Note (General): A new implicit finite-difference scheme for unsteady Euler equations is proposed. The quantities of the order of the square of the time-step are employed as unknowns of the scheme, which produces a "delta2 (delta-square)-form" of the algorithm. The present scheme has second-order time accuracy without iteration. The iteration process in the algorithm, which the scheme has as an option, improves the numerical accuracy and robustness. Numerical experiments show that the present scheme is very good not only for unsteady problems but also steady problems.
