Vorticity was the prime contractor for this ESA study which aims at an improved understanding of parachutes operating in the subsonic regime. In order to achieve the programme objectives, a number of potentially suitable parachute types were selected, and an extensive range of tests were performed. Previous missions, existing parachute […]
Vorticity produced three different Earth Return Capsule designs. Two were based on a 45° sphere-cone design similar to the JAXA Hayabusa and the NASA Deep Space 2 probes. The third was a 60° sphere-cone design based on the Huygens probe. All three variants were designed to self-align in the correct […]
Vorticity designed a number of small (170 mm to 340 mm) Disk-Gap-Band parachutes which were scaled from the parachutes used successfully on the Huygens lander. These were tested in the NRC 1.5 m Trisonic Wind Tunnel in Ottawa, Canada. The parachutes were tested at Mach numbers between 1.6 and 2.25 […]
The Parachute Engineering Tool is a software toolbox which provides modules to perform all the common parachute engineering tasks throughout the design process of a space mission (or indeed any system utilising parachutes). All the modules are integrated within a Graphical User Interface which allows them to be run individually […]
The SUPERMAX mission (Supersonic Parachute Experiment Ride on a MAXUS rocket) was flown successfully on the MAXUS 9 flight which took place on 7th April 2017. A 13.7 kg test vehicle with a diameter of 290 mm was designed to replace the ballast mass which was flown on previous MAXUS […]
For the Airbag design activity, Vorticity in partnership with TNO-CGG Technologies, Airborne Systems and the University of Leeds, has performed a number of tasks leading to a design and development plan for an airbag system capable of meeting the requirements of the mission. Initial tasks focused on developing and refining […]
Probes of the shapes used for all Mars missions are dynamically unstable at low supersonic and transonic speeds, exhibiting increasing pitch oscillation amplitudes.
Ensuring a successful parachute system is a vital element of the design of the ExoMars 2016 mission. Vorticity has responsibility for the parachute system performance, oversight of parachute system design and system level testing.
Descent and landing are two of the most challenging aspects of placing a probe on the Martian surface. Vorticity primed this study of the design and analysis of descent and landing systems for an ExoMars class lander including parachutes, retro rockets, lateral velocity control rockets and vented airbag system.
