Looking great for her age!
Edge ZK-ZAI gone. Australian gain.
This I0-540, 350hp, powered aircraft joined the US register as N78L in May of 1998 and was cancelled at the end of July for it to become ZK-ZAI on 25-09-1998 for the Hawker Trust of Auckland.
PZL M18B Dromader cancelled.

They look pretty cool, don't they?
But 76500 ft looks even cooler:

Interestingly though, 42000 ft still looks pretty amazing:
ZK-BWL returns.
In mid December of 1970 Cookson Airspread of Wairoa were the operators with a transfer to Manawatu Aerial Top Dressing Co Ltd on 23-06-1975. It was withdrawn from service in June 1977 and stored at Feilding and its registration was cancelled on 03-04-1991.
Jat among the world’s safest ... again
Meanwhile, Jat has an uphill battle with finances although big changes may be ahead. More news about this will be published on the blog soon.
Question time # 26 solved.
I believe the "RJ" in the FRJ registration comes from the first two initials of one of the syndicate members.
The nose in the background is that of a Titan Tornado.
Will it blend?
Seems like, yes it did :)
Created with the latest iRhino alpha.
Changes:
* Placeholder engine nacelles added.
* Rudder added
I was reading today the book "Fluid dynamic drag" a bit and got kind of inspired: canopies and wind shield discontinuity contributes very much to the drag coefficient of the fuselage. Not only the laminar nose seems important, but all kinds of places where something ends and something else continues are sources of waste of engery.
So if the plane is completely faired with no discontinuity of any kind, theoretically the drag coefficient should be very low.
In this picture, the engine nacelle placeholders are just placeholders, because they are not yet accurate airfoil, and it has not been taken into account that in Rotax engines the propeller shaft is not in the middle of the engine, but almost on the top of the engine, this creates a fairing that has the lower side turned up a bit and is therefore not completely symmetrical.
The engine nacelles may need to be moved outwards, otherwise there is not enough clearance between the fuselage and the propeller arc.
I was also reading one day some NASA tech paper about wing tip mounted propellers. I have not drawn such things to this picture, but I may add it later - small brushless DC motor on each wing tip lowers the induced drag quite a bit according to the tech paper (although on high aspect ratio wing the effect is not that radical as on with a low aspect ratio wing that would otherwise be poor).
Potential issues for placing engine nacelles on wings (which seems pretty necessary for a twin, after all, may be the least bad compromise) and blending are the followings:
* the wings take a lot room to build (because they are very long)
* making the mold is difficult, because it has to be done from CNC cut pieces and glued together
* moving the center section to airport or transporting it in a container may be challenging, because if the area up to engine nacelles is continuous part of the center section and not separatable, it means that this is basically wider than the width of the container, shipping the plane to another continent might be a challenge (it seems that it would need to be flown like the design point has been set)
New flights to Pula
Robinsons at Christchurch Friday 28th
Above is ZK-HMW2 c/n 2555 on the Helipro pad. This was a new import by Wing & Rotor & registered on 05-12-1995 for delivery to Marlborough Helicopters (listed to them on 10-12-96). It then went to the New Plymouth Aero Club from July 2000 until going to Helirange Helicopters of Ohope in September 2001. By May 2003 it was with Karamea Helicopters and November 2006 had it with Karamea Country Freight of Westport. On 03-09-2008 it was registered to CHL Investments of Christchurch.
And as mentioned in an earlier blog the R44 c/n 0630 has indeed become ZK-HAB2. It was registered to Maruia Springs Thermal resort on 19-11-2008. Given its US airworthiness certificate on 16-07-1999 as N7114A it was cancelled on 18-06-08 for export to NZ, whilst under the ownership of Kevin Farmer of Lodan, Ohio. Hard to see in this cramped hangar shot is the "Maruia Springs" stylised script on the fuselage side.
Pula AirportLarge potential as new flights announced
Recent flights to Belgrade proved to be very popular from Pula with load factors averaging around 75%, which is a good result for an ATR72 aircraft which operated on this line. Jat Airways and Pula Airport have signed an agreement for new flights to be operated to the coastal Croatian town and Serbia’s capital in the summer months, if Jat is financially able to operate at the time. Flights between Belgrade and Pula were the first scheduled flights between the two countries following the civil war. It showed that Croats had high interest in travelling to the once Yugoslav capital while Serbs had the desire to relax on the Croatian coast. German tourists head tourist arrivals to Istria. Berlin offers a high traffic potential which would be supported by strong local demand. Stockholm is currently served to Pula during the summer season. Scandinavian countries, especially Sweden, are regarded as the most promising markets to develop direct year-round connections. This line would also benefit from by strong local demand. There are currently no direct flights from Pula to Madrid. The number of visitors from Spain to Istria is rapidly growing and Madrid, as a destination with high traffic potential, would be a promising route. Substantial domestic traffic to Madrid can also be anticipated. The city of Dublin with its phenomenal economic growth is considered as one of the most popular destinations. It is an attractive destination tourist-wise for locals and for the broader catchment area as well. Croatia Airlines has announced that it will commence flights to Paris, London and Barcelona next year however details about this can be read tomorrow.
2 million passengers pass through Zagreb
Gone offshore. Koala ZK-IHS
It became N119JT with Skyrunner Aviation Inc Trustee of Wilmington, Delaware on October the 7th; the day following its NZ cancellation.
It has been replaced at Heli Solutions by the Agusta AW119 Mk11 ZK-ISR c/n 14710.
Three turbos in Subaru EJ22

Pretty interesting system built around the Subaru.
HALE
Usually nobody flies higher than about 40000 ft. If you look out from a commercial passenger aircraft's window, what you see is blue. You can don't even see clouds very well since you are too high to see them closely and you are too low to see the curvature of the Earth and blackness of space. And the publicly available photography from that altitude is very limited, you don't really get to see even virtually how it looks like up there.
There are some interesting videos about balloon flights to high altitude in Youtube. The balloons go to about 80-100 kilofeets. According to videos, that looks already almost like space. Couple of examples:
Long Trail School High Altitude Balloon at Youtube
Nevada BalloonSat at Youtube
The view is so amazing that I feel it odd that nobody has started to carry people to near space experience with high altitude aircraft. Someone offers MIG-flights, but that is just a ballistic jump there from supersonic flight. Aircraft that can loiter in that altitude would give a whole different experience, it could stay there longer than just minutes.
That kind of aircraft would be impossible someone might say? Not so black and white. There are couple of HALE UAVs around which can go this high. And if you for example look Scaled Composites Proteus which can reach 70000 ft, if you'd replace the telecommunications load from the center section with space grade pressurized passenger cabin, the plane could lift several people at one time to the abovementioned altitude.
According to material I have been seeing from high altitude balloons, it seems like the sky is starting to look like space from about 60000 ft upwards. You need afterburning jet engines to go that high? Not necessarily. Look at for example Burt Rutan's UAV that had twin turbocharged modified Rotax 914 (with fuel injection). It was designed to have positive climb rate at 63000 ft. Seems feasible with piston engines in other words. The company that did the Rotax-conversion for the Scaled Composites UAV, have done triple turbocharged and twin turbocharged versions of the Rotax. The triple turbocharged Rotax is usable to over 80 kft, however, the installation looks really complicated (and the biggest turbo is so huge that must be from a truck).
Tecnam P2006T
www.aidaa.it/3-2008/P2006_corr.pdf
Interesting detail with the used Rotax 912S is that it provides actually better thrust at takeoff and climb than same horse power with a Lycoming engine (because the engine nacelle has smaller frontal area and the propeller rotation speed is lower).

Pacific Aerospace 750XL ZK-SWA
Kiwi Air's fleet includes 750XL's ZK-FNZ, ZK-JBC, ZK-XLA and ZK-XLB plus Reims/Cessna Twin Caravan ZK-XLC which is apparently operating somewhere in Alaska and Cresco ZK-LTP in Australia!
Does anyone know how ZK-SWA left NZ, or was it built in the USA? The NZ Customs website has it listed so perhaps it left NZ around October 2007 to be in Cork by 01Nov07.
Ambling at Ardmore
Helicopters were well represented with Robinson R44 ZK-HQF/2 and Robinson R44 ZK-HJU/4 both outside. Coromandel based Robinson R44 ZK-IAY was beating the helicopter circuit.
A couple of foreign registered aircraft were also on the field, check out www.mrcaviation.blogspot.com.
Skopje AirportEuropean market underserved
Trends show that direct flights to German cities could be very profitable from Skopje. There is a concentration of Macedonians in Berlin, Bavaria, Hamburg and the Ruhr. 62.295 Macedonian citizens were living in Germany in 2006, although Macedonian sources claim the true number of Macedonians to range from 75.000 to 85.000. As a result daily flights to Berlin, Frankfurt and Munich could be potentially profitable. Flights to Belgrade have managed to captivate many travellers from Skopje which are now choosing to transit through Belgrade onto further destinations. This has also been seen by the increase of flights on behalf of Jat Airways to the Macedonian capital. Most passengers continuing from Belgrade continue to London and Paris. There is such a large numbers of Macedonians continuing their flights to the capitals of the United Kingdom and France that 3 weekly flights from Skopje would be profitable to both. In France there is also a significant Macedonian diaspora totalling 15.000. Developing business cooperation and a large Macedonian population in Denmark (12.000) could make 3 weekly flights from Skopje to Copenhagen profitable. Also, it important to remember that all of these flights could be operated via Ohrid, Macedonia’s second hub, which could further increase passenger numbers on flights, although this would depend if the Macedonian Aviation Authority would allow foreign airlines such a practice, most probably not however there have been some cases where they have, for example Jat Airways operated from Skopje to Belgrade via Ohrid.
New variant of the shape I have been thinking about
The idea is that the fuselage center section blends into wings like on blended wing body, but it only forms a minor portion of the shape, high aspect ratio wings continue from the blended part and there is a tail in the rear. I have not drawn this as I was thinking because I have been thinking either V-tail or T-tail. This picture doesn't yet have a rudder.
Now the difficulty is that I have hard time on getting the Rhino do what I think. The loft is challenging, because it follows airfoil shape, it follows the configuration and contour from the top I was thinking, but the problem is to vary the airfoil shape in the center section so that the transition from the right side to the left side is smooth and more circular than in this thing where it is pretty sharp (the sharpness there is completely unintentional and will go away as soon as I figure how to loft this thing properly).
The wing tips did not loft as I planned, and also the elevator has wrong airfoil shape in the tip, the scale2D produced results I was not planning to get. There is still something to learn in Rhino. I need to ask from maybe Jani tomorrow how to do this right.
Question time # 26
Just the type for a starter ; then maybe what model ; then you can add a registration:
Once that is sorted; what will the nose in the background belong to when it is completed ?
ADDITIONAL CLUE (maybe) Added 25-11-2008.
There is something special about this inexcusable extravagence !!!
More on the Zlins down South.
Alexandra Z-37S - I happened across these today. The third wears a plate on the fuselage side as ZK-RJE. (all three have clearly visible plates) Where did you get the cns from? One of the bits in the pile on the other side of the shed had 040 in red painted on it but I didn't see anything to confirm 011 or 015.

Continuing the blog from November 4th.
Evening Pete.
The three fuselages by my calculations, from left to right, and from my notes taken on the day (08-10-2008) have - on the left with the blue fuselage stripe is ZK-RJI which is plainly marked on the fuselage side. Carefully check the background of the third pic below. I did not see the cockpit plate in this aircraft. There is a plate on the outside, visible on the pic below, towards the left hand edge of the pic and below the hand hold. I don't recall what it had on it.
The middle fuselage I noted as Z37T 011, taken from a plate within the cockpit.
The third airframe noted from the cockpit plate as Z137T 040.
Checking against my notes on the NZ Civil Register I note that ZK-RJI is c/n 015.
The c/n 011 on the cockpit plate on the centre fuselage tells me that this airframe did not come onto the NZ register. However The previous identity of this aircraft was OK-RJE. The only ZK-RJE on our register to my knowledge was a Tecnam P2002-JF c/n 032; now in Australia as VH-IMP. (did you mispoll this as ZK-RJE ? or have I got it all wrong ?)
The right hand fuse c/n plate giving 040 makes it ZK-RZN (ex ZK-RDZ) as per the aircraft register and also the black fuselage stripes narrow this ID down. This also had red wing tips, rudder etc, but I noted no red bits at LX during my visit.
The wing centre section and elevators I did not take much interest in.
The three fuselages from another angle. "RJI" visible on the blue stripe on the far away fuselage.
Pete you say "the third wears a plate etc" Which one do you class as the third one ?
Interesting feedback thanks Pete. All the more reason to take good & copious notes. It just prooves that two people looking at the same thing, can come away with different observations.
Montenegro Airlines vs. Belgrade Airport
Montenegro is the most profitable market for Jat Airways while Serbia is most profitable for Montenegro Airlines. The national carrier of Montenegro was forced to end services from Belgrade to Zurich after the nation declared independence from the State Union of Serbia and Montenegro however operates many daily flights between Tivat, Podgorica and Belgrade. Montenegro Airlines currently pays fees at Belgrade Airport that are 90% lower than other international carriers and even Jat Airways.
