After winning the bid for the
acoustic treatment project of the AAWT Aeroacoustic Wind Tunnel at China
Automotive Engineering Research Institute (CAERI) in Chongqing in 2016, Landtop
Technology secured the infrastructure project of the wind tunnel laboratory at
China Automotive Technology and Research Center (CATARC) in Tianjin in 2017,
and was awarded the aerodynamic aeroacoustic wind tunnel project of GAC R&D
Center in 2019 — the world’s only full-scale vehicle aeroacoustic wind tunnel
equipped with high-temperature environmental testing capability.
Landtop maintains a leading bid-winning rate for acoustic treatment and acoustic measurement work among domestic aeroacoustic wind tunnel projects. Laboratories constructed by us, including Tongji University Wind Tunnel Center, CAERI Chongqing Wind Tunnel, CATARC Tianjin Wind Tunnel and GAC R&D Center Aeroacoustic Wind Tunnel, have all been put into official operation.

The first automotive wind
tunnel in central and western China has been put into operation in Chongqing.
