Шлем пилота
Дисплейный шлем для пилота F-35 Helmet Mounted Display System (HMDS)
Это шлем, который позволит пилотам реактивных истребителей пятого поколения «видеть через кабину» самолёта. Снаряжение разработано для истребителя-бомбардировщика F-35 и в настоящее время тестируется научно-исследовательским отделом Министерства обороны Великобритании в Уилтшире.
Вместо обычного дисплея на приборной панели синтезированное компьютером изображение будет подаваться прямо на визоры пилота, снабжая его также подсказками, необходимыми для полёта, навигации и ведения боя. Принципиально новой технологией стала реализация возможности видения в инфракрасном диапазоне, то есть с помощью шлема пилот сможет видеть даже ночью. Шлем позволяет автоматически переключаться между видеорежимами. Фактически, самолёт сможет стать «прозрачным» для пилота. Также шлем является своеобразным командным центром: высокоточное целеуказание всего бортового оружия завязано на движения головы и глаз лётчика.
Пока создан только опытный образец. Разработкой модели занимаются британские компании Vision Systems International и Helmet Integrated Systems Limited.
Израильская компания Elbit Systems специализирующаяся в разработке и модернизации различных видов вооружений и её американский партнёр, компания Rockwell Collins, будут выпускать пилотские шлемы для истребителей F-35C. Шлемы будут добавлены в стандартную комплектацию самолётов с 2016 года.
Helmet-mounted display system[edit]
VSI Helmet-mounted display system for the F-35
The F-35 does not need to be physically pointing at its target for weapons to be successful.[273][357] Sensors can track and target a nearby aircraft from any orientation, provide the information to the pilot through their helmet (and therefore visible no matter which way the pilot is looking), and provide the seeker-head of a missile with sufficient information. Recent missile types provide a much greater ability to pursue a target regardless of the launch orientation, called "High Off-Boresight" capability. Sensors use combined radio frequency and infra red (SAIRST) to continually track nearby aircraft while the pilot's helmet-mounted display system (HMDS) displays and selects targets; the helmet system replaces the display-suite-mounted head-up display used in earlier fighters.[358] Each helmet costs $400,000.[359]
The F-35's systems provide the edge in the "observe, orient, decide, and act" OODA loop; stealth and advanced sensors aid in observation (while being difficult to observe), automated target tracking helps in orientation, sensor fusion simplifies decision making, and the aircraft's controls allow the pilot to keep their focus on the targets, rather than the controls of their aircraft.[360][N 3]
Problems with the Vision Systems International helmet-mounted display led Lockheed Martin-Elbit Systems to issue a draft specification for alternative proposals in early 2011, to be based around the Anvis-9 night vision goggles.[361] BAE Systems was selected to provide the alternative system in late 2011.[362] The BAE Systems alternative helmet was to include all the features of the VSI system.,[363] however, adopting the alternative helmet would have required a cockpit redesign,[364] but in 2013 development on the alternative helmet was halted due to progress on the baseline helmet.[365]
In 2011, Lockheed Martin-Elbit granted VSI a contract to fix the vibration, jitter, night-vision and sensor display problems in their helmet-mounted display.[366] A speculated potential improvement is the replacement of Intevac’s ISIE-10 day/night camera with the newer ISIE-11 model.[367] In October 2012, Lockheed Martin-Elbit stated that progress had been made in resolving the technical issues of the helmet-mounted display, and cited positive reports from night flying tests; it had been questioned whether the helmet system allows pilots enough visibility at night to carry out precision tasks.[368] In 2013, in spite of continuing problems with the helmet display, the F-35B model completed 19 nighttime vertical landings onboard the USS Wasp at sea,[369] by using the DAS instead of the helmet's built-in night vision capabilities, which offer at best 20/35 vision.[370]
In October 2013, development of the alternate helmet was halted. The current Gen 2 helmet is expected to meet the requirements to declare, in July 2015, that the F-35 has obtained initial operational capability. Beginning in 2016 with low rate initial production (LRIP) lot 7, the program will introduce a Gen 3 helmet that features an improved night vision camera, new liquid crystal displays, automated alignment and other software enhancements.[365]
In July 2015, an F-35 pilot commented that the helmet may have been one of the issues that the F-35 faced while dogfighting against an F-16 during a test; "The helmet was too large for the space inside the canopy to adequately see behind the aircraft. There were multiple occasions when the bandit would've been visible (not blocked by the seat) but the helmet prevented getting in a position to see him (behind the high side of the seat, around the inside of the seat, or high near the lift vector).
