B-52 Re-engine program

The iconic Cold-war era Boeing B-52H Stratofortress bomber is getting its 1960s-vintage Pratt & Whitney TF33-103 engines replaced by more-efficient commercial replacements. The re-engine program will keep the colossal aircraft operational until 2050 and meet the high-power demands for next-generation weapons, a fire control radar, and other electrical systems. The B-52 is the most combat capable bomber in the U.S. inventory with 76 units completely operational. Due to its high mission-capable rate, large payload, long range, persistence and ability to employ both nuclear and conventional precision standoff weapons. The B-52s has eight engines in four pods, two under each wing. the Air Force overhauls each TF33 every 6,000 flight hours, as a rule, a process that costs $2 million per ...

NASA finds a Solar System similar to our own

Kepler Space Telescope launched by NASA in 2009 to find Earth-sized planets orbiting other sun-like stars has recently discovered a new planet orbiting the Kepler-90 star. This brings the number of planets around the star to eight, the same as the number of planets in our solar system. The star and the system in which the new planet is located is about 2,545 light years away from our planet. There could be more planets in the system which have not yet been spotted. The discovery came as a result of a team effort from NASA and Google Artificial Intelligence. A machine learning algorithm trained to look for signals that might belong to planets played a part in the discovery of the new planet known as Kepler0-90i. Paul Hertz, the director of the  Astrophysics Division of NASA, says  “By ap...

Revival of Voyager 1 after 37 years

The backup thrusters on the Voyager 1 spacecraft fired up after staggering 37 years. It took 19h and 35 min through space for the signal to reach an antenna in Goldstone, California, US, which is a part of NASA’s Deep Space Network. Voyager 1 was launched by NASA on September 5, 1977, 16 days after its twin, Voyager 2. Both these spacecraft are a part of the Voyager program to study the outer Solar System. On August 25, 2012, Voyager 1 became the first spacecraft to cross the heliosphere and thereby making it the farthest a man-made object has ever traveled.  Voyager 1 traveling past the edge of the Solar System.

World’s First Mixed Reality Trainer Developed by Airbus

The unlikely partnership between Airbus and the Microsoft Hololens has led to the development of the world’s first mixed reality trainer for aviation applications. In cooperation with Japan Airlines(JAL), Airbus has developed a prototype for training the mechanics and crew of A35 XWB using the ‘Hololens’ technology and immersive headsets. A considerable amount of resources is focused on training the crew to develop skills required for the operation of the aircraft. This new technology will provide a cost-effective and safer alternative to the traditional training methods. The headsets enable the user to train on an interactive, virtual 3D system while being aware of their surroundings and coworkers. Trainees can access the aircraft digital data which can be viewed from any angle to vir...

China’s C919 Completes Its Maiden Flight

Today, China’s C919 completed its maiden flight, bringing China one step closer to realising their long-standing dreams of having their own home-grown commercial aircraft. The narrow-body aircraft was in the air for 90 minutes before it returned safely to the Pudong airport in Shanghai. Prior to the flight, state television announced that it would be flown at an altitude of 3000 meters and achieve a speed of 300kmph. The flight was cheered on by thousands including dignitaries and enthusiasts.   China has hoped to build its own commercial airplanes since the 1970s when Chairman Mao Zedong’s wife, Jiang Qing, backed a project. The C919 was announced by China nearly a decade ago in May 2008, when they set up the Commercial Aircraft Corporation of China (COMAC). It was initially in...

Aurora unveils eVTOL aircraft

Uber has declared that by 2020 they plan to have a network of ‘flying cars’ in Dallas and Dubai. The new service will be called Uber Air. With Uber Air people will be able to order flying taxis in the same way users of the current Uber app can order car rides. This sounds fantastic and happening so soon! However, during the Uber Elevate summit of April 25-27  2017 in Texas Uber’s chief product officer Jeff Holden admitted that Uber is rushing the Uber Air initiative. Uber Air will consist of electrical vertical take-off and landing (eVTOL) aircraft. Although these eVTOL aircraft seem to be a promising concept, the technologies needed are not yet fully developed. The eVTOL aircraft are envisioned to be fully electric with zero-emissions, autonomous and near-silent. It looks like this vision...

Cassini to perform final series of daring maneuvers

The Cassini spacecraft, part of the international Cassini-Huygens mission, is due to start a series of 22 orbits in between Saturn and its rings today, the 26th of April. The ring plane passages pose the final challenge of the mission: having orbited the planet for the last 12 years the spacecraft is set to enter Saturn’s atmosphere on September 15th. The data gathered in the revolutionary maneuvers are expected to further expand our understanding of the Saturnian environment and the origin of the planet and its rings and moons. Already in 2005 the Huygens probe touched down on the Saturnian moon Titan, which has lead to the insight into its many atmospheric and internal processes. From the combination of the in-situ data recovered by the Huygens probe and remote observations performed...

Printed titanium parts to reduce costs on the Dreamliner

Norsk Titanium AS, a Norwegian 3D printing company, has been hired by Boeing Co. to 3D print structural titanium parts for its Dreamliner. Titanium parts alone cost about $17 million out of the total $265 million cost of the plane. This is due to the 787’s carbon fiber fuselage and wings and result in a higher titanium requirement. This is obviously a sizeable portion of the costs and Boeing has been looking for ways to reduce these costs. Norsk Titanium Vice President, Chip Yates, claims that by 3D printing these, as opposed to manufacturing them the traditional way (with forging and machining), they will be able to cut down the costs of each 787 Dreamliner by around $2-3 million. Considering that Boeing produces around 144 Dreamliners each year on average, this will lead to a sizeable...

SpaceX relaunches a used rocket making history

On March 30, 2017, SpaceX made spaceflight history by reusing a rocket that was used for a previous launch. Their Falcon-9 rocket that was previously used for a mission eleven months earlier, was used to launch the SES-10 satellite. This satellite is intended to provide TV, internet, telephone and radio coverage for South America. The rocket, once launched at NASA’s Kennedy Space Center in Florida, deployed its payload successfully about half an hour later. Following this, it was autonomously guided back to a droneship called “Of Course I Still Love You” that was stationed in the Atlantic and landed safely. SpaceX has been on the path toward using reusable rockets and this launch marked a milestone for them. In the past year, they have managed to recover the first stage of nine o...

Boeing X-37 Mystery Mission

The U.S. Air Force's unmanned space plane X-37 is one of the most mysterious spacecraft ever. It is known as the Orbital Test Vehicle and its primary objective is to test advanced spacecraft technologies. The program is classified, therefore it remains a secret what the tested technologies are. The X-37B was launched on 20 May 2015, this is the fourth X-37 mission and it is still in progress. The X-37B space plane has been in orbit for almost two years now and broke an orbital record when it hit 675 days in orbit around Earth on March 25th 2017.   Concept of U.S. Air Force's X-37B in orbit [NASA Marshall Space Flight Center]   The X-37 program began as a NASA project in 1999 after which it was transferred to the U.S. Department of Defence in 2004.
