понимаю стремление к работе молодых укладчиков, но тренироваться, наверно, стоит все таки на кошечках, а не на парашютистах. Характерные причины лайндампа все помнят - про сьехавший слайдер и неупорядоченные стропы? Удар на раскрытии - это даже не отказ. это посуровее будет. А тем более для оператора Ну, в общем, вот такое вот фе. Тщательнее нужно, товарищи...
  18. Чем глубже зачекован купол (ну, до определенного значения ) - тем быстрее и резче наполнение, так как купол имеет максимальную площать по отношению у потоку, и соответственно максимальное торможение. Корректировать глубину зачековки для каждого конкретного купола - это такое, само по себе стремное занятие, так как результаты не всегда предсказуемы. Проще обратиться к тому, кто уже занимался такими доработками и знает точно - что и на сколько нужно отпускать\прибирать. Обратись к Косте Зябликову, например... По поводу несимметричного наполнения - на 90 процентов это либо перекос тела в подвески, либо слишком резкая работа на задних для коррекции - останавливая один разворот, мы закручиваем купол в другой... Я рекомендую, если ваш купол страдает такими шутками (мой например очень это любит) - в момент раскрытия взяться руками за группы СК (правую и левую) и просто развести их в стороны - купол будет наполняться значительно стабильней, и не будет привычки дергать все что не попадя
  19. И много у тебя формаций больше 50-ти человек? А меньше - так ты уберать должен, по идее, а не готовиться запутываться Отмазка про завязывание забита уже купольщиками
  20. А на второй круг при ошибочном заходе можно уйти?
  21. Из-за большого объема работы пришлось на неделю отложить выпуск еженедельного выпуска "Размышлизмов". Впредь я буду стараться не допускать этого В этом выпуске я хотел бы поделиться своими размышлениями о некоторых конструктивных особенностях ранцев Спирит. Текст статьи - тут
  22. Ну вот, и дошли руки до Размышлизмов. Ну точнее не руки дошли . Вызываются к доске ранцы «ParAAvis» , нью вершен, так сказать. Что не может не радовать, качество упало не сильно. Наличествуют небольшие проблемы с петляющими машинками и незатянутыми швами, но это такое? Что настораживает ? 1. Несколько изменились геометрические пропорции. Особенно это заметно на боковых клапанах запаски ? которые оказались длиннее, чем были, причем довольно существенно. На некоторых комбинациях ранца/запаски приходится делать на них поперечную складку, чтобы закрыть верхний клапан ЗП. 2. Медузу вытяжного парашюта начали ставить опять ивановскую, а не немецкую (в черной изоляции). Ивановская слабее, чем немецкая. Начал я размышлять, на что это может повлиять, и вспомнил одну давнишнюю историю, которая случилась в далеком 2003 году. Тогда мы зафиксировали 2 случая задержки в раскрытии ранцев Спирит. Оба ранца имели ивановские медузы, были давно уложены, в обоих случаях система не была затянута на парашютисте, оба имели короткий предохранительный клапан ЗП. В обоих случаях было четко видно начало раскрытия, начало движения клапанов, но потом раскрытие останавливалось. При легком ударе по нижнему клапану медуза уходила. Пытаясь разобраться в причинах, я сел размышлять. Конструкция ранца Спирит подразумевает зачековку контейнера ЗП, при которой первым на медузу накладывается нижний клапан, потом 2 боковых, потом верхний, а предохранительный клапан подворачивается под низ, под верхний клапан. Такая схема зачековки контейнера запасного парашюта не нова. Ее используют RWS на своих ранцах Vector 3, Vector Micron и тандем системе Sigma, а также Performance Variable в ранце Omega, тандем-системе Omega Tandem. При этом одним из основных плюсов именно такой конструкции называют то, что для открытия контейнера предохранительный клапан не должен ниоткуда выдвигаться. При раскрытии ПЗ он отбрасывается вверх вместе с верхним клапаном ПЗ. Посмотрим на фото этих ранцев: А теперь смотрим на Спирит. Что мы видим? Первое, что бросается в глаза ? боковые клапана ПЗ в той части, где они подходят к узлу зачековки, не подрезаны полукругом, как в Вектора или Омеги, а идут прямо. При этом, после зачековки 2 боковых клапана образуют не горизонтальную линию, как у буржуев, а треугольник, вершиной вверх. У меня возникла по этому поводу теория? Чтобы проверить, берем ранец, укладываем, и дергаем кольцо, снимая раскрытие на видео? И что мы видим: Фото 1. Начало раскрытия. Становиться очевидно, что в момент раскрытия боковые клапана не раздвигаются в стороны ровно, как у Вектора, а сохраняют свою треугольную форму, постепенно смещаясь вверх, и только потом начинают расходится в стороны. При этом они придерживают язычек предохранительного клапана, подвернутый под них. Особенно это видно на левом (от нас) клапане. Фото 2. Узел начинает двигаться вверх, расталкиваемый пружиной снизу. Фото 3. Правый клапан вышел из зачековки. Но левый все еще остается на месте, продолжая разворачивать язычек предохранительного клапана. Фото 4. Оба клапана вышли из зачековки. При этом получается ситуация, медуза давит снизу вверх, в нижний клапан, нижний клапан в свою очередь давит в язычек предохранительного клапана. Для того, чтобы ранец открылся, нужно чтобы отошел нижний клапан, в который с одной стороны давит медуза, а с другой ? вставший ребром пластиковый язычек предохранительного клапана. Фото 5. Язычек проскользнул по нижнему клапану, нижний клапан ничем больше не удерживаемый, откинулся, медуза ушла. Согласно моей теории , зафиксированные нами случаи задержки в раскрытии произошли в том случае, когда язычек таки заклинил на нижнем клапане. Задержка достижима в случае совпадения нескольких параметров ? короткого предохранительного клапана ПЗ, слабой медузы, слежавшейся укладки, определенной комбинации размера ранца и уложенного купола и т.д. Ну так вот ? поделился я своей теорией с товарищами из компании ParAAvis. Долго их убеждал. Даже обещали мне выпустить бюллетень, о контроле минимальной длины клапана. Проект его даже присылали, но потом как-то ? Ну в общем все так и сошло. ПарААвис, к его чести, бесплатно менял медузы, и даже вроде откорректировал лекала предохранительного клапана. Как личный вариант решения возможной проблемы для своих заказчиков я использовал: - замену медузы на более мощную (немецкую), - контроль минимально допустимой длины предохранительного клапана и его ремонт при необходимости, - в спорных случаях я вынимал пластиковую жесткость из язычка предохранительного клапана ПЗ. Вернемся теперь в настоящее... Что мы видим на новых моделях ? замена медузы на ивановскую, изменение геометрических размеров. Изменились боковые клапана запаски, как изменился предохранительный клапан - неясно. На некоторых ранцах он длиннее, на некоторых короче... Все это возвращает нас к той ситуации, в которой мы были в 2003 В дополнение ? ПарААвис решил перенести патрон страхующего прибора на нижний клапан. Не обсуждая это, само по себе довольно спорное решение, хочу заметить, что, подложив патрон под нижний клапан, мы еще более поднимаем его, уменьшая и так небольшой зазор для язычка предохранительного клапана. Вот, в общем такие мысли. Было бы интересно послушать, что думают об этом другие риггеры...
  23. ну как тебе сказать... в теории да, на практике - лишний обьект, щель между боксом и шлемом и т.д.
  24. Зацепление РСЛ за выступающие части камеры, фото, прицела и прочее...
  25. ну, учитывая, что ты точно не знаешь, большо ли он - подбирать укладку - ровнее разлистывать, меньше выставлять его
