The NH90 helicopter is primarily made of composite materials, including carbon fiber and Kevlar. These materials are used for their high strength-to-weight ratio, which allows the helicopter to be both durable and lightweight. Additionally, the NH90 also incorporates various metals such as aluminum and titanium in its construction to provide structural support and enhance performance. Overall, the combination of these materials makes the NH90 a versatile and capable helicopter for a variety of missions. **

The operating costs for the NH90 are high due to several factors. Firstly, the NH90 is a complex and technologically advanced helicopter, which requires specialized maintenance and skilled personnel, leading to higher labor costs. Additionally, the NH90 has a high level of operational readiness and availability requirements, which necessitates frequent and thorough maintenance, contributing to increased operating costs. Furthermore, the NH90 has a relatively high fuel consumption rate, further adding to its operating costs. Finally, the NH90's extensive use of composite materials and advanced avionics also contribute to its high operating costs. **

Teachers work with a variety of tools, materials, and equipment in their daily work. Some common tools include whiteboards, markers, and projectors for delivering lessons. Materials such as textbooks, worksheets, and manipulatives are used to support student learning. Equipment like computers, printers, and audio-visual devices are also essential for creating engaging lessons and activities. Overall, teachers rely on a combination of traditional and modern tools to effectively educate their students. **

The NH90 helicopter has faced criticism for its high cost, delays in production, and technical issues. However, it is important to note that the NH90 also has many advanced features and capabilities, such as its ability to operate in various environments and its advanced avionics systems. While it has faced challenges, it is not necessarily as bad as it is always portrayed, and its performance can vary depending on the specific circumstances and requirements of the mission. **

The NH90 helicopter has been experiencing issues with its engine and gearbox, which have led to a series of fires. These fires have been linked to oil leaks and other technical malfunctions within the helicopter's systems. As a result, the NH90 has been grounded and is undergoing thorough inspections and repairs to address these safety concerns. **
