Extendable wing

An aircraft, comprising:

• an aircraft body;
• an engine coupled with the aircraft body, the engine being constructed and arranged to provide power for forward flight;
• and
• an aircraft wing apparatus coupled with the aircraft body, the aircraft wing apparatus including:
• a plurality of wing-skin sections including a first wing-skin section and a second wing-skin section;
• an extendable spar assembly including a first spar member coupled with the first wing-skin section and a second spar member coupled with the second wing-skin section;
• and
• a controller constructed and arranged to move the second spar member to predefined positions relative to the first spar member to place the plurality of wing-skin sections into predefined configurations, the predefined configurations including a stowed configuration, a first deployed configuration, and a second deployed position that is different from the first deployed position;
• wherein the controller includes:
• an actuation assembly including a pulley wheel and a pulley cable, the pulley wheel being disposed at an outer portion of the first spar member, the pulley cable interfacing with the pulley wheel and having an end coupled with an inner portion of the second spar member;
• and
• a set of motors constructed and arranged to actuate the pulley cable to extend the second spar member relative to the first spar member.

A method of controlling an aircraft wing apparatus coupled with an aircraft, the method comprising:

• accessing a controller constructed and arranged to operate an extendable spar assembly of the aircraft wing apparatus, the extendable spar assembly including a first spar member and a second spar member, the first spar member being coupled with a first wing-skin section of a plurality of wing-skin sections, the second spar member being coupled with a second wing-skin section of the plurality of wing-skin sections;
• moving the second spar member to a first predefined position relative to the first spar member to place the plurality of wing-skin sections from a stowed configuration into a first deployed configuration;
• and
• moving the second spar member to a second predefined position relative to the first spar member to place the plurality of wing-skin sections into a second deployed configuration, the first deployed configuration being different from the second deployed configuration;
• wherein the controller includes:
• an actuation assembly including a pulley wheel and a pulley cable, the pulley wheel being disposed at an outer portion of the first spar member, the pulley cable interfacing with the pulley wheel and having an end coupled with an inner portion of the second spar member;
• and
• a set of motors constructed and arranged to actuate the pulley cable to extend the second spar member relative to the first spar member.
