PS: wasn't it July 25th ? Yes

Sorry about that mistake in the date, but I can't fool you guys!

To Rago: my mistake, it appears that it was in fact a type IX, the type XI is derivated from it.

1- Which plane?
2- Year of the first flight?
3- Which engines?
4- Power?

:teach: For experts only, good luck!

Is it the "Sperwer HV" from Sagem?

HorsePower · Post by **HorsePower** » 01 Sep 2005, 21:39

hint n°1: As you can see, this is an manned aircraft, not a drone (UAV).

hint n°2: Have a look on the flag.

If you are not able to find it, just ring me, I will help you!

It's a Microturbo Microjet 200

The Microjet programme was started in the early 80's by Microjet SA in France, a subsidiary of Groupe Creuzet, an aircraft component manufacturer. The program was initiated by Jean-Gabriel Bayard, then president of Microturbo. The Microjet was aimed at the military training market. First flight of a wooden prototype F-WZJF occured on 24 June 1980 with Jacques Grangette at the controls. He was also the one heading the design group. First flight of a pre-production aircraft (F-WDMT) took place on 19 May 1983. The third prototype had underwing hardpoints.

The Microjet prototypes were powered by two Microturbo TRS-18-1, each rated at 293 lbst, uprated automatically to 326 lbst if the other engine should fail during take-off. The production aircraft was to be powered by the TRS-18-2 rated at 405 lbst.

The structure was a classic semi-monocoque, gear was retractable (electrical actuators), cockpit unpressurized, seats staggered by 22in, avionics was IFR and included the military extras such as UHF, TACAN and IFF.

The small vertical fins on the tail were added in 1989 to address spin recovery issues.

Poor performance due to inadequate powerplant made the aircraft inappropriate for its intended market.

I found it with a bit of luck. I was reading in an old Flight International dated 14/8/1982. On the frontpage is a nice picture of the prototype F-WZJF.

Well done my friend!

Poor performance due to inadequate powerplant made the aircraft inappropriate for its intended market.

Indeed, propellent efficiency is around 38% only! What a damn fuel gluzzer, even worth than the Concorde!

Your turn, Koen!

My question:

What is the technical difference between the inboard and outboard engines of the BAe-146/RJ?

Koen

HorsePower · Post by **HorsePower** » 05 Sep 2005, 22:27

I would say there isn't hydraulic pumps on outboard engines.

Regards

Seb.

realplaneshaveprops · Post by **realplaneshaveprops** » 05 Sep 2005, 22:34

Yep, but that's true. But what's on the outboards, that isn't on the inboards?

Koen

HorsePower · Post by **HorsePower** » 05 Sep 2005, 23:26

Could it be that IDGs are fitted on outboard engines?

Seb.

realplaneshaveprops · Post by **realplaneshaveprops** » 06 Sep 2005, 16:14

Correct, your turn again Horsepower.

The inboard engines of the BAe-146/Avro RJ have an engine-driven hydraulic pump, the outboard are fitted with an IDG. When building-up an engine to Quick Engine Change standard (QEC), you can choose: installing the hydraulic pump, or the IDG.

Some acronyms now:

What does mean VTO (Boeing)?

Don't hesitate to ask questions as ATA, loc, etc...

Vertical Take-Off?

HorsePower · Post by **HorsePower** » 06 Sep 2005, 21:16

:shakehead:

regi · Post by **regi** » 06 Sep 2005, 23:01

what no no, it is vertical take off. Double "f".

HorsePower · Post by **HorsePower** » 06 Sep 2005, 23:17

No, I'm looking for a system inside the aircraft. BTW, I don't know that much of Boeing Commercial Airplanes "VTO" capable

.

Try again, folk!

Yes TSBC, your turn.

Do you remember incidents with fuel spreading on the taxiway due to VTO faillure?
