DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
Referring to the drawings, and initially to FIG. 1, a control system in 
accordance with the present invention is provided for a flight vehicle 90 
when landing or taking off and comprises a plurality of guiding devices 40 
each mounted on the ground for guiding the flight vehicle 90 and a 
plurality of support water jet generators 30 for supporting the flight 
vehicle 90 when landing or taking off. A supply device 10 is connected by 
means of a conveying tube 20 with the support water jet generators 30 and 
the guiding devices 40 for supplying pressurized water thereto. A first 
communication apparatus 500 is connected with the supply device 10 and is 
in communication with a second communication apparatus 502 which is 
mounted on the flight vehicle 90. 
Referring to FIGS. 3 and 4, each of the guiding devices 40 comprises a long 
range guiding water jet generator 410 including a plurality of first 
nozzles 414 each projecting a jet of water upwardly and a first 
illumination apparatus 412 projecting a plurality of beams of light 
upwardly each in concert with the jet of water projected from each of the 
first nozzles 414 so as to guide the flight vehicle 90 along a 
predetermined direction when the flight vehicle 90 is located at a longer 
distance relative to the guiding device 40 and a short range guiding water 
jet generator 420 including a plurality of second nozzles 424 each 
projecting a jet of water upwardly and a second illumination apparatus 422 
projecting a plurality of beams of light upwardly each in concert with the 
jet of water projected from each of the second nozzles 424 so as to guide 
the flight vehicle 90 along the predetermined direction when the flight 
vehicle 90 is located at a shorter distance relative to the guiding device 
40. 
Control devices 416 and 426 are respectively mounted in the long and short 
range guiding water jet generators 410 and 420 for controlling the 
illumination apparatuses 412 and 422. A computer 100 is in communication 
with the control devices 416 and 426. 
Referring to FIG. 5, each of the support water jet generators 30 includes a 
third nozzle 301 injecting a jet of pressurized water upwardly for 
smoothly supporting the flight vehicle 90 when landing. A control device 
302 is mounted on each of the support water jet generators 30 for 
controlling the amount and the direction of the pressurized water to be 
projected from the third nozzles 301 to the flight vehicle 90. The 
computer 100 is in communication with the control device 302. 
Referring to FIG. 2, the supply device 10 is provided for conveying water 
to the first, second and third nozzles 414, 424 and 301 (not shown) and 
comprises a pressure chamber 12 having water 106 and air 105 contained 
therein. A compressor 101 is mounted on the pressure chamber 12 for 
pressurizing the air 105 therein so as to compress and urge the water 
received in the pressure chamber 12 into the first, second and third 
nozzles 413, 424 and 301 via the conveying tube 20. A display instrument 
102 is mounted on the pressure chamber 12 for indicating an instantaneous 
value of the air pressure therein. A safety device 104 is mounted on the 
pressure chamber 12 for stopping operation of the compressor 101 when the 
air pressure in the pressure chamber 12 reaches a predetermined safety 
value. 
Referring to FIGS. 1, 3 and 6, a plurality of buffer devices 80 each 
include a contact board 8011 mounted on an underside of the flight vehicle 
90 for being supported by means of the jet of pressurized water projected 
from the third nozzle 301 of the support water jet generator 30. A 
plurality of collision sensors 8012 are mounted on each of the contact 
boards 8011 for sensing an impact force exerted on the contact board 8011 
by means of the bundle of pressurized water projected from the third 
nozzle 301. A plurality of display devices 600 are mounted on the flight 
vehicle 90 and in communication with the collision sensor 8012 for 
indicating a current value of the impact force exerted on the contact 
board 8011. 
In operation, an operator on the ground is able to detect an approach of 
the flight vehicle 90 by means of the communication equipment 500 via the 
communication equipment 502. Then, the computer 100 is able to operate the 
long range guiding water jet generator 410 of the guiding device 40 so as 
to project the jets of water together with bright light upwardly into the 
high sky in a radiating manner, thereby roughly guiding the flight vehicle 
90 along a predetermined travel direction when the flight vehicle 90 is 
detected to be located at a longer distance relative to the guiding device 
40. 
When the flight vehicle 90 is detected to be located at a shorter distance 
relative to the guiding device 40, the computer 100 is able to operate the 
short range guiding water jet generator 420 of the guiding device 40 so as 
to inject and project the jets of water together with bright light 
upwardly into the high sky, thereby precisely guiding the flight vehicle 
90 along the predetermined travel direction. Preferably, the beams of 
light projected from the short range guiding water jet generator 420 are 
alternated with different colors for facilitating guiding the flight 
vehicle 90. 
When the flight vehicle 90 is about to land on the ground, the computer 100 
is able to manipulate the support water jet generators 30 so as to project 
jets of pressurized water upwardly via nozzles 301 for urging a supporting 
force on the contact boards 8011, thereby smoothly supporting the flight 
vehicle 90 so as to land on the ground steadily. 
Conversely, when the flight vehicle 90 is about to take off, the computer 
100 is able to manipulate the support water jet generators 30 so as to 
inject jets of pressurized water upwardly via nozzles 301 for urging a 
supporting force on the contact boards 8011, thereby smoothly supporting 
the flight vehicle 90 so as to leave the ground steadily. 
Accordingly, by such an arrangement, the control system is provided for 
guiding and supporting the flight vehicle 90 smoothly so as to land or 
take off steadily. 
It should be clear to those skilled in the art that further embodiments of 
the present invention may be made without departing from the teachings of 
the present invention.
