Ozone Delta 5

The Delta 5 - A Quantum Leap

The all-new 2-liner Delta 5 is still perfectly placed in the C segment as its predecessors. It is the straight replacement of the successful Delta 4, keeping the ease of use, comfort of an accessible EN C, and adding the performance of a 2 liner. With 65 cells and an Aspect Ratio of 6.07, the canopy is built with Dominico 30D. It is currently under certification in size ML. Sizes will be launched as soon as certified.

• 2-Liner technology in the wingtips significantly reduces drag while improving spanwise lift distribution.
•  
• A new lower-drag profile developed from the Mantra series with smaller openings and higher efficiency.

Performance Testing

The D4 has a massive +12cm/s sink rate advantage over the D3 during full speed glides. In calm air, this results in a full glider-cone height gain every minute. In turbulence, the gain is larger as the D4 cuts through turbulence using gusts for altitude gain, much like a competition wing. The max speed of the D4 is 3kph faster, walking away from the D3 in accelerated flight.

True Performance

Intuitive and efficient AoA control, an improved airfoil design, and optimised internal structure make the D4 an XC glide machine in turbulence. Its structure is the strongest we have yet made. Even in aggressive turbulence, the profile remains undisturbed, retaining its shape and efficiency without performance loss from chordwise deformation.

New ACR System

The new Ozone Active Control Risers, inherited from the Mantra series, allows full AoA control throughout the speed range without deforming the camber of the profile. The ACR system acts on B & C lines giving 2-liner control with the comfort of a 3-liner design.

Safety
This is the best behaved Delta yet. The D4 is highly resistant to collapse, even at full speed in turbulence. The post-collapse behaviour is the mildest of the entire Delta series. This has been achieved by keeping the aspect ratio relatively low, by improving the structure and line architecture, and by optimising wing twist. Extensive testing shows little tendency to shoot or rotate after side collapse, and no shock re-inflation. The behaviour in frontals is excellent with the immediate reopening.

Thanks to the Ozone Shark Nose profile, the wing is resistant to spin & stall and can be flown safely at low speed making top landings, or landings in tight spots, simple for a wing of this class.

Time well spent

Luc Armand, Ozone chief designer says

"The work on this project took a long time, with 20 different prototypes and a multitude of platforms in terms of number of cells and line architectures.

The Delta is the most important glider in my heart, ever since the Delta 2, which was an achievement for me as a designer, particularly in terms of what it brought to the industry in terms of handling in thermals and solidity and comfort in turbulence.

The Delta is a very versatile model for cross-country flying in all conditions, and I know that each new model is eagerly awaited by the community.

For this glider, the challenge was very high as it was imperative not to lose any of the handling and ease of the Delta 4 while improving inflation, performance, solidity and control at high speed.

I'm particularly happy with the pleasure the glider gives me in thermals, linked to the great precision at the start of braking but also during re-coring thermals. This was a real challenge for a short two-line structure built from durable and robust materials. I defy anyone to recognize ‘blindly’ that this is a 2-liner, even during inflation.
