Higher, Faster, Further

The history of Aéro-Club de France Authors: Marcos Talocchi and Tuomas Simula, Editors Leonardo Times The 14-bis of Santos-Dumont in flight. The Aéro-Club de France was one of the first aeronautical associations in the world, having been founded over a hundred years ago. We explore its history and contributions to aviation, while diving deeper into the life of one of its founding members. CREATION OF THE CLUB Near the end of the 19th century, there were first hints of aviation becoming a feasible means of transport. The first powered and controllable airships were developed, and the first heavier-than-air flights were done using gliders. In Paris, a collective of inventors, industrialists and early aviation enthusiasts saw the need for an organization developing and promoti...

Starship’s Story

The development of a highway to Mars Authors: Marcos Talocchi and Lisanne Vermaas, Editors Leonardo Times Render of Starship in orbit during stage separation. The future of spaceflight is, in short, defined by one word: sustainability. And what other way to achieve it other than leaving single use launchers in the past and embrace reusable rockets? This is what SpaceX proposes with Starship, the first 100% reusable space launcher. Space Exploration Technologies Corporation, or SpaceX in short, was founded by Elon Musk in 2002. His plans to colonize Mars in order to make mankind a multiplanetary species stems from even before SpaceX was founded. After generating his initial capital as co-founder of PayPal, Musk joined the board of the Mars Society and announced Mars Oasis: A pr...

Eyes in the skies

Investigating the ever-growing and flourishing uses of UAVs in agriculture Author: Arham Elahi, Leonardo Times Editor and Naomi Lijesen, Final Editor EAvision’s 30X agricultural drone demonstrating spraying capabilities. Optimizing the agricultural industry is of the utmost importance. Currently, we technically have enough food on the planet to sustain everyone, even though it is tragic that it is not equally distributed. However, the current world population of 7.6 billion is expected to grow by a third, or 2.3 billion, by 2050 - thus, global food production must rise by about 70% to meet this demand [1][2]. Of course, clearing such an enormous area of land to facilitate more agriculture is not a sustainable solution when considering climate change and the strain humans put on t...

Amelia: A Look Back at the Pioneering Aviator.

Author : Katharina Ertman, Editor Leonardo Times On July 2, 1937, Amelia Earhart, in an attempt to circumnavigate the globe, disappeared mysteriously into the expanse of the Pacific Ocean. Somewhere en route from Lae, Papua New Guinea, and Howland Island, she and her navigator, Fred Noonan, lost communications with those on the ground. The circumstances surrounding her disappearance have been the subject of years of speculation and fruitless efforts to determine Earhart and Noonan’s fate. Numerous theories, from sensational rumors, claiming Earhart was a spy for the US government or even she was working for the Japanese government, to more technical speculation, such as the crash-and-sink theory or that she landed on a different island, continue to fuel curiosity. However, the stor...

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 ...

Boeing shows UAV which can Refuel Fighter Jets in Mid-Air

Past Tuesday, Boeing Phantom Works, Boeing's secretive design department, announced a new Unmanned Aerial Vehicle (UAV). Its function is to refuel jets mid-air in order to enlarge the range of combat aircraft of the US Navy. One picture was presented of Boeings MQ-25, showing a slightly blended wing-fuselage design, probably to contain as much fuel as possible. Its V-tail stands out as well suggested to satisfy with the little space available on a carrier deck. While engines are being tested right now, flight testing will be done early 2018. Boeing’s MQ-25 design is their submission for a competition from the U.S. Navy to design a UAV which can refuel fighter jets in mid-air, in particular, to refuel the F/A-18 Super Hornet and F-35, which are already used in the U.S. ...

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...

Drone Collisions More Damaging Than Birdstrikes

Author: Maurits Rietveld, Editor Leonardo Times Birdstrikes have already been an important topic in aviation's safety for a long time. Considering the global rise of drones, collisions between drones and aircraft are starting to play a role in aviation safety as well. New studies have shed light on this issue. A study carried out by the Federal Aviation Administration (FAA) showed that small drones are more damaging to planes than birds. Simulations reinforced by physical material tests were done on aircrafts colliding with drones, varying in weight from 1.2 to 3.6 kilograms. The wing's leading edge, windshield and horizontal and vertical stabilizers were investigated as critical locations. Results showed that the horizontal stabilizer suffered most of the damage and the cockpit’s winds...

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.
