摘要

Iran announced that it tested a new satellite launch vehicle (SLV) called the Zoljanah for the first time on 1 February, saying it uses a new, more powerful solid-propel-lant motor.The rocket was shown being launched from the pad at the Khomeini Space Centre in Sem-nan that is usually used for Safir SLV launches, but the first stage was not seen separating in what was described as a sub-orbital test.The new SLV is 25.5 m long and weighs 52,000 kg, according to specifications shown on Iranian television. The first two stages are 150 cm in diameter and use a solid propellant; the third has a 125 cm diameter and uses liquid fuel. The solid motor has a thrust of 74,000 kgf, enabling the SVL to put a 220 kg payload into a 500 km orbit.Ahamed Hosseini, the spokesman for the ministry of defence's aerospace department, said this is the most powerful solid motor developed by Iran and that it could be increased to about 100,000 kgf.
