The use of an aircraft (10), the propulsive force by means of a battery-operated electric motor (30) driven propeller (13) is carried out, as a remote controlled "mini - drone", the fuselage structure (11) as a support for an autopilot, which can be influenced by means of remote ...
A collective term for turbines in which the water jet enters the runner under a pressure exceeding the atmospheric value. The water flowing to the runner still has potential energy, in the form of pressure, which is converted into mechanical power along the runner blades. ...
Figure 1. Schematic for (A) an aircraft jet engine and (B) a land-based gas turbine. Because the 1939 origin of the gas turbine lies both in the electric power field and in aviation, there has been a profusion of “other names” for the gas turbine. For land and marine applications,...
An efficient and reliable flight Mach controller is specially needed for an Aircraft. A Flight Mach Fuzzy Controller (FMFC) based on modern Fuzzy control theory is designed for an Unmanned Aerial Vehicle (UAV) using a turbojet engine. Th... G Cui,H Zhang - Springer, Cham 被引量: 0发表...

However, these studies are characterized by the use of jet engines as the propulsion system for the target airplane. Moreover, it generally takes a lot of time to numerically calculate the optimal climb paths of the airplane, because the above studies dealt with a dynamic system. Therefore, ...
Conventional fuel-based powerplants including internal combustion and gas turbine/jet-based engines have been the go-to propulsion systems for automobiles and aircraft, respectively, but are constrained by their scalability and efficiency. Modern battery technology has enabled the commercial use of electri...
Aircraft propellers come in two basic types; fixed-pitch and variable-pitch. A fixed-pitch propeller, which is essentially a solid piece of material such as composite, metal or wood, is lower inperformance but makes the mechanical workings of the airplane very simple. On the other hand, the...
The majority of powered model airplanes use a propeller as part of their power system, and electric models are no exception. Some models use a ducted fan to simulate jet flight, and some even use propane or kerosene powered turbines (real jet engines). There are also a very few models tha...
The study of flow over a feathered propeller has many potential applications, including improving the efficiency and performance of aircraft and marine vehicles, reducing fuel consumption and emissions, and enhancing safety and control in extreme weather conditions.Similar...
