FAA Says Drones and People Don’t Mix

An FAA study released last week concluded that people on the ground are susceptible to three dominant kinds of injuries should they be unfortunate enough to meet up with a drone, especially a unit’s unprotected propellers. Those risks include blunt force trauma, the most significant contributor to fatalities, lacerations and penetration injuries.

the inlets look like quite similar to that of the J20

Don’t worry. You still have many years to rant

To rant:
synonyms: fulminate, go on, hold forth, vociferate, sound off, spout, pontificate, bluster, declaim

You get the picture I guess.

@Ryan:

Technically it isn’t a ramjet though, it’s a VFDR. The propellant is solid, so no volume constraint.

Launcher exposure? Drag? Think you may be overestimating the extra drag of a few small ram intakes.
Quick reply to this message Reply

The volume constraint is for the carrier aircraft. Think at the added volume of the inlets, hence larger fins, hence heavier body (structural needs) hence larger size etc…
In the 80’s, solid propellant tech were what they were and the Ramjet road was a brilliant choice. Today, solid propellant efficiency has increased by a factor of somewhat two and today (well… next tomorrow) , dualphase propellant (solid to liquid) could even better the overall power efficiency ratio.

Think that the rocket model is the most efficient propulsion system: no external drag added, no propulsion drag, lower aero impact with lesser structural needs and, at the end, more compact missile in term of diameter.
Gone are the days of the mammoth size Genie missiles 😉

So they are here to choose for a fighter and you want them to buy a plethoric armada?

Hint: who recently named the F35 an F/A/B/RC/EW/AWAC 35?
Would Seems perfectly suited here, no?

I find this whole Meteor thing very funny/ironic. Anyone that followed the project knows that FMRAAM was designed for Typhoon and Typhoon was designed for FMRAAM (now Meteor). So whilst it is a beautiful thing to have the two coming together, it is decades late.

True.

Also, aerodynamically, the ramjet is not in theory the most efficient solution for a missile. That statement is false (think volume constraint, propulsion system inherent drag (compression and expansion drag/inlet drag), carrier volume constraints (hence lower kinetic potential at launch) etc…

I have already mentioned earlier the increased time of launcher exposure due to the range of the weapon that also restricts the time on station of the launcher etc…

You do not compensate an older airframe technology with a Meteor.

The missile being however a formidable ace card in 4th gen vs 4th gen scenarios (think Asia/ Middle East / Sth Am, Africa…).

You are on the verge of paranoia. I have no agenda against Dassault; once for all put that into your mind.

And stop personifying every subjects that you don’t like. Your mention of his abduction sounds rather insulting under the circonstances as if he was writing about green men and unicorn.

Malbrunot didn’t invent it either. Not his own range of expertise.
The question that should be posed is how the hell the Fr secret services and the Fr administration could have leaked (hence owned) such info?
That’s the real concern.

Covert elint ? Remember that it was about the same time the 71 was retired.

That rotor system has been seen already somewhere else.
