“…In order to validate computer codes for predicting the performance of the new types of decelerators that are needed for future missions to Mars, Schairer et al [16] conducted simultaneous, synchronized, high-frequency measurements of both unsteady flow in the wake of a tension-cone decelerator in the subsonic flow and unsteady shape of the decelerator. Sengupta et al [17] measured the spatially and temporally resolved velocity field upstream of the Orion drogue parachute model with PIV, and studied canopy dynamics with high speed video, and time resolved canopy and capsule forces with a force balance and 3-axis load cell. Han et al [18] established multi-node models to calculate the shape of full-filled cross parachutes and found that the axial force coefficient increased with the increase of parachute suspension ratio and arm length ratio.…”

In the present study, an experimental study was conducted to characterize the effect of Reynolds number on flow structures in the turbulent wake of a circular parachute canopy by utilizing stereoscopic particle image velocimetry (Stereo-PIV) technique. The parachute model tested in the present study was attached by 28 nylon suspension lines and placed horizontally at the test section center of the wind tunnel. The obtained results showed that with the increase of Reynolds number, the intensities of the vortices near the downstream region of the canopy skirt were found to increase accordingly. However, the increase of Reynolds number did not result in a significant change in ensembleaveraged normalized x-component of the velocity, ensembleaveraged normalized vorticity, normalized Reynolds stress, and normalized turbulent kinetic energy distributions in the turbulent wake of the circular parachute canopy. The obtained results are very useful to further our understanding about the unsteady aerodynamics in the wake of flexible circular parachute canopies and to constitute a reference for CFD computation.

“…A time-dependent and locally varying model for the geometric porosity which accounts for the instantaneous flow state is introduced. Sengupta et al 5 performed wind tunnel tests to quantify the reduction in drag of the MPCV's drogue parachutes due to the presence of the MPCV itself. These tests included 3-force sting measurements and particle image velocimetry (PIV) analysis.…”

Simulations of a 10% scale Multi-Purpose Crew Vehicle and its drogue parachute were carried out using US3D, a finite-volume computational fluid dynamics code, with capsule angles of attack at 0, 30 and 50 degrees. A model for the geometric porosity of the parachute is incorporated which locally varies the mass flux through the surface based on the instantaneous flowfield. These simulations were then compared to wind tunnel tests, including mean drag measurements and particle image velocimetry data. It was found that the simulations matched the wind tunnel drag within 4% for α = 0 and 30 • with the maximum drag deficit due to the capsule being 13.4% at α = 0 • . Pressure data from the simulations was used to deform a structural model of the parachute to the correct inflated shape, as a precursor to future fluid structural interaction work.

“…The drogue installed at the tail of the seismic array can provide backward drag resistance, which can effectively reduce the swing of the seismic array. Sengupta et al [3] examined the performance of a conical ribbon drogue parachute in the wake of a subscale Orion command module. The drogue can provide command module stabilisation and deceleration prior to the main parachute deploy.…”

A drogue is used to stabilise and straighten seismic arrays so that seismic waves can be well-received. To embed the effect of a cone-shaped drogue into the numerical modelling of the deep-towed seismic survey system, one surrogate model that maps the relationship between the hydrodynamic characteristics of the drogue and towing conditions was obtained based on data-driven simulations. The sample data were obtained by co-simulation of the commercial software RecurDyn and Particleworks, and the modelling parameters were verified by physical experiments. According to the Morison formula, the rotational angle, angular velocity, angular acceleration, towing speed, and towing acceleration of the drogue were selected as the design variables and drag forces and aligning torque were selected as the research objectives. The sample data of more than 8500 sets were obtained from virtual manoeuvres. Subsequently, both polynomial and neural network regression algorithms were used to study these data. Finally, analysis results show that the surrogate model obtained by machine learning has good performance in predicting research objectives. The results also reveal that the neural network regression algorithm is superior to the polynomial regression algorithm, its largest error of mean square is less than 0.8 (N2/N2 mm2), and its R-squared is close to 1.
