In a nose shape, reference numerals 1, 2 and 3 denote a tip region, an intermediate region and a rear region, respectively. The change rate of the sectional area from the tip toward the rear end is maximal in the tip region 1 and progressively decreases towards the intermediate region 2 and the rear region 3. <IMAGE></p> |
