Finally , the elemental errors are summed up to obtain the 95 % coverage ( URSS ) of the measured thrust . Table 2 shows the 95 % coverage for T and T - To for each test . For example , we have the following results for Test No.2609 .

Starting at low advance coefficient , the mean thrust coefficient originally increases until a maximum is reached at approximately J = 0.3 to 0.4 , then it diminishes gradually , approaching a value of zero above J = 0.8 .
