Maintaining human thermal comfort in cold indoor environments is crucial but usually involves excessive energy consumption and massive greenhouse gas emissions. Thermoregulating the human body by using advanced clothing is emerging as a promising solution to effectively and energy-efficiently achieve personal thermal management. An air inflatable suit(AirST)using a series of air chambers as the thermal insert was developed for the purpose of adjusting clothing thermal insulation and hence improving personal thermal comfort. The thermal insulation regulating performance of AirST was investigated through thermal manikin tests and wear trials. Compared with the AirST without air inflation, AirST after inflation with air had a desired effect, which could not only increase local clothing thermal insulation by a range from 4.5% to 24.8% but also alleviate cold strain and provide significantly higher local skin temperatures, mean skin temperature and mean body temperature. After inflation, AirST successfully improved the whole-, upper-and lower-body thermal sensations in a cool environment. The acceptable heating setpoint temperature by the air conditioner could be decreased while using AirST with inflation, which saved approximately 30% of building energy consumption. As the AirST without air inflation can also be worn as regular windproof clothing, this versatility saved approximately 12 kg CO_(2)e emissions in the production process.

In this paper,to study the mechanical responses of a solid propellant subjected to ultrahigh acceleration overload during the gun-launch process,specifically designed projectile flight tests with an onboard measurement system were *** projectiles containing dummy HTPB propellant grains were successfully recovered after the flight tests with an ultrahigh acceleration overload value of 8100 *** onboard-measured time-resolved axial displacement,contact stress and overload values were successfully obtained and *** compression tests of the dummy HTPB propellant used in the gunlaunched tests were carried out at low and intermediate strain rates to characterize the propellant's dynamic properties.A linear viscoelastic constitutive model was employed and applied in finite-element simulations of the projectile-launching *** the launch process,the dummy propellant grain exhibited large deformation due to the high acceleration overload,possibly leading to friction between the motor case and propellant *** calculated contact stress showed good agreement with the experimental results,though discrepancies in the overall displacement of the dummy propellant grain were *** dynamic mechanical response process of the dummy propellant grain was analysed in *** results can be used to estimate the structural integrity of the analysed dummy propellant grain during the gun-launch process.
