We study the helicity dissipation and spectrum on the basis of an asymptotic model introducing a dependence of the angle between turbulent vorticity and velocity components on the governing parameters into it. This leads to helicity spectra similar to those observed experimentally and obtained by DNS model computations by various authors.
