This instrument cluster of electric generators and cabin pressurization system comes from a Boeing 727 authentic flight engineer panel. Looking at it more closely, it is not the least singular and original device. Indeed, the instruments are arranged as usual on a Boeing 727 carrying passengers about it has a cargo door opening! In the 1990s, UPS (then known as United Parcel Service) operated its B727 CARGO fleet only during weekdays, with planes remaining grounded on the two days of the weekend before resuming flights on early Monday mornings. In order to make these devices profitable, the company decided to operate charter flights with passengers to tourist destinations such as Cancun. Thus, the freight company converted the cabins of five of its B727s so that they could be reconfigured in a few hours to accommodate passengers with PSUs, seats, galleys and toilets on trays instead of cargo pallets. The aircraft which were thus transformed were the 727 registered N946UP, N947UP, N949UP, N950UP and N951UP. This panel comes from one of them. Completely restored in its original condition with all its components, this panel is presented on a specially designed pedestal painted with a textured powder coated in black. This aircraft’s part - a real Industrial masterpiece - will make a beautiful art decoration for your home or office.

Student design engineers often require a \"cookbook\" approach to solving certain problems in mechanical engineering. With this focus on providing simplified information that is easy to retrieve, retired mechanical design engineer Keith L. Richards has written Design Engineer's Handbook. This book conveys the author's insights from his decades of experience in fields ranging from machine tools to aerospace. Sharing the vast knowledge and experience that has served him well in his own career, this book is specifically aimed at the student design engineer who has left full- or part-time academic studies and requires a handy reference handbook to use in practice. Full of material often left out of many academic references, this book includes important in-depth coverage of key topics, such as: Effects of fatigue and fracture in catastrophic failures Lugs and shear pins Helical compression springs Thick-walled or compound cylinders Cam and follower design Beams and torsion Limits and fits and gear systems Use of Mohr's circle in both analytical and experimental stress analysis This guide has been written not to replace established primary reference books but to provide a secondary handbook that gives student designers additional guidance. Helping readers determine the most efficiently designed and cost-effective solutions to a variety of engineering problems, this book offers a wealth of tables, graphs, and detailed design examples that will benefit new mechanical engineers from all walks.
