A |     Gandhinagar, Oct 19 (UNI) Prime Minister Narendra Modi is all set to unveil the Hindustan Turbo Trainer-40, the indigenous Basic Trainer Aircraft designed by Hindustan Aeronautics Limited here on Wednesday.

The Prime Minister will inaugurate India's biggest ever five day long defence exhibition DefExpo 2022 at Mahatma Mandir Convention and Exhibition Centre at around 9:45 AM and thereafter visit the India Pavilion to unveil the trainer aircraft.

The HTT-40 aircraft has state of art contemporary systems and has been designed with pilot friendly features.

The aircraft has already received its clearance certificate from Centre for Military Airworthiness and Certification (CEMILAC) based on extensive design evaluation, testing of aircraft systems and comprehensive flight testing carried out by HAL Flight Operations team along with pilots from IAF.

The project also set a record as the fastest to reach certification from the first flight.

In February last year, Hindustan Aeronautics Limited received a Request for Proposal (RFP) from the Indian Air Force for their Basic Trainers requirement at the Aero India 2021 in Bengaluru. The RFP was for 70 HTT-40 Basic Trainer Aircraft with provision for 38 more.

The trainer has more than 60 percent indigenous content and is supported by agencies such as Centre for Military Airworthiness and Certification (CEMILAC), Regional Director Aeronautical Quality Assurance (RDAQA), Aircraft and Systems Testing Establishment (ASTE) among others.

During the programme at the DefExpo 2022, the Prime Minister will also launch Mission DefSpace here to develop innovative solutions for the Defence Forces in the Space domain through industry and startups.

Besides, the Prime Minister will lay the foundation stone of Deesa airfield in Banaskantha district of Gujarat. As per sources, the air base, situated just 130 km from Pakistan border, will be operational by 2024.

The forward airforce base will add on to the security architecture of the country. Experts believe that the strategically located airbase will add teeth to the IAF's prowess along the western border.

Modi is on a two day visit to Gujarat on Wednesday and Thursday where he is set to dedicate and lay the foundation stone of projects worth around Rs 15,670 crore.

UNI ASU BAV。    4月22日7时至9时，迎来本年度第二个龙年龙月龙日龙时。

B | 据介绍，今年共会出现3次龙年龙月龙日龙时，分别在4月10日、4月22日和5月4日的7时至9时，这是使用传统干支和生肖纪法来标记年、月、日、时形成的有趣现象。转发收藏，愿你好运连连，万事兴“龙”！　　中国科学院紫金山天文台科普主管王科超介绍，甲乙丙丁戊己庚辛壬癸为十天干，子丑寅卯辰巳午未申酉戌亥为十二地支，它们排列成60个干支组合：甲子、乙丑……癸亥，以此记录年序与日序，如此循环往复。　　我国农历至今仍沿用干支纪年、纪日，农历年按干支纪法和生肖纪法命名，比如今年为甲辰龙年；农历日按数序纪法和干支纪法命名。

C | 王科超说，现在的农历以朔望月作为划分月份的标准，用数字来定月序，但在2000多年前，古人已采用十二地支来标记月份，并以冬至节气所在的农历十一月为子月，十二月为丑月，正月为寅月……以此类推，并配合天干使用。按照这种干支纪法，今年的正月十五也可称为：甲辰年丙寅月戊午日。　　我国古代同样也用干支纪时，即将一昼夜分为十二时辰，以十二地支循环纪时。对应到一天的24小时，两个小时为一个时辰，子时为23时至1时，丑时是1时至3时……亥时对应21时至23时。

D | 　　“我国古人又以十二生肖对应各个地支，今年为甲辰龙年，所谓龙月、龙日、龙时即为辰月、辰日、辰时。

E | ”王科超说，2024甲辰龙年的龙月里有3个龙日，因此将出现3个“龙年龙月龙日龙时”，分别在4月10日、4月22日和5月4日的7时至9时。　　龙年龙月龙日龙时就是辰年辰月辰日辰时　　了解了干支纪年和天干地支的搭配方法，就可以推算出龙年龙月龙日龙时。

F | 排在第五位的龙和辰对应，每60年有5个龙年。　　龙月就是在中国传统历法中一年也分为12个月，但是这个月是以朔望月作为标准来划分的。在2000多年前，古人就确定以冬至节气所在的月为子月依次排序，至下一年冬至所在月再为子月，闰月不计。秦汉以来，中国传统的农历将寅月作为正月即一月。所以冬至所在的子月是农历的十一月，因此将月份地支与生肖相配的话，一年中农历三月为辰月就是龙月。　　龙日是怎么回事？中国古代排列日期除了用123这样的数字计日，也使用干支计日的办法，这样每60日就有5个辰日，也就是5个龙日。2024甲辰龙年的龙月里有3个龙日龙时，分别在4月10日、4月22日和5月4日的7时至9时。　　（图源网络 中国小康网综合人民日报、羊城晚报、央视新闻客户端）。
