OZONE R&D department. Luc Armant interview ( 28-March 2018)

OZONE R&D department. Luc Armant interview ( 28-March 2018) 

Luc Armant was so kind to answer a few questions for all of us flying vultures :-) 

1- Dustoftheuniverse : What your personal insights on future paragliding designs? Will we experience some revolution projects? like the first BBHPP ? 

Luc Armant : Great stuff still to come. Yes !  some revolution should come. Future will tell…

2-DOTU: What can you tell the pilots of the future M6 replacement project? 

Luc Armant : Still experimental stage. Long term project. We want to create a new reference 3 liner wing.

2- DOTU: Will you be able to get more overall performance than the 6.9 aspect ratio M6 on a lower aspect ? and is it possible considering that the competition has lower aspect ratio close to 6.5 in the C class.

Luc Armant : Yes, it’s possible. Current prototypes have 6.5 aspect ratio with much more performance. 

3- DTOU: I personally Consider the Alpina 3 until this moment to have the best ratio of overall performance /comfort ever built on a C performance glider, what would your design philosophy toward the M7 project to be ? 

Luc Armant : I’m glad to read that. Delta3/Alpina 3 was a long and difficult project to get finished. Design philosophy for the M7 is simplicity, pleasure and high performance.

4- DOTU: What kind of handling the M7 would have ? Are you focusing also on handling ?  especially having a lower aspect ratio than the M6 ?

Luc Armant : Handling is very important. We currently have very pleasant prototypes in that matter. Lower AR helps as well.

5- DOTU: Will you consider one version? a 3 liner ? or two versions with one as two liner ?  

Luc Armant : Only one version.  

6- DOTU: Do you consider that the top speed is important for you to insert in the D category ?

Luc Armant : Yes. But it needs to stay reasonable in term of safety after collapses at full speed. It can’t be as fast as current CCC.

7- DOTU: Any release in 2018 ? 

Luc Armant : Yes.

8- DOTU: Is there any new materials ,as lines, cloth, that can increase future safety and performance ?

Luc Armant : No. Light material and light construction helps a bit safety. It’s more new design feature and setting that can help a lot.

9-  DOTU: what category do you forecast that will get the most benefits in performance in the near future?

Luc Armant : D category remains the most interesting for evolution specially since the others have been banned of collapse lines, but this may be revised in a near future. Many are now realizing the downside of this ban.

DOTU: Thank you very much Luc for your answers. Looking forward.

Swing Nyos RS 
The last Swing glider i flew with the RAST system was the Arcus RS, and here’s the new high-end B from the same manufacturer, the Nyos RS in size S (75-95) flown at 93.5 all up with an X-rated 6 harness.
The Nyos RS construction holds a normal nose. The lower lines are sheathed with the higher ones unsheathed. The lines are slightly thicker than the competitors in the B category.   
Launching is quite easy in nil wind, and even in strong breeze. The Nyos inflates quite smoothly and evenly.
First turn, i could feel the moderate to short response on the brakes, with quite a nice agility in thermals ! The Nyos RS turns quite flat with moderate pressure on the brakes and could be described as quite agile! It doesn’t handle like an acro wing for sure and it’s not suppose to, but for a handling seeker like me, it’s very satisfying ! Thermals can be cored very tight, even the turbulent ones. 
The handling alone doesn’t really matter sometimes if the glider above the pilot is jumping around all the time. Underneath the Nyos RS, the movements in turbulent air can be described as “computerized self controlled” , as the Nyos RS feels very compact and super smooth to fly !
I flew this glider in some turbulent air, and got myself into a sunny lee side of a cliff, when the wind was blowing around 20 km/h from the other side. Usually the experience is not really joyful…but it was quite soft on the Nyos RS ! I got a bullet thermal that got me into higher layer, and kept my flight going on further.
I have been flying this path for a very long time, and underneath plenty of gliders. The Nyos RS was the coolest, most reassuring, comfortable glider ever to be flown among B’s ! 
The experience flying the Nyos RS is exceptional when it comes to comfort ! Even compared to some low B’s !
 Having said that, the Nyos RS could not be considered as a dull glider at all. 
It will inform the pilot about all the movement of the air around, but with such rare serenity and homogeneity and an efficient leading edge that surfs the airmass moving constantly forward in a super smooth way ! Incredible ! All that, led me to say, that the Nyos RS is indeed “The Rolls Royce of the sky”  ! 
Even in turbulent air, there not pitch back ! The Nyos RS just simply move forward quietly with that amazing solidity and super cohesive structure ! Some B gliders will have sharp movements, or a bit of yaw, some pitch…But not the Nyos RS. It just inform the pilot and filters wisely only the excess of turbulence !
Gliding with top high B gliders in moving air, i could notice that the Nyos RS is very competitive, and i could put the gliding efficiency among today’s top four, high-end B gliders.  
The interesting part of the glide in turbulent shaky air, was the easiness of the C risers control.  Using the bar in total confidence with the C riser control will deliver a quite efficient glide and they are super easy to use with moderate and progressive pressure. If only a thinner line version would be feasible, it could perhaps squeeze up even more overall performance to dominate the category.  
Climbing in weak and strong could place also the Nyos RS among the top 5 gliders in the high B category.  
Ears are stable, efficient, and reopen without pilot input. 
The pluses:  The ratio of usability ! I mean exceptional comfort and homogeneity with smooth information coming through! 

Conclusion: The Nyos has a normal nose, normal width lines, yet it glides beautifully and efficiently into wind. As for the flight characteristics and compact structure, I can totally confirm that the Nyos RS has somehow a different feel from many B’s i have tested. It has a very taught, super homogenous structure, with precise and direct brake response.  The comfort flying the Nyos RS is very high. Pilots flying in strong air and alpine conditions wishing for a solid, well mannered companion, should strongly consider flying the Nyos RS as a good option.  
I’m not an engineer to talk about RAST and the benefits that comes along…but it seems what i have experienced flying the Nyos RS couldn’t be understood otherwise. 

This is only my opinion. Make your own !

NOVA Sector S

NOVA Sector S 
After 10 years, NOVA finally released their new C replacement. A flat aspect ratio of 6.0, unsheathed lines all over and  a 3 line configuration setting. 
The factor 2 is made with light fabric and the S size weights around 4 kg.

Launching the light cloth Sector is easy in all conditions. Those light gliders can launch even without touching the A's ! 

I flew the Sector S at 95, 96 all up. This load enabled the Sector to be quite taught and efficient in all conditions.
IMHO, Its better to put the exact pressure in a car wheel in order to take corners at high speed. Any less pressure in those wheel won’t give you optimum efficiency. It’s the same with gliders they will perform much better (when they reached their optimum shape design) by loading them precisely. I think 95 is a good balance under the Sector S size. 
Of course the Sector S can be flown at mid-weight, but will loose it’s inside pressure flying it in turbulent air, as all other gliders do in it’s category.  

The brakes have medium pressure  until 15 cm of pull then they are slightly heavier. The Sector S at my loads need 2 (two) centimeter of pull, to turn it !  The Sector is an agile glider that doesn’t dive in turns even when lowering the brakes while circling. It tries sometimes to get out of the turn if the brakes are released, and some weight shift would be also quite beneficial in tight small cores.  

I flew next to a Delta 3 MS and Alpina 3 S in order to know the overall performance of the Sector S. In weak thermals, ( less than 0.5 m/s) the Delta 3 MS and the Sector S are very close in climbing ability. 
You can look at the C comparison as it has been updated with the latest C wings for small details if you wish…

In well built thermals, I mean over 2 m/s, the Sector jumps upward like a powerful but well mannered horse ! It really climbs very fast ! I think it has one of the best climbing ability in those thermals like a high end C ! It doesn’t pitch back, it does very slightly pull you into the thermal with power ! I personally like that behavior ! Some pilots would like the calm surge behavior of the Alpina 3, some would like the ones on the sigma 10 or the slightly sharper one on the Sector S. 

In turbulent thermals, i found that the Sector behave like a small energetic kid. The risers are more nervous than the S10 in translating the airmass. Don’t understand me wrong, the Sector quality of telling you what’s going around is quite nice for sensible pilots. The informations of the air are transmitted mainly by the risers. I was finding the Delta 3 to be quite tame to my personal taste in feel under the glider. Some pilots over-heree loved the Delta 3 soft feel ! It’s about taste…The Sector is more informative. 

NOVA did mention that the Sector S is between the Mentor 5 and the Triton 2. I think it’s quite accurate, but i have to add, with a slight shift toward the Triton 2 S in feel underneath the Sector 2 which i think shares its DNA.  If you think that the Mentor 5 is quite lazy to your taste, you will find an interesting feel with some tasteful but quite manageable spices under the Sector 2. 
This has been said, i have to add also that the Sector 2 remains in the middle of the C class in terms of piloting level. It’s an easy C for a pilot who already has two full seasons on a hot B. 

Gliding properties:
For an aspect ratio of 6, the Sector S glide angle angle is similar to the Delta 3 MS at trim and especially at full bar, with 1 km/h faster on the Sector S if both gliders are similarly loaded. Trim speed is similar. 
Gliding in turbulent air, is as efficient on the Delta 3 as it is on the Sector S !  
The Sector S ridge racing and gliding in thermo-dynamics is quite efficient ! 

Big ears have moderate stability and reopen without pilot input on the S at 96 all up. 

Conclusion: The trailing edge look quite weird and wavy…but it could be a design for efficiency… The Sector S is an informative wing that shows you what the air is doing, but middle C glider in terms of piloting level. 
The strong point is the climb in good thermals, that showed me an impressive search toward the lift. A very good glide angle for the C category, at trim and especially at full bar, fast enough, handles well. 
A strong contender in the C category for sport class competitions, and interesting XC potential for sure !
This is only my opinion. Make your own !

Faster at second bar ( if equally loaded ) : 

1- Queen M = Advance Sigma 10, 25 = Mac Para Elan 2, 26 and 24 =Queen 2 MS = Sector S

2- Ozone Delta 3 ML = Artic 3 Race

5- Volt 2 SM = Trango XC2 = BGD Tala = Carrera = Elan = Supair Taska S 

Big ears efficiency: 

- Ozone Alpina 3 MS and S : ( stable, efficient, reopen on input)

- 777 Queen 2 MS : moderate stability, they usually flap, shake a bit sometimes, but reopen quickly

- Nova Sector S (stable, efficient ,reopen without intervention )

- Up Trango XC 3 ( stable and ok for a 7:0 aspect ratio glider! ) 

- Cayenne 5 XS ( small -2m/s and stable, little big and un-stable on this size ) 

-Advance Sigma 10 ,25 (with outer A’s little stable, flap a bit, efficient with bar, reopen with a slight brake pull ) With outer B’s (stable efficient with bar, reopen quickly) 

- Cure M (stable ears, efficient)

- Lynx M ( Stable, efficient)

Artic 3 = Artic 3 Race = U-Turn Passion SM =Triton 2 S (stable moderate ears ) =UP Trango XC 2 S/M= AD Volt SM = Aspen 5 26 . 

- Marvel 25 (moderate use of big ears-moves a bit)

- BGD Lynx M ( Stable ears ) reopen by themselves.

The Triton 2 S requires much more energy from the pilot to control it in heavy conditions. 

The Lotus one has also some impressive performance, but to place it wherever you want in turbulent conditions requires also some finer inputs. 

The Aspen 5 is really some great glider at second bar! It resembles the Triton 2 S in full speed glide! …To extract the full performance it needs an active piloting for sure and the way to turn it quickly in turbulent cores needs a little time. 

The Cayenne 5 has the edge in surges into thermals, and the superb sharp and direct brake travel! 

In weak conditions, it requires a bit more to handle than the Alpina 2 but it’s a very efficient C glider. If only the ears were a bit more efficient and stable … 

The Trango XC 3 is demanding to fly regarding the surrounding C’s. Of course it’s very efficient in cutting and climbing. The glide is good also but it needs the most energy to handle in this specific category! 

The BGD Cure surprises by the ratio comfort/aspect ratio. The overall package of performance, accessibility and pleasurable feel is very nice. 

The AD Volt 2 SM is a very comfortable glider to fly with a very nice brake authority. The Climb rate is ‘great ! 

The Elan 2 26 is an easy C glider, fast trim, nice glide.

The Elan 2 24 is more demanding to fly than the size 26. 

UPDATE for usability: 

Please remember that sizes differ a lot and surely the loading's! Other sizes may have other characteristics … 

The first 4 places are very close. Indeed superb machines! Different taste for everyone … 

The most important: Only the pilot will make a difference. 

C & D gliders: UPDATED. 

This grade is to say how busy a glider is, in strong conditions, or the one that’s more difficult to manage, comparing to the B category. 

Since this is a very delicate comparison, i must point out that the glider that has quicker authority on the brakes like the Triton 2 will enable a good pilot to keep it swiftly overhead. Some doesn’t have that quick response and in strong conditions they won’t keep the pilot as busy, but he will be the ‘passenger’ for a short lapse of time … 

The grade doesn’t indicate the one that recovers easier or harder!!Only that keeps you busier! Most will have easier recovery than the higher graded!
