Heck of a rocket ship you have there Johnny.The travel between Earth and Alpha Centauri star, including acceleration and deceleration, will take 2 years and 11 months and a decaborane consumption of 275.2Kg, reaching a maximum velocity of 3.27131×10E9Km/h, about three times the speed of light, at the midway.
Engineering is the art of making what you want from what you can get at a profit.
