If a seaplane has velocity at stall as V mph then, what will be the value of deadrise angle?(a) ɑdeadrise = 0.5*(v – 20) degree(b) ɑdeadrise = 0.5*(v / 20) degree(c) ɑdeadrise = 0.5*v degree(d) ɑdeadrise = 0.5*(v^2 – 20) degreeThis question was addressed to me during an interview.I'd like to ask this question from Landing Gear and Subsystems topic in section Landing Gear and Subsystems of Aircraft Design |

Answer» CORRECT choice is (a) ɑdeadrise = 0.5*(v – 20) degree The EXPLANATION is: When we USE V SHAPED bottom on SEAPLANE, deadrise is then defined as the height of the V and angle is called deadrise angle. Typically, deadrise angle can be approximated as follows, ɑdeadrise = 0.5*(v – 20) degree where, v is stall speed in mph. |
