NEW Ozone Delta 4 – EN C now available in 2020 😉

Produktinfo

Ein Quantensprung

Durch die Spitzenleistung in seiner Klasse und das einfache, angenehme Handling wurde die Delta Serie lange Zeit als Referenz in der Kategorie EN C herangezogen. Der Delta 4 führt dieses Vermächtnis fort,  und zeigt dabei den größten bislang dagewesenen Leistungszuwachs, während er auch mit Sicherheit, Komfort und einfacher Handhabung überzeugt, wie man es von einem Delta gewohnt ist. Diese Komponenten haben ihn schließlich so bekannt und beliebt gemacht.

Der Delta 4 wurde mit einem neuen Leinenlayout konzipiert: ein klassisches 3-Leinen Design unterstützt den mittleren Bereich, wobei zwei Leinen an die Flügelenden laufen. Das verringert nicht nur beträchtlich den Widerstand, sondern verbessert auch die spannweitige Auftriebsverteilung, und das besonders im beschleunigten Flug. Auch das neue Profil, das wir vom M7 weiterentwickelt haben, trägt mit seinen kleineren Öffnungen und den Ozone G-Strings ebenfalls zu einem Leistungsgewinn bei. Der Delta 4 ist eine effiziente „XC-Waffe“, die in seiner Klasse absolute Spitzenleistung hinlegt, ohne dabei Kompromisse in Sachen Sicherheit einzugehen.

 

Leistungstest

Der Delta 4 zeigt einen massiven Vorteil in der Sinkgeschwindigkeit gegenüber dem Delta 3, und zwar +12cm/s. In ruhiger Luft sorgt das jede Minute für mehr Höhe. Bei turbulenter Luft ist der Leistungsgewinn noch größer, da der Delta 4 sich durch Turbulenzen schneidet, und dabei Windböen nutzt um Höhe zu generieren, ähnlich wie ein Wettkampfschirm. Im beschleunigten Flug ist die Maximalgeschwindigkeit des Delta 4 um 3 k/h höher als die des Delta 3.

 

Wahre Leistung

Dank des neuen Profils und der optimierten Innenstruktur konnten wir die Solidität im beschleunigten Flug erheblich verbessern. Auch die intuitive und effiziente Kontrolle des Anstellwinkels macht den Delta 4 zu einer Gleitmaschine. Die Struktur des Delta 4 ist unglaublich stark und stabil, und das Profil bleibt sogar in aggressiven Turbulenzen unbeeinträchtigt, behält seine Form und Effizienz bei, und leidet nicht unter einem Leistungsverlust durch Deformationen an den Flügelenden.

 

Neues ACR System

Über die neuen Ozone Kontroll-Tragegurte (Active Control Risers), die wir von der Mantra Serie übernommen haben, ist der Pilot mit seinem Flügel verbunden, und kann intuitiv agieren. Diese innovativen Tragegurte geben dem Piloten die volle Kontrolle über den Anstellwinkel des Schirmes. Und das über den gesamten Geschwindigkeitsbereich hinweg, ohne dabei die Krümmung des Profils zu deformieren. Sie wirken sowohl auf die B- als auch auf die C-Leinen, und bieten das Kontrollniveau eines 2-Leiners mit den Annehmlichkeiten eines 3-Leiners.

 

Sicherheit

Der Delta 4 ist superbrav, und der bislang artigste seiner Serie. Der Schirm ist von Natur aus kaum anfällig für Einklapper, und das sogar bei voller Geschwindigkeit und in starken Turbulenzen. Das Verhalten des Delta 4 nach einem Einklapper ist das sanfteste seiner Serie. Ausgiebige Tests haben nur eine geringe Tendenz zum Überschießen oder zu Rotationen nach einem Seitenklapper und keine schockartige Wieder-Öffnung gezeigt. Sein Verhalten bei Frontklappern ist ausgezeichnet: der Schirm öffnet sich sofort wieder.

Dank des SharkNose Profils, der geringen Streckung, einer verbesserten Struktur und Leinenarchitektur ist der Schirm sowohl gegen Spinn als auch Stall sehr resistent, und kann auch bei sehr geringen Geschwindigkeiten sicher geflogen werden. Das macht Toplandungen oder Landungen in engen Bereichen relativ einfach – und das bei einem derart hohen Leistungsniveau.

 

Auf Flugvergnügen getunt

Verglichen mit dem Delta 3 hat sich das Handling beim Delta 4 enorm verbessert. Die Bremsen sind linear – präzise im ersten Teil des Bremsbereichs, und effektiv im zweiten – das macht es einfach, den Querneigungswinkel anzugleichen, und den Schirm exakt dort zu platzieren, wo du ihn haben möchtest: im Herz der Thermik. Die Steigeffizienz wird von der starken Flügelstruktur und der ausgezeichneten Segelkohäsion unterstützt. Der Schirm hält sogar in turbulenter Thermik einen ausgezeichneten Level an Roll- und Nickverhalten, und vermittelt ein agiles, freudvolles Gefühl.

 

Der Pilot

Der Delta 4 ist für Intermediate und fortgeschrittene Piloten bestens geeignet, die zwischen 50-100 Stunden im Jahr fliegen und SIV Erfahrung haben. Die einfache Handhabung und sein hohes Maß an passiver Sicherheit machen ihn auch für Piloten zugänglich, die von einem EN B Schirm wechseln wollen, der an der oberen Klassenleistung angesiedelt ist. Die Leistung und das pure Flugvergnügen machen den Delta 4 für Piloten mit mehr Erfahrung, die mit einer höheren Sicherheitsmarsche fliegen wollen, zum perfekten Schirm: eine XC-Maschine mit klassenbester Leistung, die einfach Spaß macht.

SHARE YOUR DESIGN

ABOUT CUSTOM COLOURS

Ozone encourages you to customize your own personal colour combination for your wing. Customization generally incurs a fee. Once you’ve decided you can share your design with your friends, or if you are ready to order, send it to your local Ozone dealer to verify the charge and place the final order.

Please note that because the glider will be built specifically for you in the Ozone factory, payment must be received before production can begin.

FABRIC COLOURS AND UV RESISTANCE

Please be aware that the colour you see on your screen may not accurately represent the actual fabric colour. Secondly, different cloths specifications with the same color name may vary slightly, please see here for an example. Given the wide varience in monitor calibration and the fabric appearance in different light and colour combinations, it is impossible to perfectly represent fabric colour on screen. If you have any doubts about the colours, look at photos of various wings on our website to see them in different light and colour combinations or contact your local dealer to see the fabric in person.

All of the fabric that we use undergoes extensive testing in prototype colour phase to ensure colourfastness, mechanical stability, porosity, and general longevity before we put it into production. Once our fabric is in production, every meter of it is rigorously inspected upon arrival in our factory, and fabric which does not pass our stringent quality control standards is returned to the manufacturer. We are frequently asked, „Which colours last the longest, or have the best UV resistance?“ All of the colours that we stock score between 4 and 5 on a scale of 1-5, with 5 being the highest possible rating for longevity.

Ozone Delta 4 MS & ML

OZONE Delta 4 ML and MS
And here’s the new EN-C from Ozone.I had two Delta 4 for testing. An ML that I flew at 101, with lots of ballast, and two pizzas, the MS size at 92 all up with just one ‘croissant’;-).

Launching the ML and MS at their respective weights is pretty direct. Probably it rises slightly less than the D3, but nothing worth mentioning. No hardpoints, no surge, just an easy to launch C.

Usually, I fly smaller sizes, and when I fly the bigger ones or the Medium ones, I feel that they are too dampened compared to their little sisters…In-flight on the ML size, on a strong and turbulent day, my flying buddies were all over the place with hands going down and up, and wings getting tossed around, and I thought I was just sitting alone among that chaos, sipping a cup of tea!Really…the Delta 4 in ML size at 101- 102 is super comfy to my taste! Not boring at all but solid, smooth, and super homogenous.
The gliders that were around, were the Cure 2 M (75-95), the Flow Fusion M (85-105), and later the LM7, MS (75-95), and some other B’s. They seem to be doing some sports workout!
Anyway, the brake authority on that ML size at my loads are super nice! I was amazed that this ML size would turn quite nicely! Used to feel that bigger sizes feel like bigger ships to turn, but no, that Delta 4 ML has a very nice coordinated and smooth turn, with very good agility. The climb rate is really impressive on the ML!After many times, I felt that I had an edge over all the mentioned gliders in the air!In weak, and especially in sudden thermals. The D4 shoots upward quickly.

Doing some glides with the Cure 2 M, at trim, showed me after many attempts that theD4 ML has an edge at trim and a large edge at full bar!Gliding next to the Fusion Mshowed that the Fusion had a slightly faster trim speed, but when matching the Fusion trim speed, again, I felt that I had an edge at trim, and a large one at full bar!

So it was preferable to see that ML size with the LM7 MS.My friend flying the MS is a good pilot, and we glided over 10 KM, three times, with him pushing the bar all the time. On the Delta 4 ML, I could always be on his wingtip, with a slight edge for the Delta 4 ML in lifts!

It was very impressive to see that easy to flyD4 ML (6) aspect ratio, EN-C,at full bar has nearly or similar glide angle as the LM7 size MS!Many climbs and glides were made with the same results. I know the LM7 was a size smaller than the D4 ML. It was only to give an idea about the overall performance.
Ears are stable a bit if you don’t pull much. They lock if you pull them once slightly. Just like the Mantra 7 ones. Not really super-efficient, but ok.
Three days later, I received the Delta 4 MS size (75-95).

Launching the Delta 4 MS, at 93 all up in very dry and turbulent air, showed me that there is a large difference in roll feedback with the bigger size. I couldn’t get a cup of tea, but able to talk on the phone ? . The roll movements are more present than the ML size, the pitch movement is still very stable.
My friend on his Cure 2 M commented that the air was super rowdy and barely acceptable. The D4 MS was quite manageable with a high degree of comfort.The structure is very homogenous and solid, especially(if it is well loaded! ) 93 all up was ok.
The handling and brake authority are much better to my liking now. The Delta 4 MS at 93 is an agile glider.I could place it in that turbulent air exactly where I wanted after getting hammered with some instant powerful thermals that lasts two seconds…Getting through and inside those nasty narrow lifts was possible on the D4 MS.
Now comparing with the same sizes as the D4 MS ( 75-95).
Climbing next to my friend on his Cure 2 M (75-95), with the same loadings as mine now, showed me that in strong air and powerful thermals, the D4 climbs upward again, quite rapidly! At the end of that day, when thermals were very weak, they both could float next to each other, and it was super difficult to tell if either climbs better or float better. Anyway, my C comparison will be updated for those tiny details if needed.

Doing some long glides next to the same Cure 2 M, (they have the same trim speed), showed me now that the D4 MS size has a slight edge in glide at trim and the difference is smaller than I got on the ML size.
For instance, the difference at trim after a 5 km run is only around 5 m difference for the Delta 4 MS, but when we applied full bar, the difference became bigger for the Delta 4.
The D4, MS has a good edge and an impressive glide angle at full speed.Now at full speed for both, and overlapping the pulleys on the D4, I was getting slightly faster top speed. Probably around +1 km/h…
Comparing the M7 size MS to the Delta 4 size MS is really interesting. The gap is super small! Like perhaps the edge for the M7 is found when low facing the sea breeze and getting those tricky thermals, the M7 will have a slight edge in surfing through the airmass. Saying that the Delta 4 in that particular difficult place with shine flawlessly among C’s. It cuts through like the M7 but slightly slower and tamer. It will take its time to dig through calmly. Ozone has strongly narrowed the gap between the Rush5, Delta 4, Mantra7!
Racing the Delta 4 at full speed in turbulent air, and steering with the C risers is quite efficient, as I was able to clear most of the pitch and roll by the smooth and easy to steer C risers.Like I said, with that easiness in flight, and performance at speed, the Delta 4 will give the pilots a clear edge in sports competitions. The C riser controls have a moderate pressure and linear response, with very good authority on the profile.
Ears‘ behavior is similar to the ML size. If you pull a lot, they will try to re-open,A little pull will get them stuck and stable, with a moderate decent rate. Wing overs are a delight! Get quickly upside down!
Conclusion:
I was super lucky after the corona lockdown to test fly some amazing gliders.
I also have to add that the Delta 4 MS has a more subtle feel, and a little bit more communicative than the Delta 3 MS in showing and sensing a little bit more the airmass. That characteristic is enhanced over the D3 and it’s a good move from the R&D department.
For the C category, what impresses me the most is when a manufacturer works on a moderate aspect ratio glider, like 6.05 for the Delta 4 and achieves an impressively complete package of feel-able passive safety, high comfort in turbulence, superb agility, with a pleasurable feel,top-end gliding performance and fast enough for the C category!
I’ll keep those new gliders coming through to see what could be more possible, and will keep one Delta 4 MS size as the new C reference.
Comparing the same sizes:Mantra 7 MSVSDelta 4 MS, will give a tiny edge for overall performance to the M7, but I think Mantra 7 pilots must watch out carefully, Delta 4 pilots on full bar !! 😉
