Bō-hiya

picture info	Bō-hiya A was an early Japanese rocket launcher and development of the fire arrow. History and description Fire arrows of some type have been used in Japan as far back as the 6th century where they are said to have been used during a military campaign in Korea. Bows (yumi) were used to launch these early fire arrows. In 10th-century China, gunpowder was used to launch fire arrows, and this type of fire arrow was used against the Japanese by Mongolian naval vessels in the 13th century. In 1543, the Japanese acquired matchlock technology from the Portuguese, and the resulting firearms developed by the Japanese led to new means of launching fire arrows. These rocket-type bo-hiya had the appearance of a thick arrow with large fins, a wood shaft and a metal tip; they resembled the Korean chongtong, an arrow-firing cannon. Bo-hiya were ignited by lighting a fuse made from incendiary waterproof rope which was wrapped around the shaft; when lit the bo-hiya was launched from either a wide-b ...

	Ryūsei (signal Rocket) A is a traditional Japanese signal rocket. Summary A ''ryūsei'' fuselage is made from either pine softwood or a section of bamboo, and it is propelled by the combustion of gunpowder. The particular type of gunpowder used in ''ryūsei'' is formulated to burn slowly. ''Ryūsei'' are believed to have been developed by reverse engineering primitive Chinese gunpowder rockets left behind by the defeated Yuan armies after the Mongol invasions of Japan in the 13th century. However, there is another theory that ''ryūsei'' were invented locally by Japanese peasants. Because of this, they are sometimes called . In the 16th century, ''ryūsei'' rockets were used as smoke signals, and documents preserved at record the launch of a ''ryūsei'' in 1575. After the Second World War and occupation, American-directed bans on private possession of gunpowder nearly caused the extinction of ''ryūsei''. After many petitions, gunpowder for ''ryūsei'' was finally legalized again in 1972. ''Ry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Mysorean Rockets Mysorean rockets were an Indian military weapon. The iron-cased rockets were successfully deployed for military use. They were the first successful iron-cased rockets, developed in the late 18th century in the Kingdom of Mysore (part of present-day India) under the rule of King Hyder Ali. The Mysorean army, under King Hyder Ali and his son King Tipu Sultan, used the rockets effectively against the British East India Company during the 1780s and 1790s. According to James Forbes, Marathas also used iron-encased rockets in their battles. Their conflicts with the company exposed the British to this technology further, which was then used to advance European rocketry with the development of the Congreve rocket in 1805. Technology and deployment There was a regular rocket corps in the Mysore Army, beginning with about 1,200 men in King Hyder Ali's time. During the Second Anglo-Mysore War, Colonel William Baillie's ammunition stores are thought to have been detonated by a stra ...

picture info	Samurai Weapons And Equipment The samurai () were members of the warrior class in Japan. They were originally provincial warriors who came from wealthy landowning families who could afford to train their men to be mounted archers. In the 8th century AD, the imperial court downsized the national army and delegated the security of the countryside to these privately trained warriors. Eventually the samurai clans grew so powerful that they became the ''de facto'' rulers of the country. In the aftermath of the Gempei War (1180-1185), Japan formally passed into military rule with the founding of the first shogunate. The status of samurai became heredity by the mid-eleventh century. By the start of the Edo period, the shogun had disbanded the warrior-monk orders and peasant conscript system, leaving the samurai as the only men in the country permitted to carry weapons at all times. Because the Edo period was a time of peace, many samurai neglected their warrior training and focused on peacetime activities such as ...

picture info	Technology In Medieval Japan Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. The word ''technology'' can also mean the products resulting from such efforts, including both tangible tools such as utensils or machines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life. Technological advancements have led to significant changes in society. The earliest known technology is the stone tool, used during prehistory, followed by the control of fire—which in turn contributed to the growth of the human brain and the development of language during the Ice Age, according to the cooking hypothesis. The invention of the wheel in the Bronze Age allowed greater travel and the creation of more complex machines. More recent technological inventions, including the printing press, telephone, and the Internet, have lowered barriers to communication and ushered in the knowledge economy. Whil ...
