2.2.3. Determination of the Geometry of the Seals

For the determination of the spokes of the seals, the hypothesis of linear dependence between the diameters of the seals and the blade tip diameter was assumed. This hypothesis is satisfactorily verified for the front seal while exhibiting less feedback when applied to the rear seal. Given the modest influence of these parameters on the evaluation of volumetric returns, the approximation was considered acceptable. The relations used to evaluate the diameters of the seals as a function of the inlet blade tip diameter are as follows:

$$d\_f = 1.3031 \, d\_{1p} \tag{36}$$

$$d\_b = 1.3138 \, d\_{1p} \tag{37}$$
