CASE STUDY | SHOTOVER F1 Camera Turret Analysis
SHOTOVER create high performance vehicle mounted camera systems utilised in blockbuster motion pictures as well as documentaries, high-profile sporting events, broadcast television, and advertising.
- With a demand for use of the F1 camera turret on higher-speed aircraft, SHOTOVER approached Caliber Design to carry out a computational fluid dynamics (CFD) analysis to determine the maximum aircraft velocity for the unit.
- Full scale destructive tests on aircraft would be expensive and potentially dangerous.
- Caliber were asked to determine the drag loads on the three-axis turret assembly in a variety of configurations, then compare these results with physical test data to provide operating curves and, combined with momentum calculations, a never-exceed velocity (Vne) for the unit.
- In an effort to reduce cost for the client, Caliber used OpenFOAM, a linux based open-source CFD platform.
- With complex flow characteristics at air speeds of up to Mach 0.8, a specialised solver was deployed and, due to large solution times, solutions were run in parallel across four different computers, for days at a time.
- With a large amount of generated data, Caliber were able to provide a concise summary of the results for the SHOTOVER team to use in their next stage of testing.
- With the data provided by Caliber, the SHOTOVER team was able to determine an operating window and a never exceed velocity for the camera turret without the need for expensive and potentially dangerous full scale destruction tests.
- Caliber provided pressure loads on the lens cover to provide an input for physical testing.
- The SHOTOVER team has a better understanding of the behaviour of the camera turret under high air speeds, which will prove invaluable for future designs.
- With expensive sub-componentry, carrying out CFD enabled the client to make significant savings.
- CFD also prevented the need for failure testing on an aircraft – a costly and potentially dangerous task.
- Caliber consulted throughout the project with the client and ensured that they were happy with the final result.
- The SHOTOVER F1 Gyro-Stablized Camera Platform was successfully launched at Hei Heli-Expo in February 2016.
We were impressed with the team at Caliber Design. We had a tight time frame. They quickly grasped what we needed and then set out to achieve that, giving us clear and concise results.Brad Hurndell
