Case Study
“Ansys Fluent® software, with its simple GUI and powerful visualization capabilities, is a guidepost in our aerodynamic design. For our team, it was challenging to perform the wind tunnel testing of a rocket flying at 400 km/s. However, using Ansys Fluent simulation software to visually understand the pressure distribution and interference with the airflow allowed us to select an appropriate design without hesitation.”
— Haruki Iwata, Rocket Group PM, Nagoya University, NAFT
When designing a rocket, one of the key considerations that researchers face is accurately predicting its drop location. Getting this correct is imperative to ensuring safety, preventing potential damage, and avoiding the loss of the rocket itself — which harms data recovery rates. Solving this problem is a top priority for Nagoya University Aerospace and Flight Technologies (NAFT), a team at Nagoya University in Japan that uses their unique free-form fin rocket designs to participate in joint launch experiments hosted by hybrid rocket organizations.
NAFT had to overcome three key challenges to succeed in their goals. First, the rocket they are developing has dynamic free-form wings, which require complex flow field analysis. Second, they were tasked with minimizing drag in their fin geometries. Third, the team’s analyses required them to study many different conditions depending on the attitude of the aircraft in flight.
A contour plot created by Ansys Fluent software that shows helicity and enables researchers to see where vortices are and how they are generated.
NAFT used Ansys software to obtain aerodynamic parameters during flight and analyze a variety of conditions, including different fin shapes, airspeeds, and attitudes (i.e., the pitch or roll angle.) Simulation, and the abundant visualization features provided by Ansys software, enabled the team to:
