Para el piloto militar, la capacidad de percibir amenazas alrededor de su avi\u00f3n, es la diferencia entre la vida y la muerte. Para brindar a los aviadores militares acceso inmediato y visualizaci\u00f3n de los datos, as\u00ed como la inteligencia que necesitan para aumentar la capacidad de supervivencia y cumplir sus misiones,, empresas como Collins Aerospace han trabajado para mostrar los datos en el lugar m\u00e1s efectivo para el piloto: frente a sus ojos.<\/p>\n
For the military pilot, the ability to perceive threats around their aircraft is the difference between life and death. To give military aviators immediate access and visualization of the data and intelligence they need to increase survivability and accomplish their missions, companies like Collins Aerospace have worked to display data in the most effective place for the pilot \u2013in front of their eyes.<\/p>\n
The personal-fit headgear display system utilized by the aviators flying America\u2019s next-generation F-35 joint strike fighter, offers unparalleled situational analysis, visual accuracy, and flight safety. To do so effectively, it needs to be custom-fit to the pilot, and any wear and tear that compromises that fit can have negative impacts on the wearer\u2019s ability to fly their mission.<\/p>\n
The Modern Battlespace<\/em>\u00a0recently talked with Arthur De Ruiter\u00a0<\/em>and\u00a0<\/em>Dustin Vagedes of Collins Aerospace, about how the F-35 headgear outperforms helmets from the past. They also explained why wear and tear can be detrimental, and why maintaining these personalized fit helmets can be challenging.<\/p>\n The Modern Battlespace (TMB):<\/strong>\u00a0How are<\/em>\u00a0F-35 helmets and visors superior to prior models? What makes them unique?<\/em><\/p>\n Arthur De Ruiter:<\/strong>\u00a0The F-35 helmet and visor system is truly an engineering marvel that represents today\u2019s fifth-generation warfighter. The key difference between the F-35 helmet and a traditional fourth-generation warfighter helmet used on the F-16 is that all the flight and mission data is presented to the pilot on a display, mounted to the helmet.<\/p>\n \u201cIF THE PILOT LOOKS AROUND IN CERTAIN CONDITIONS, THEY DON\u2019T SEE THE COCKPIT OR EVEN THEIR LEGS\u2026 ALL THEY SEE ARE THEIR SURROUNDINGS LIKE TERRAIN\u201d \u2013 ARTHUR DE RUITER<\/p><\/blockquote>\n In addition, the helmet is connected to six infrared cameras located around the aircraft, providing a 360-degree view and unprecedented situational awareness. If the pilot looks around in certain conditions, they don\u2019t see the cockpit or even their legs. All they see are their surroundings like terrain, with the flight critical and mission data projected inside the helmet.<\/p>\n Dustin Vagedes:<\/strong>\u00a0Indeed \u2014 the F-35 helmet is unlike any other in history. The Collins Aerospace F-35 Helmet Mounted Display System (HMDS) was designed to realize and exploit a true pilot-to-machine union.<\/p>\n \u201cTHE CONNECTION OF THE HMD TO THE AIRCRAFT IS UNIQUE FOR EACH PILOT\u2026 TO ACCOMMODATE TORSO LENGTH AND RANGE OF MOTION CHARACTERISTICS.\u201d \u2013 DUSTIN VAGADES<\/p><\/blockquote>\n Weighing in at around five pounds, this system hosts an on-visor, bi-optical Heads-Up Display (HUD) to include digital night vision and imagery overlay from the aircraft\u2019s Distributed Aperture System (DAS), set to each pilot\u2019s interpupillary distance for optimal display quality. The connection of the HMD to the aircraft is unique for each pilot through different length interface cables to accommodate torso length and range of motion characteristics.<\/p>\n TMB:<\/strong>\u00a0Obviously, all equipment requires maintenance.<\/em>\u00a0How does<\/em>\u00a0wear-and-tear affect an F-35 pilot\u2019s helmet and visor? Does this headgear last a long time, or will it eventually deteriorate after a few years?<\/em><\/p>\n Arthur De Ruiter:\u00a0<\/strong>Inside the helmet shell are custom-milled pads that generally experience normal wear and tear. Other than being exposed to sweat or hair grease, they usually last a long time if the helmet is well fitted. Visors typically get scratched by frequent handling and need to be replaced more often. That can be a challenge because they must be custom-trimmed to fit the oxygen mask.<\/p>\n \u201cANYTHING THAT CREATES MINIMAL SPACE BETWEEN THE CRANIUM AND THE CUSTOM MILLED PADS CAN CREATE A PROBLEM OVER TIME, POTENTIALLY REQUIRING A HELMET REFIT AND UPDATED OPTICAL CALIBRATION.\u201d \u2013 ARTHUR DE RUITER<\/p><\/blockquote>\n The need for helmet refitting becomes really important when physical changes are happening with the pilot, such as weight or hairstyle changes. Anything that creates minimal space between the cranium and the custom milled pads can create a problem over time, potentially requiring a helmet refit and updated optical calibration.<\/p>\n Over time, the pilot will notice if there are any issues by feeling uncomfortable \u201chot spots\u201d or even double vision, which can lead to fatigue, headaches, and long-term neck injuries. It is important that pilots immediately report any of these issues to their life safety equipment teams, so they can contact Collins Aerospace to solve any fit issues.<\/p>\n Dustin Vagedes<\/strong>: These helmets have proven to be quite resilient.\u00a0<\/strong>The F-35 has now logged over 400,000 flight hours to date and our 2,000-plus HMDs custom fit and delivered to date have held up well. The HMD system was designed to be operated and maintained in the most austere conditions our warfighters may be operating within. With this in mind, the HMD was designed with seven-line replaceable units (LRUs), that can be serviced or replaced in the field as necessary.<\/p>\n \u201cTHE HELMETS GO THROUGH A LOT DURING THEIR LIFETIME [WHICH WAS] CONSIDERED DURING THE DESIGN OF THE HELMET\u2026 TO REDUCE THE NEED FOR RETURNS TO THE FACTORY FOR MAJOR REPAIRS\u201d \u2013 DUSTIN VAGEDES<\/p><\/blockquote>\n The helmets go through a lot during their lifetime. Between missions, they are stuffed in the pilots\u2019 helmet bags and stored in their flight lockers. Helmet maintenance and cleaning are often performed by schedule-saturated technicians, who may be stressed with meeting their assigned time-sensitive missions. Pilots can even bang the helmets against things in the cockpit while doing aggressive head turns while checking their \u201csix\u201d. All these things were considered during the design of the helmet and factor into continuous design improvements to reduce the need for returns to the factory for major repairs \u2014 saving our customers and our end users money in the long run.<\/p>\n The helmets hold up quite well over time. It\u2019s the visors that are most likely to need replacement since they\u2019re supposed to be clean and clear but are exposed during use and storage. Any scratches on the surface of a visor might become an annoyance to a pilot even if they don\u2019t affect helmet functionality.<\/p>\n TMB:<\/strong>\u00a0What has the process traditionally involved for replacing a pilot\u2019s helmet and visor? Can they just use replacement parts, or is there a process that must be followed?\u00a0<\/em><\/p>\n Dustin Vagedes:\u00a0<\/strong>The previous helmet-mounted display systems have typically been built around a fairly universal helmet shell and require extensive modifications to replace and\/or reconfigure for their specified use and reuse.<\/p>\n The Collins Aerospace F-35 HMD\u2019s consistent configuration and integrated design provide a repeatable fit as replacement parts are installed.<\/p>\n The custom-milled liner and visor files are retained indefinitely and are provided to the end-user to further ensure continuity of the performance and fit. These replacements are typically provided by the services-life-support personnel who follow the OEM maintenance process to return a helmet to service, after being trained or re-trained by Collins Aerospace.<\/p>\n Arthur De Ruiter:\u00a0<\/strong>In the current fitting process, pilot cadets will get their new helmet fit at a Pilot Fit Facility, typically at a US Air Force Base like Luke. This is a two-day process and after they have been fitted, they go straight into their extensive training program. Unless there is a major problem with the helmet seen during training flights, we typically do not see the pilot again.<\/p>\n \u201cIF ANYTHING HAPPENS TO THE HELMET\u2026 THEY WOULD NEED TO GO THROUGH THE ENTIRE FITTING PROCEDURE AGAIN, WHICH MEANS RETURNING TO AT PILOT FIT FACILITY IN THE US.\u201d \u2013 ARTHUR DE RUITER<\/p><\/blockquote>\n Once they become deployed at their home base and fly extensive hours, they are on their own to work with the services-life-support teams. If anything happens to the helmet that affects the perfect fit beyond what can be resolved with a simple replacement part, they would need to go through the entire fitting procedure again, which means returning to at Pilot Fit Facility in the US. Fortunately, Collins Aerospace has developed a technology that will get pilots back in the air sooner, by bringing the solution to the customer.<\/p>\n
