me contesto solo...
This is a unique feature of the Silent Eagle, greatly increasing its stealth capabilities at the cost of reducingCFT fuel capacity considerably, which reduces aircraft's combat radius by 180-200 nm (to about 800 nm for A/G missions and 720 nm for CAP missions - using F110- GE-129 engines).
osea.. representa una reduccion en el alcance de 330/370km lo que no es tanto.. considerando la capacidad de reaprovisionamiento.
aunque aclara que usando los GE-119..
y algunas puntualizaciones mas:
Anyhow it seems to be clear, that the Silent Eagle's RCS reduction package is effective against X-band radars, that is airborne radar systems - emphasizing the fact that it's an " A/A only" stealth, which is not optimized against ground based radars
es claro no?... solo en la banda X , por lo tanto , y como bien lo dice, no esta optimizado como "sigiloso" contra radares de superficie..
es un punto bien importante y a tener en cuenta..
me pregunto si los F22, F35 y demas 5º gen tendran limitaciones similares?
Of course for true stealth only coatings and external treatments are not enough, "real" stealth aircraft designs use special internal structures developed for absorbing and dissipating incomingradar energy. To what extent Boeing changed the Strike Eagle's internal structure is not known, however due to the relative shortness of development time and because of the fact that a reotrofit kit (containing CWB equipped fuel tanks, DEWS and coating) is offered by Boeing for existing Strike Eagle aircraft, we conclude that no major internal structure changes (if any) have been made to the Silent Eagle.
este parrafo es mas interesante aun... y explica en cierta forma la razon de ser del SE, ya que aclara que en realidad la capacidad "real" de sigilo no viene solo con los CWB , sino con cambios estructurales que, obviamente, solo se podrian aplicar a aviones de nuevo cuño.
aunque, claro, nada impide que pueda utilizarse estos CWB en cazas existentes que sin lugar a dudas ayudaran a reducir el RCS final..
Speaking about engines, one key feature for true stealth is to significantly lower the engines' heat signature, something which the F-22 Raptor has done already. So far Boeing has no plans for reducing engine heat signature for the Silent Eagle.
y finalmente, el tema de la firma IR de los motores..
esto es algo que , creo, ninguno de los nuevos 5º gen tratan mucho...
por eso el F-22 se sigue considerando como el "verdadero sigiloso"
muy interesante sitio este..
