"Helmet system replaces heads-up display on F-35s"
You are dead right - but then the assumption is you surprised nobody and
you are engaged by the killing defenses which is one reason why a clear decision needs to be made if you are focused on stealth as a strong case leading to some degree of invisibility that net's some degree of surprise against a spectrum of threats or a point design that works only on one thing. In short use cruise missiles in this case. If you are flying with stealth you may want to close off the canopy if you can, if you are being searched out by lasers then your eyes could be hurt before the systems and sensors would be hurt, in such a progression. Think back on the problems with laser designators and the various intentional and accidental bindings of personnel - this resulted in laser glasses that were to protect the eyes in certain known utility frequencies - but now the power is up and the spectrum expanded. The aluminum canopy could actually be a glass/plastic one that when a strong laser touches it turns immediately opaque and the helmet system becomes the primary flight reference instrument set.

So you put the metal canopy of it, and instead of blinding you, the laser blinds the plane's cameras...and then, as you are descending under your parachute, the laser gets around to blinding you also. Then it sets the chute on fire. Pat |

This is practical now; B-1B's use electro-optical material in the windscreen to turn it opaque in a split second if a nuclear flash is detected (I assume the B-2 has the same feature) to prevent the crew from being blinded. The same technique could be used for laser attack protection. More than lasers, microwave weapons might be the major threat in the future. Pat |

you bet and it could be also used in glasses or visors for troopers

Benjamin We're talking several generations of difference here in terms of what the HMDS is offering. It's like saying the ME-262 already had jet engines in 1945, so what's new about the F-22.

An old buddy who has been working out of Ft. Worth with the design team was telling me at one of the Rat reunions about the integrated video cameras mounted in the skin that project into the helmet based on where you are looking. If you turn to a place where the airframe is in the way you get video from the camera on the other side of the structure so your view is unimpeded. If you look at the wing you see video from the bottom side so you essentially look right through it. Look at the floor and you get the bottom fuselage video so you see what is beneath your feet.

Ed Rasimus Fighter Pilot (USAF-Ret) "When Thunder Rolled" www.thunderchief.org www.thundertales.blogspot.com Just like in one of the modes in Combat Flight Simulator 3;-) Strange feeling like lying on the belly along the fuselage and looking thorugh a prop hubcap, even for somebody who never flew the real thing. Wouldn't a helmet-mounted sight coupled with a good EO/FLIR/laser pod turret be good enough? Best regards, Jacek |

We're talking several generations of difference here in terms of what the HMDS is offering. Well, the difference is not *that* huge. The only thing that is done in the F-35 is to move the complete display part from the HUD to the HMDS (which IMHO does make sense, I wonder why this hasn't been done before already). Benjamin |

It all got started in South Africa of all places; they hooked the tracking systems of their Kukri IR AAMs into the helmet so that the pilot only had to look at the target to slew the optics of the missiles around and let them lock onto it. From that point forward, it was simply a matter of getting the mass of the helmet down to the point where it wouldn't snap the pilot's neck if he had to eject, while adding more and more to its capabilities. I'm sure our Huey gunner's helmets with their automated gun-slewing mechanisms also played a big part in the overall history; but you don't pull high Gs in a Huey unless you crash. Pat |
