Ryan XV-5 was one of several planes attempting to produce an aircraft that can land like a helicopter and fly like a jet. 2 prototypes were built, with 1st being flown in May 1964 and tests continuing until 1971. The plane successfully proved the concept of ducted lift fans, and helped in better understanding of VTOL (Vertical Take Off and Landing) aircraft operation. Propelled by 2 11.8kN J85 turbojets from General Electric. GE also provided lift fans, 2 bigger X353-5 in the wings, and one smaller in the nose. Its legacy goes beyond VTOLs. Combination of turbojet and high-diameter fan pawed the way for TF-39 - GE's first high bypass ratio engine that was put under the wings of colossal C-5 Galaxy. TF-39 is better known thanks to its civilian derivatives - #cf6, still flying and not willing to retire anytime soon, and #lm2500 and #lm6000 marine and industrial gas turbines. Concept of ducted lift fans is being considered for some of eVTOLs, i.e. by ODONATA

Axial-flow Turbojet Engine A variable area nozzle helps to adjust the exit pressure of the combustion gases to ambient pressure. When they leave the turbine, the combustion gases have still some remaining pressure which is converted into speed by a convergent contour of the nozzle. . . . . #generalelectric #FAA #aviation #avionics

Humans have always dreamt of taking to skies and his exploration begins with Icarus wing's to Montgolfier brother's hot air hydrogen ballon in 1870's to 1903 Wright brother's glider flight although the distance they covered was mere 852 feet and were airborne for 49 seconds in comparison to today's Singpore Airlines flight that flies non-stop a remarkable distance of ~15000 KM between Changi & JFK. Airlines are fueled by Aviation fuel that are determined by energy content and combustion quality that allows them the range & thrust. The presence of napthalene, & acenaphthene not more than 5 % in aviation fuel is critical as it impacts its combustion qualtity and Did you know PerkinElmer UV Spectrometer are used to analyze the maximum amount of Napthalenes present in Aviation fuel.  #Aviationfuel #airlineindustry #UVspectrometer Image Credit: Shutterstock (Neiuwland)

VerdeGo Aero has been awarded a $1.9M Sequential Small Business Innovation Research (SBIR) Phase II Tactical Funding Increase (TACFI) contract with the United States Air Force to build and test the first prototype VH‑3 (185 kW) hybrid-electric powerplant that conforms to a production-intent configuration. The award was issued by the Air Force Life Cycle Management Center Mobility Directorate (AFLCMC/WLM) in cooperation with AFWERX, supported by the Air Force Research Laboratory (AFRL). The contract will result in the completion and trialing of the first production VH‑3 hybrid powerplant that builds on refinements from full-scale prototypes operational since 2020. Following the testing of this version, VerdeGo will have the capability to deliver small volumes of hybrid power sources to clients requiring energy for their ground and flight test programs.

Aircraft Fuel System - An Ultimate PDF Guide Download PDF at https://lnkd.in/d2m7q6G2 Aircraft fuel system is a system which enables or allow the airport staff to deliver, pump and even manage fuel to propulsion system and APU of aircraft is known as an aircraft fuel system. Additionally, these kinds of systems may vary based upon different performance of an aircraft. Apart from this the key function of this system are, it works as a shut-off valve and it also enables pilot select, which tank would feed the engine of aircraft. The key drivers for the aircraft fuel system market are, increasing deliveries of aircrafts, rising production of aircraft, technological advancement into refueling systems. #fuelsystem #fuel #aircraftfuel #aviation

Another good find by Gary Vermaak. This listing of eCTOL aircraft that look to be “coming soon” includes the Pipistral Velis Electro that is already certified. The others not on the list that I would include are: 1. ACS SORA-e 2. Aura Aero Integral 2. Heart Aerospace ES-19/30 3. Regent Craft Viceroy / Monarch 4. Volt Aero Cassio 1 The General Aviation / Personal Air Vehicle market is not insignificant and as the article points out the impact on the environment is also not something to overlook. The maintenance cost (fueling/electri motor overhaul) should be a big positive while the replacement of the batteries and initial cost look to be about the same as other GA / regional aircraft. This market is low hanging fruit for electric aviation as the political climate pushes for zero carbon footprint mobility. #aam #ectol #ram #pav #singleseatconsulting

Russian engine maker unveils cutting-edge aircraft engine "The state-of-the-art 177S engine for tactical aircraft boasts improved characteristics and is of the fifth generation class," the press service said ZHUHAI, November 12/ The United Engine Corporation (UEC) has unveiled the fifth generation of its 177S engine at the Airshow China 2024, the company’s press service says. "The global premiere of the high efficiency fifth generation 177S engine, which increases the flight range of tactical aircraft, will take place in China. The state-of-the-art 177S engine for tactical aircraft boasts improved characteristics and is of the fifth generation class," the press service said. The engine's improved fuel consumption rate in all operating conditions reduces costs, UEC said. "Furthermore, the engine supports the increased power consumption for electronic systems of modern airplanes. The powerplant also increases their flight range," the corporation noted. UEC also showcases full-size mockups of new AL-31FN Series Five and SM-100 engines to foreign partners. "The engines presented in China have several characteristics marking them as fifth generation. Furthermore, breakthrough engineering solutions enable their optimization to meet customer requirements and expand the set of options. An indisputable advantage of Russian engines is the opportunity to upgrade prior generation engines to the cutting-edge version during the overhaul. Their lifetime or thrust can be increased in such cases," CEO of UEC Alexander Grachev said. #business #finance #financialservices
