VERTICAL CLIMB
A momentum method for computing the power required in a vertical climb in excess of that required to hover at the same conditions was derived in Chapter 2. The equation is:

Gross Weight, lb FIGURE 4.35 Hover Ceiling with Takeoff Power |
This equation has been evaluated for the example helicopter by equating it to the excess power available and the resultant vertical rate of climb as a function of altitude is shown on Figure 4.36.
Figure 4.37 shows the same calculations as a function of gross weight at two conditions of usual interest: sea level, standard; and 4,000 ft, 95°F.
