Problem is not really power, but gas generation and distribution. You dont just simply make plasma from ambient air as far as i understood, i’ll let you know, but quite busy atm writing my book on mirage 4000 + normal work. Their Ramses NG pod also desreves lots of interest. (5cm definition SAR coupled with huperspectral cameras)

The bird have to be shaped for that.

With it’s short nose, frwd projected inlets, closed tight engines, under that form, the Raf is out. LENGHT shld hve been the variable driving the upgrade.

But for what I know…

Interesting that they just acknowledged working on it. It means that they are thinking STEALTH. Oh … shhhuuut. The S word 😮

A good thing however. With a mid generation date of entry (btw the PakFa and the 6th gen US), once again DS have all its chance commercially… Well until the bald heads up there start mixing with the schedule.

Let’s only hope that they won’t miss that opportunity that time.

Plasma, Dupercruise, stealth, active cancellation of visual spectrum, high alt supersonic dogfights, DEW, Cyber, multi-configuration platforms, synergy btw Unmanned/Manned… Wew! The future is much more promising than our usual cable TV programs. Even the Transformers will look like an army of fork armed gentle dwarfs.

One hundred years from now a future historian will find that color photo and it will drive him wild finding documentation.

Let me guess, its name will be Bill something 😀

Negative stability was also present in F-16 and Su-27. It does have impact, I don’t deny that, however, TBH I have no means of implementing that into my estimates. So going estimating F-22 by using F-15 or Rafale by Mirage2k may not be exact, but a) but I don’t have anything better. b)such way of estimating (by ratioing things) is never supposed to be accurate anyway.

Sry but cldn’t stop noticing that.

NegStab = positive trim in your turn model.

Negative trim = negative lift (2PiAlphS) <- you use thin wing basic theo

For a staggered config (tailplane in the wake zone of the wing), you’d need to add a coeff to reduce the negative impact. O.8 by memory. But’ you’d better check the NACA report on that subject and then navigate toward more modern design .I am sure you’d found enough interest doing so by yourself than me digging in my Archives.

And to make happy the Canard’s Boys, you’ll hve to add one also to that config.

To get it accuratly, perhaps you can use the T.O roll of the Grip and so on without the canard and then get a cte for the coeff out of it.

My 2 cents obviously.

I like that one : Su27 VS F15 Clash of the Titans

Gunner wasn’t just to operate the tail gun IIRC. Il-28s used their tail guns to great effect during bombing runs assent against anyone foolish to try to lob a manpad in their ass in Afghan. eason why they tried to field modify tail gun to Hinds in Afghan and gun pod were mounted the other direction

I remember reading about the tail gunner of a Blinder (old Tu22) shooting down a ManPad launched after his plane. Story was from pilots seating on ground during the bombing run !

I don’t understand the meaning of that Post Hallo. Unless you try to make post 4th July headaches more painful.

Ok. There is a Thesis from March 2014 dedicated to Radar registry and target recognition in the Civil Industry using BSR.

Registry is not really new with RAM. Even the Russians have developed analog filters to make the process faster and be less dependents of the Processing speed capability (Jõ ?). Those are to be used in every 5th Gen aircraft. Does it really need hundred of pages to says so ?

What I didn’t see is a stat for the target recognition giving a positive indication of the number of detected contacts on Very low RCS targets .But probably I missed something here or I am of bad mood.

Corrosion issues delays Dutch NH-90 acquisition

92 corrosion occurences in the helicopters, which it attributes to a combination of design and assembly faults and the wrong choice of materials. In some cases, the corrosion was caused by combining materials without isolating them.

NHI immediately set up a task force to find solutions for the problems and has found technical solutions for around 60 per cent of them

The prob with corrosion is what you can’t see, not what inspection will identify. If proper manufacturing methodologies weren’t part of the production standards… Well, never owned an old Fiat* from the 80’s ?

GL to the crew. Let me guess: the next avionics upgrade will be… a crucifix. 😡

It should be noted that the corrosion
analyses in the report are
preliminary and based on visual
inspections only

(part of the edited section – extracted from the report)

EDIT :

That’s even worst !

Extracted from the report:

Widespread corrosion is
found during routine maintenance
inspections of two helicopters with
each about 250 flight hours in saline
environment.

Much of the corrosion occurred
because prevention of galvanic
coupling was not taken into account
in the design. Galvanic coupling of
metals to carbon fiber reinforced
composites leads in almost all cases
to accelerated and widespread
corrosion of the metal when it
comes in contact with a corrosive
environment. Electrical insulation
of the metal from the carbon fibers
by using for instance jointing
compound or sealant prevents the
galvanic coupling and hence the
accelerated corrosion.

absence of sealant,
although the assembly instructions
clearly state that sealant should
have been applied

Time to check who were the subcontractor and crosscheck that they don’t work for the civil industry!

use of materials that are not
resistant to corrosion in salt water
environment or component designs
where the operational use of the
helicopter, like folding of the tail on
ships, was not taken into account in
the design of the structure […] some design details act as
water entrapments in some
circumstances

Improper design parameters (structural studies – geometry).

All corrosion occurrences are classified according to their probable cause. The classifications
used are:
 Wrong design.
 Wrong manufacturing.
 Wrong materials selection.
 Insufficient corrosion protection.

Among the zone affected:

Power plant, transmission and rotors: zone 400

!!!!

– I am even ashamed to have to link this to the name of this company. Sry abt that (but the good old Renault’s weren’t better).
– It’s a rather long post for the news section – Admin, please feel free to relocate it in a more appropriate section

So “Much more!” (read it with glowing eyes) ends up to be Much less!
