Abstract
Provided in this disclosure is a portable night vision tunnel for operating a vehicle in a simulated night environment. The night vision tunnel is formed by assembling a plurality of modules on a driving surface to provide a darkened interior in which the vehicle can be driven. Each of the modules are formed of inflatable arch components each having a light-absorptive interior surface for creating the simulated night environment for operating the vehicle. A fastener arrangement connects each of the arch components to an adjoining one to form a single module. The tunnel includes a portal formed on an able arch component at a respective module proximate to the end of the tunnel. The portal admits the vehicle into the tunnel while maintaining the simulated night environment for operating the vehicle. An air circulation system ventilates and circulates air within an interior space of the tunnel.
