Drag acts ?
3 Drag acts Parallel to relative wind. 4 Lift acts Perpendicular to relative wind. 5 All other factors of importance remaining constant when speed increased Perpendicular to relative wind. 6 To put into a forward flight motion an unmanned 'rotary wing' aircraft You have to tilt main rotor plane of rotation ahead. Rotary wing = helicopter. 7 Lift Perpendicular to unmanned aircraft path. Rotary wing = helicopter. 8 To put in a forward motion an unmanned multi rotor aircraft Speed of rotation of front rotors must be reduced. Rotary wing = helicopter. 9 To yaw to left or to right an unmanned multi rotor aircraft Engines located on same axis must turn faster. Rotary wing = helicopter. 10 To generate a roll to left on an unmanned multi rotor aircraft Engines located on left must be reduced. Rotary wing = helicopter. 11 To generate a roll to right on an unmanned multi rotor aircraft Engines located on right must be reduced. Rotary wing = helicopter. 12 In hovering flight with an unmanned multi rotor aircraft All engines must spin at same speed. Rotary wing = helicopter. 13 For an unmanned multi rotor aircraft flight stability Provided reverting direction rotation of propellers. Rotary wing = helicopter. 14 As a multi rotor or a 'rotary wing' unmanned aircraft accelerates its attitude becomes Provided reverting direction rotation of propellers. Rotary wing = helicopter. 15 The movement of an unmanned aircraft about its lateral axis known as Provided reverting direction rotation of propellers. Rotary wing = helicopter. 16 The movement of an unmanned aircraft about its normal vertical axis known as Provided reverting direction rotation of propellers. Rotary wing = helicopter. 17 Rolling the rotation of aircraft about its Provided reverting direction rotation of propellers. Rotary wing = helicopter. 18 For a rotary wing aircraft helicopter tail rotor has following function To control rotation of airframe on yaw axis. Rotary wing = helicopter. 19 For an unmanned aircraft manoeuvrability Usually depends on its payload distribution. Too much stability will affect manoeuvrability if positioning of a camera or any load carried not correctly done manoeuvrability will be affected. 20 The statement that defines authorized maximum take off mass mtom Maximum take off mass authorized the manufacturer of an aircraft at take off. Too much stability will affect manoeuvrability if positioning of a camera or any load carried not correctly done manoeuvrability will be affected.
