Something Whining over EGDM/SPTA
What on earth is making that awful dreadful whining racket over EGDM/SPTA or more importantly my house?
It sounds like a large bumblebee trapped in a big tin can. Its definitely got wings but is just incessantly going around and around, getting nowhere and before anybody says move...... in 30 years of piloting and living in this house I have never heard anything so irritating more importantly, its on my 2 weeks off! - I'm sure nobody minds the sound of a real aeroplane/Helicopter engine/s but that thing just sounds like a high pitched sewing machine and is just totally infuriating.

Certainly sounds similar - I just wish it would foxtrot oscar and annoy Timmy or whatever his new gang are called or better still Mr Bliar.

In your experience I'm not surprised!
In mine it is an irritating whine, right over my house; alien to aviaton.

Was it strictly necessary to use a 2-stroke lawnmower engine to power it?
It sounds only slightly less annoying than those godawful powered paragliders. Can't honestly see the appeal is - dangling from a parafoil sat atop a chainsaw with prop attached, being overtaken by arthritic ants and the occasional continent.

I think I could cope with a good old 2 stroke or even the throb of a pair of
CT7-8A's but this thing sounds like a high pitched chain saw with little or no pitch change.

Its not a two-stroke its a Wankle and yes it does make an anoying buzz.
I don't know where you have been Mostafa but its been flying out of Boscombe for a month now and so some of us are begining to mentally switch its noise off.
It must be really dangerous though, as on its first flight out of Boscombe it was sheparded by a Gazelle, now when its anywhere in the circuit everything else flying out of Boscombe either foxtrot oscars or sits on the ground until its safely out of the way.
As for the Gaza Strip my one memory of the place was the constant noise of two-strokes at altitude and still being able to hear the UAV when it was 40 miles away.

I'd be a bit worried mate if it's flying over your house all of the time...when you see the black Range Rover pull up run like buggery...

From what has been described it is most probably a Watchkeeper UAS. The annoying noise is not generated by the engine but by the prop tips. The engine operates at such high revolutions that the prop tips are close to the speed of sound.

Thx - I feel so much better now, knowing that it's not the Wankel engine (I had a car once that had one of them (RX7)) but, the tip speeds of the propeller. Mind you, saying that, the children must have broke their toy because I didn't hear a peep out of it yesterday! Maybe it's gone into stealth mode in search of all those virgins.
It's made my well earned rest so much more fun; it's given me a new lease on life and I am so looking forward to my next break and to annoying all those seagulls and fish, again, next week!

Is the noise all part of the psy-ops strategy? We'll fly it over the bad guys all day and all night until they get fed up with the noise and offer to give up their guns if we just take it away?

Not exactly stealthy, wonder if the undetectable radius will be greater than the sensor useful range. The chaps on the ground usually get upset if you tip the bad guys off and your tasking dries up pretty quickly.
