Web14 de fev. de 2024 · This paper analyzes the nozzle start-up of the von Kármán Institute Longshot, an impulse hypersonic gun tunnel, using a combination of the Lagrangian L1D code (used to model the initial compression process of the test gas into a reservoir by an inertial piston) and unsteady Reynolds-averaged Navier–Stokes simulations to model the … WebLongshot differs from a conventional gun tunnel in that a heavy piston is used to compress the nitrogen test gas, which is then trapped in a reservoir at the end of the barrel at peak pressure and temperature by the closing of a system of …

WebResults on a hyperboloid-flare model tested in a new hypersonic wind tunnel with adiabatic compression AT-303 based at ITAM SB RAS at M ∞ = 10 and 15 and in a wide range of Reynolds numbers are presented. Pressure and heat-flux distributions along the model are compared with data obtained previously in various European hypersonic wind tunnels … Web16 de abr. de 2016 · The static pressure in the VKI Longshot hypersonic wind tunnel depends on the selected test conditions, but is expected to never exceed 1000 Pa. In addition, the relatively small size of the probes constrains the space available for embedded instrumentation.
