Abstract An experimental apparatus for investigating Rayleigh-Taylor instability in the transition layer between two gases at accelerations g ∼ 105g0 (g0 is the acceleration of gravity) is described. The constantly acting acceleration is communicated to the contact zone by the compression wave formed ahead of a flame front. The linear stage of development is investigated together with the effect of the thickness δ of the contact zone. It is shown that on the interval 0.3λ 〈 δ 〈- λ (λ is the wavelength of the disturbance at the edge of the contact zone) the rate of growth of the perturbation amplitude γ ≈ 0.5γ0, where γ0 is the amplitude growth rate for media separated by an interface with a discontinuous change of density.
