CONAR uses a cone of fabric fixed inside the apex hole with the vertex at the bottom and the circumference just above the apex hole. The air flows alongside the cone and exiting a narrow leak it is accelerated provoking a Venturi effect. After much testing the shape was optimized , as well as the dimensions and position of the cone and amazing results followed; using the same surface, a perfectly stable parachute had been created, with a 20% improvement in sink-rate but also a faster opening time because during deployment the apex hole is partially occluded by the cone. Tests from a hot air balloon showed, on average, a 10% faster opening time. The CONAR was tested after 150 m of free falling. (180 km per hour.)
