Origami paper plane designed by Takuo Toda. Japanese scientists and origami masters considered in 2008 launching a flotilla of paper planes from space. [2] The launch was tentatively slated for 2009 [3] from the International Space Station [4] 250 miles above Earth.
A simple folded paper plane Folding instructions for a traditional paper dart. A paper plane (also known as a paper airplane or paper dart in American English, or paper aeroplane in British English) is a toy aircraft, usually a glider, made out of single folded sheet of paper or paperboard.
The Paper Aircraft Released Into Space (PARIS) project was a privately organized endeavour undertaken by various staff members of the British information technology website The Register to design, build, test, and launch a lightweight aerospace vehicle, constructed mostly of paper and similar structural materials, into the mid-stratosphere and recover it intact.
A paper plane is a toy aircraft (usually a glider) made out of paper or paperboard. Model glider aircraft are models of aircraft using lightweight materials such as polystyrene and balsa wood . Designs range from simple glider aircraft to accurate scale models , some of which can be very large.
Subcuticular stitch. A continuous suture where the needle enters and exits the epidermis along the plane of the skin. This stitch is for approximating superficial skin edges and provides the best cosmetic result. Superficial gapping wounds may be reduced effectively by using continuous subcuticular sutures. [15]
Aeronautics is the science or art involved with the study, design, and manufacturing of air flight-capable machines, and the techniques of operating aircraft and rockets within the atmosphere. While the term originally referred solely to operating the aircraft, it has since been expanded to include technology, business, and other aspects ...
Paper aeroplane; Radio-controlled glider; Rocket glider; Wingsuit; The main human application is currently recreational, though during the Second World War military gliders were used for carrying troops and equipment into battle. The types of aircraft that are used for sport and recreation are classified as gliders (sailplanes), hang gliders ...
Finally, aerodynamic problems may also be classified by the flow environment. External aerodynamics is the study of flow around solid objects of various shapes (e.g. around an airplane wing), while internal aerodynamics is the study of flow through passages inside solid objects (e.g. through a jet engine).
