F-15EX First Flight Clears Path for Deliveries to U.S. Air Force
press release
- Newest U.S. Air Force fighter completes 90-minute test flight
- Deliveries to begin this quarter, less than nine months after contract award
ST. LOUIS, Feb. 2, 2021 — The new Boeing [NYSE: BA] F-15EX fighter jet completed its first flight today, paving the way for the early delivery of the first two jets to the U.S. Air Force later this quarter. The jet took off and landed from St. Louis Lambert International Airport, completing a 90-minute test flight before returning to the airport.
Boeing F-15 Chief Test Pilot Matt Giese checked out the multirole jet’s avionics, advanced systems and software. A test team monitoring the data collected during the flight in real time confirmed that the aircraft performed as planned.
“Today’s successful flight proves the jet’s safety and readiness to join our nation’s fighter fleet,” said Prat Kumar, Boeing vice president and F-15 program manager. “Our workforce is excited to build a modern fighter aircraft for the U.S. Air Force. Our customer can feel confident in its decision to invest in this platform that is capable of incorporating the latest advanced battle management systems, sensors and weapons due to the jet’s digital airframe design and open mission systems architecture.”
The fighter’s digital backbone means it can serve as a testbed for future technology insertion, a key capability for the Air Force. Modern variants of the F-15 also include fly-by-wire flight controls, an all-new digital cockpit, modern AESA radar and the ADCP-II, the world's fastest mission computer. The F-15EX, the most advanced version to date, features the Eagle Passive/Active Warning and Survivability System electronic warfare system to improve mission effectiveness and survivability for operators.
In July, the Air Force awarded Boeing a contract to build the first lot of eight jets. Future plans call for as many as 144 aircraft. For more information on Defense, Space & Security, visit www.boeing.com. Follow us on Twitter: @BoeingDefense and @BoeingSpace.

Rolls-Royce conducts first tests of 100% sustainable aviation fuel for use in business jets
https://www.rolls-royce.com/media/press-releases/2021/01-02-2021-business-aviation-rr-conducts-first-tests-of-100-precent-sustainable-aviation-fuel.aspx
Rolls-Royce has conducted the first tests of 100% Sustainable Aviation Fuel (SAF) in a business jet engine, as part of our ongoing ambition to play a leading role in enabling the sectors in which we operate reach net zero carbon by 2050. The tests on our latest business aviation engine in development, the Pearl 700, in Dahlewitz, Germany, come just weeks after unblended SAF was successfully used for the first time in engine ground tests on a Trent 1000 engine in Derby, UK.
This test demonstrates once again that our current engines for large civil and business jet applications can operate with 100% SAF as a full “drop-in” option, laying the groundwork for moving this type of fuel towards certification. At present, SAF is only certified for blends of up to 50% with conventional jet fuel and can be used on all current Rolls-Royce engines.
The SAF that was used in the tests was produced by low-carbon fuel specialist World Energy in Paramount, California, sourced by Shell Aviation and delivered by SkyNRG. This unblended fuel has the potential to reduce net CO2 lifecycle emissions by more than 75% compared to conventional jet fuel, with the possibility of further reductions in future.
Dr Joerg Au, Chief Engineer – Business Aviation and Engineering Director Rolls-Royce Deutschland, said: “Sustainable aviation fuels have the potential to significantly reduce the carbon emissions of our engines and combining this potential with the extraordinary performance of our Pearl engine family brings us another important step closer to enabling our customers to achieve net zero carbon emissions.”
The highly efficient Pearl 700 combines the Advance2 engine core, the most efficient core available across the business aviation sector, with a brand-new low-pressure system, resulting in an 8% increase in take-off thrust at 18,250lb compared to the BR725 engine. The engine offers a 12% better thrust-to-weight ratio and 5% higher efficiency, while maintaining its class-leading low noise and emissions performance.
It brings together innovative technologies derived from the Rolls-Royce Advance2 technology demonstrator programmes with our experience from the Rolls-Royce BR700, today’s leading engine family in business aviation. This includes a highly-efficient 51.8” blisked fan, a high pressure compressor with a market-leading pressure ratio of 24:1 and six blisked stages, an ultralow emissions combustor, a two-stage shroudless high pressure turbine and an enhanced four-stage low pressure turbine that is one of the most efficient and compact in the industry.

Virgin Galactic sets a new flight window for VSS
press release
https://www.virgingalactic.com/articles/virgin-galactic-flight-test-program-update/
Flight Window Opens on February 13
Virgin Galactic today announced the date of its new flight window for a rocket-powered test flight of its SpaceShipTwo Unity.
The flight window will open on February 13 with opportunities to fly throughout February, pending good weather conditions and technical readiness. The test flight will be crewed by two pilots and will carry research payloads as part of the NASA Flight Opportunities program.
Pre-flight preparations are already underway at Spaceport America, New Mexico, including rigorous steps to prepare the vehicles, pilots, teams and facilities, with safety procedures as a top priority. In addition, the Virgin Galactic Pilot Corps has completed two flights with its mothership, VMS Eve, for routine pilot proficiency training. This training included using the mothership to simulate the glide and approach-to-land phase of flight for SpaceShipTwo, showing the versatility of VMS Eve as more than just a mothership.
A key objective of the upcoming flight will be to test the remedial work that has been completed since the December 12, 2020 flight when the onboard computer halted ignition of the rocket motor. The team has since conducted the root cause analysis, completed the corrective work required, and carried out extensive ground testing. The next stage will be to assess and verify this work during a rocket-powered flight.
The flight will incorporate all of the original test objectives from the previous test flight, including evaluating elements of the customer cabin, testing the live stream capability from the spaceship to the ground, and assessing the upgraded horizontal stabilizers and flight controls during the boost phase of the flight.
Following this flight, and in line with normal procedures, the team will complete an extensive data review, which will inform the next steps in the test flight program.
The flight will be conducted by essential personnel only. No media will be onsite, in accordance with Company and state COVID-19 protocols.
Michael Colglazier, CEO of Virgin Galactic said: “We are pleased to be able to get back to the skies and continue our flight test program. I would like to thank our team for their continued hard work and diligence in working towards this important milestone for Virgin Galactic.’’
