Aerospace winglet system are the system which are envisioned to enhance the effectiveness of fixed wing aircraft. There are various types of winglet devices that functions in different ways with an intention to lessen the drag of the aircraft by fractional recovery of the tip vortex energy. It also helps in improving aircraft handling characteristics and improves safety of the aircrafts. Winglet system increases the effective aspect ratio of a wing without increasing the wingspan. These systems help in increasing the lift generated at the wingtip and decreases the lift induced drag triggered by wingtip vortices, thereby enhancing the lift to drag ratio. It enhances fuel efficiency in powered aircraft and escalates cross country speed in gliders. Implementation of winglets results in lower CO2 emissions, greater fuel economyand lower costs for airlines.
The air pressure on the upperpart of the wing is less than the air pressure underneath the wing when an aircraft is in flight. The high pressure air below the wing rushes to the lower pressure areas on top that results in the creation of vortices adjoining the wing tips.

The aerospace winglet market is primarily driven by the enhanced takeoff and landing capability. The winglet helps in increasing operational efficiency of the aircraft which helps reducing the drag which is also an important driver in the global aerospace winglet system market. Another major driver in this market is the enhanced climate performance which means the winglet can operate smoothly even in hotter climate and temperature.
Regardless of various driving factors, there are some factors restraining the growth of aerospace winglet market globally. One of the major restraining factors is the issue in designing of the winglet. Due to technical designing issues the market is facing slow growth. Another restraining factor is the winglet retrofitting which means addition of new features to older winglets.
