Abstract
The invention relates to a total inventive concept related to an aircraft and a submarine which are driven in a fluid based on a fluid mechanic principle, and provides a rudder of an aircraft and a submarine. Various aircrafts and submarines comprise different numbers of vertical fin rudders (1), back diving rudders (2) and front rudders (3), and the rudder provided by the invention has a continuous sharp-tooth and two-side edge opening shape, so that the fluid resistance to the rudder with a sharp point type cross section is small, and the rudder can replace a rudder with a line type cross section and large fluid resistance. Compared with the local fluid resistance to the conventional rudder of the aircraft and the submarine, the local fluid resistance to the rudder of the aircraft and the submarine is reduced, and the forward speed of the whole aircraft and the submarine is increased; and meanwhile, when a moving track is changed, maneuvering characteristics of the aircraft and the submarine are improved. The local fluid resistance to the rudder of the aircraft and the submarine is low, so that the rudder is light and labor-saving during operation, and energy consumption of reserves in the unmanned aircraft and submarine is reduced.

Ao Xiang sky: the animal origin of flight is probed into/Zhang Fucheng, Zhou Zhong and work.---Shanghai: Shanghai science tech publishing house, 2003.10. the 102nd page, " air dynamic behaviour generally refers in particular to the various streamline contour external forms (to reduce windage) of the object that moves in air.”
Aviation secret/journey frequently waits and writes.---Shanghai: Shanghai scientific popularization press, 2004.4. the 8th page, aircraft tail " its structure is comprised of two parts; be called ' stabilator ' with the fuselage immobile part that is fixed together; the rotary part in stabilator back is called ' rudder face ' ... empennage is divided into again horizontal tail Ji and vertical tail.Rudder face on tailplane is elevating rudder ... the empennage that is erected at back is called vertical tail, and the rudder face on vertical fin is called ' yaw rudder '.”
Same page, " along with the raising of air speed, and to the raising of air maneuver requirement, the rudder face area also requires continuous increase, causes many aircrafts to use flying tail instead, and some aircrafts have also designed twin vertical fin.
In aircraft tail in different poses and with different expressions, also have specially tailplane is moved on to before aircraft wing, be called front wing.”
From the above as can be known, the vertical fin wing rudder on aircraft, rear horizontal tail rudder, front wing rudder are all to include the rudder that quantity wherein differs on varied various concrete aircraft take aircraft as representative.
Vertical fin rudder, rear diving rudder, casing rudder are arranged on submarine.
During for the rudder on narration aircraft, submarine, the title call is consistent, here carry-on vertical fin wing rudder all cry vertical fin aircraft, submarine on rudder consistent with the vertical fin rudder on submarine.
The carry-on rear horizontal tail rudder rear diving rudder that all cry aircraft, submarine on consistent with the rear diving rudder on submarine.
The carry-on front wing rudder front rudder that all cry aircraft, submarine on consistent with the casing rudder on submarine, so just unified the call of title.
The 108th page of front " aviation secret " book, " aircraft designer also makes ' W ' serration with ' B-2A ' wing, empennage, and backward wave is deflected away from the U.S..”
" U.S. ' F-22 ' fighter plane that comes out recently ... wing, the trailing edge of empennage are serration, the spy becomes 27 degree with two vertical tail flares, and this is the critical angle of radio wave refration just." still; " U.S. B-2A type stealth bomber " from the 14th color page of this book front; on the 17th color page on the picture of " U.S. F-22 stealth fighter "; show they said " wing, empennage are made ' W ' serration "; " trailing edge of wing, empennage is serration "; be that the aircraft rear portion integral body that airfoil member and empennage parts two parts constitute mutually is " serration ", with serration covering block construction on fuselage and the zigzag structure on the airplane tail spout, all in order to reduce the volume reflection of radar wave, to make aircraft play recessive role.
With themselves picture that provides, prove U.S. B-2A type stealth bomber does not have serration on the trailing edge of U.S. F-22 stealth fighter empennage parts.
Summary of the invention
The technical problem to be solved in the present invention, all the technical total inventive concept that is mutually related that moves in fluid as aircraft, submarine according to fluid mechanics principle, proposing the object of invention of the rudder on aircraft, submarine, is by a kind of aircraft of fluid resistance, rudder on submarine of reducing is provided.
For addressing the above problem, the front shape that the invention provides the rudder on a kind of aircraft, submarine is the put the first edge on a knife or a pair of scissors rudders of shape structure of continuous pointed tooth both sides, adopt the rudder of this spline structure, the part of the rudder on aircraft, submarine is that the structure with fluid resistance few cusp formula cross section replaces the line formula cross section structure of Duoing than continuous cusp formula section fluid resistance.
As a further improvement on the present invention, the forward and backward position of the rudder on aircraft, submarine is all the continuous pointed tooth both sides shape structures of putting the first edge on a knife or a pair of scissors.
As another kind of improvement the of the present invention, the rear portion of the rudder on aircraft, the rudder of diving is the continuous pointed tooth both sides shape structures of putting the first edge on a knife or a pair of scissors.
Advantage of the present invention: the rudder structure on aircraft, submarine is simple, reduced the resistance of fluid to the rudder on aircraft, submarine, the rudder that operates on operating aircraft, submarine switches up and down, during left and right commutation running orbit, can be softer, lighter, more laborsaving, quicker, can promote the maneuvering performance of aircraft, submarine transformation running orbit.By reducing the partial fluid resistance of the rudder on aircraft, submarine, can promote the speed of advance of aircraft, submarine integral body.For unmanned vehicle, submarine, more laborsaving owing to having reduced the resistance of fluid to rudder when the rudder on instruction unmanned vehicle, submarine operates, can save the energy resource consumption that stores on unmanned vehicle, submarine.
Below in conjunction with accompanying drawing, the rudder on aircraft of the present invention, submarine is done carefully to describe furtherly.
