Today, the unexpected unearthing of theTerracotta Armya hoard of legendary, life-sized clay soldiersintended to fill an emperor's elaborate mausoleumis renowned as one of the world's greatest archaeological events. Discovered in northwestern China and dating back to its first dynasty, the ceramic figures have shed light on the country's ancient artistic practices and age-old burial rituals.
In addition to offering a glimpse into Imperial China's distinctive approach to funerary art, the sculptures are also celebrated for their scaleboth in terms of each individual sculpture's height and of the group as a whole.
In246 BCE,Qin Shi Huang, China's first emperor, took the throne at just thirteen years old. As ruler of the first Imperial Empire, he is credited with several accomplishments, including standardized scripts and coins, the construction of the Great Wall, and the overall expansion and unification of the state.
To celebrate his triumphs and memorialize his life, he ordered the construction of a necropolis inXi'an, a region dotted with jade mines and rich in gold. He envisioned a complex mausoleum filled with his precious earthly possessionsincluding rare jewels and architectural modelsas well as thousands of specially-made terracotta soldiers to protect him in the afterlife.
For centuries,Qin Shi Huang's massive mausoleum remained undetected. However, in 1974, workers stumbled upon a large sculpture of a terracotta warrior while digging a well. Prompted by this surprising find, archaeologists began to explore the area, resulting in the discovery of thousands of similar soldiers in four pits.
Designed with an impressive level of detail, each figure is a one-of-a-kind work of art. The life-sized sculptures vary in height according to military ranking, with their uniforms, hairstyles, and even facial shapes and expressions following suit.
In addition to the 8,000 soldiers themselves, 130 ceramic chariots and 670 horses were also found in the necropolis. Similarly, clay figures of dancers, acrobats, and musicians were also unearthed, though these whimsical figures are greatly outnumbered by the stoic army.
Historians theorize that the heads and bodies of the warriors were made via assembly line production. This entails that each individual part, such as the arms and legs, were made independently of one another to speed up manufacturing. Then, after being fired in the kiln, these various completed parts were assembled into one figure.
Additionally, many of the terracotta warriors originally held real weapons, such as swords, spears, crossbows, and lances. Although most of these historical artifacts have been stolen, 40,000 items still remain for historians to study.
While the vast majority of the terracotta soldiers remain on-site, ten have recently appeared in overseas exhibitions, allowing international audiences to see the sculptures in-person and offering a new generation the rare chance to view the figures up close (the Asian Art Museum).
Similarly, the sculptures also inspire contemporary artists, manifesting as reproductions made out of everything from pizza doughtopaper lanterns. Regardless of material or motive, these modern reinterpretations prove the lasting legacy of the amazing ancient artifacts.
Sand making production line is also called sand and stone production line. And the sand production line is a kind of special equipment for producing construction sand and stone. The sand making machine for sale is often needed in many fields, and this processing line can meet the requirements of simultaneous production of stone and artificial sand.
Compared with traditional sand making machine, Aimixs sand manufacturing process can save 50% energy. The sand manufacturing plant can crush rock, sand, gravel and other materials into various size in accord with the requirement of construction sand. Sand made by sand production line has uniform size and high compression strength, and this kind of sand is much more in line with the construction requirements than the sand processed by the ordinary hammer sand crusher machine.
Firstly, the feeding system. The system send raw material to sand crusher and sand screening machine. According to crush and screen process, feeding equipment includes vibrating feeder and other types of feeding machines.
Secondly, the crushing system. The system is the heart of the whole set of sand processing equipment. The work of sand crushing plant system is to crush different varieties of ore raw materials into the required size of the finished product. A complete stone production line includes many crushers. These crushing machines have different functions, and complete the crushing operation together.
Thirdly, the screening and transporting system. The system screens the ore which are crushed by crushing machinery. In the compound sand and stone production line, sand and stone need to be separated, and the separated material needs to be transported to the respective site. The sand screening equipment used in this process is generally a linear vibrating screen or other sand sieve machine.
When sand making production line is working, large pieces of stone stored in the silo are transported by the vibrating feeder into the jaw crusher for crushing coarsely. The belt conveyor delivers the coarsely crushed materials into the cone crusher (or impact crusher) for crushing. And then the belt conveyor carries the crushed materials to the vibrating screen for screening. The finished sands(materials above the sieve) are transported by the belt conveyor to the sand washing machine for washing, and then they are sent to the finished product stack with belt conveyor. Large particles stone(materials under the sieve material) are delivered by the belt conveyor to the vertical mobile impact crusher (sand making machine) for crushing finely. Finely crushed stones will be sent by the belt conveyor again into the vibrating screen for screening. In this way, closed loops are formed. This is how do you make sand with a sand processing line.

The Lower Tier Air and Missile Defense Sensor, commonly called LTAMDS, is a radar designed to defeat advanced and next-generation threats including hypersonic weapons, or those that fly faster than a mile a second.
That was the thinking behind the Soldier Touchpoint, a September meeting of a group of Army soldiers and the Raytheon Missiles & Defense team that is building the Lower Tier Air and Missile Defense Sensor, called LTAMDS, a next-generation radar designed to defeat newer threats such as hypersonic weapons.
The recent delivery of the first full-scale LTAMDS to the test site signifies LTAMDS is hitting all the marks, Raytheon Missiles & Defense's U.S. Requirements and Capabilities Director Bob Kelley said. The actual radar is sensing, in less than a year from contract award.
Providing the warfighters early input during the design phase of the system gives Raytheon Missiles & Defense an unparalleled ability to deliver the right capability, at the right time, to the U.S. Army, said Eric Maule, a manager in U.S. Requirements and Capabilities with Raytheon Missiles & Defense. Maule participated alongside the U.S. government during this event.
A similar process informed the design and production of another Raytheon Missiles & Defense product called the Warfighter Machine Interface, or WMI, a user-friendly control system for the Patriot air and missile defense system. Soldiers provide feedback to the designers and engineers to ensure the system meets user expectations.
The Army arrived in force with a diverse team of soldiers, including personnel from the Air and Missile Defense test detachment, Army Capability, Army Futures Command, and the Program Executive Office Missiles and Space. This team was eager to roll up their sleeves and help clarify user concepts of operations and employment requirements, Maule said.
This and subsequent Soldier Touchpoint events provide Raytheon Missiles & Defense with an unprecedented opportunity for user involvement, said Justin Weissert, P3I sustainment technical lead for Raytheon Missiles & Defense. Weissert was a key organizer for the soldier Touchpoint event.
The LTAMDS team thinks in terms of we as in we are in it together and were doing it with the Army, Kelley said. It is a complete collaboration. For example, the Army embeds in the LTAMDS technical and production teams. This way they join program meetings and actively engage if and when any challenges may come.
Master Sergeant Derrick Lee, a former first sergeant and now Operations and Capability Development noncommissioned officer at the Air and Missile Defense cross-functional team, knows all too well the behind-the-scenes complexity of getting the right people to the right place at the right time.
Its a true testament to this team, their unwavering commitment to the program, and their ability to adapt to any circumstance, saidBill Patterson, the LTAMDS program area director with Raytheon Missiles & Defense. Without a doubt, they are up to the challenge.
The U.S. Army sought a next-generation radar to help defeat increasingly complex and technologically advanced threats, like hypersonic weapons, or those that fly faster than a mile a second. Raytheon Missiles & Defense, one of four business of Raytheon Technologies, answered the call with the revolutionary LTAMDS.
And how quickly it has evolved. The Army selected Raytheon Missiles & Defense to provide its next-generation radar in October 2019. Raytheon Missiles & Defense built the first radar antenna array less than 120 days after the award.
The LTAMDS is a 360-degree radar that uses active electronically scanned array, or AESA, and gallium nitride, a circuit material that strengthens the radar signal and enhances its sensitivity. for longer range, higher resolution and more capacity. The radar provides greater capability against proliferating and more stressful threats. The company has made significant investments over the past two decades in AESA technology, gallium nitride technology and advanced manufacturing.
