<Craft Summary>

<weight>
Material of craft body:Dry Carbon-Fiber-Reinforced Plastic specific gravity=1.65gw/cm^3=1650kgw/m^3,    Monocock body, Blended Winged Model, Double Delta Wing Angle of inclination=81(deg) and 73(deg), 

V-tail Wing, with 30(deg) dihedral angle,  Craft air frame weight:thickness=5mm,  Frame cylinder weight=(1.5^2/2-1.495^2/2)xpx12.5x1650=243kgw,  Frame conical weight =[(1.5/2)^2-(1.495/2)^2]x(p/3)x6x1650=39kgw
Weight of wing,tail-wing,dummy tail-wing,canopy(estimated)<200kgw,  Weight of body=200+243+39=482kgw,  Body weight <500kgw. Weight of Landing Gear:main & nose have to be kept<1500kgw
Weight of hydraulic system have to be kept<1500kgw, Weight of thruster rocket have to be kept<1000kgw, Weight of avation radio, radder, avionics have to be kept<100kgw,

Weight of life support system have to be kept<100kgw

Weight of drug parachute have to be kept<50kgw
Total empty weight of craft(except crews with pressurized suit) have to be kept <4900kgw,  crews included have to be kept<5200kgw, Weight of LES < 1500kgw, LES drug parachute < 50kgw,

Total equiped weight of craft<6750kgw
 <Lifting summary>
W=L=5200kgw
<wing section>
symmetric wing(NACA63(02)-015) or flat plate wing
*Flat plate: 1.Lift Coefficient of Stall=1.2
                      2.Optimal Attack Angle a =6(deg) on CL-a curve
                      3.Lift Sloop=2pa(rad)
                      4.Lift Coefficient CL=Daple           
                                            Da:Induced Angle of Two-dimentional air foil
                                            l:Aspect Ratio
                                           e:aerodynamic efficiency
<Flight Sequence>
Max Alititude=30000m           (W/g)(dV/dt)=F-D-W     
Max Velocity<1500m/s          (dV/dt)=F/m-D/m-W/m=(F-D-W)/m
Max Distance<200km            v=|((F-D-W)/m)dt=t(F-D-W)/m
with FLAT EARTH model
Now,cause,specification of booster is not decided, trust F is not abivious.
If acceleration increases zero to 9.8 x 2m/s^2 , crews feels variation of G is changed 1G to 3G in a second.
After ignition, acceleration is increased to 9.8 x 2m/s, then key lock on the launch pad is released means lift off.
Acceleration is 2 x 9.8m/s^2, thus, vehicle starts to rise at an acceleration of 9.8m/s^2=1G.
