F-35C might have to redesign its nose gear (il faudra peut-être redessiner le train avant du F-35C suite aux essais en mer)...http://alert5.com/2017/01/05/f-35c-migh ... nose-gear/https://insidedefense.com/daily-news/pe ... s-possible
1. l'article de ID n'est pas dispo à la lecture pour tout le monde.
2. et quand on a la possibilité de le lire, ton propos initial est "très fortement nuancé":
The short-term actions are slated to begin in early 2017 and will take about two to six months to complete, according to the paper. The actions include implementing improved and standardized restraint procedures for pilots and flight testing later this month on the effects of a reduced RRHB release load. VFA-101 will evaluate both the restraint procedures and a reduced RRHB load during its next carrier qualification period in the spring, the paper reads.
In late 2017, medium-term actions ranging from six to 12 months to complete will begin. These include HMD symbology, nose landing gear modifications and pilot motion modeling. Regarding symbology, "Options are being considered that would simplify the information displayed to the pilot during and immediately after catapult launch, to make it easier for the pilot to interpret flight-critical data," the paper notes. One of the problems here is the contractor doesn't think there is enough time in the system design and development phase to demonstrate this in simulation, according to the paper.
Long-term actions would not begin until 2019 and would take 12 to 36 months to complete. These include RRHB geometry that would reduce compression of the nose gear strut before launch. This course of action may require ship modifications, according to the red team.
Another long-term action is a nose landing gear redesign. A redesign is not being pursued because of highly constrained design space.
"A redesign could incorporate all the benefits of the advanced modeling efforts, but is expected to require a multiyear effort to re-qualify a major redesign," according to the paper.
Pas de redesign du train avant.
