Presentation: November 2014

This  months's AE presenter: David Hartman
Date of presentation:  17-November-2014
Subject: the Rosetta Mission
Description: Provided a brief status of the Rosetta mission and Philae probe.
The Rosetta mission reached its goals of intercepting 67P and landing Philae probe on its surface. This was an 11 year mission, and included fly-bys of earth and Mars.  The lander was successful in photographing the surface, but it came to rest in the shadow of a cliff. Lack of power from its solar cells eventually resulted in loss of contact with the lander. The AE presentation included details of he mission including efforts to recover the lander. Photos of the comet were displayed and discussed.

Reports: 2014 2nd Half AE Report and 2015 POA

Two PDFs were submitted to the group AEO on 14-Oct-2014, one containing the squadron's second half ("h2") of 2014 AE report, and one containing the squadron's 2015 AE POA.

These had to be sent out in October rather than January in order to meet the new requirement to switch to the fiscal year rather than the calendar year for such things, and to submit these reports by 15 October.  Therefore the h2 report only covers the period from July - September 2014 despite the "July to December" box being checked.

Aerospace Minute by David

On 6 Oct, David gave an update on the Cessna/Textron Scorpion jet. The Scorpion is designed as a light attack and reconnaissance aircraft.  The news is that Textron is actually flying prototypes at airshows. It was demonstrated at Farnborough Airshow last summer. Textron plans this as an export fighter, so focus is on demonstrating it in Europe.

Presentation: September 2014

This month's AE presenter: David
Date of presentation: 15-September-2014
Subject: The B-58 Hustler
Description: the B-58 Hustler was important for several reasons. It was the first supersonic strategic bomber, capable of speeds in excess of Mach 2. It pushed the state of the art for aerospace engineering, with its first flight in October of 1959.  Finally, it was an icon of the Cold War and nuclear deterrence. It was a delta winged aircraft and required a crew of three. A single thermonuclear bomb and extra fuel was carried externally in a weapons pod. The program was canceled in 1969 due to concerns over cost.

Aerospace Excellence Program

David contacted a Mr Williams, a science teacher at his son's school, to follow up on the Aerospace Excellence program. An email was sent containing information and links, and an offer to help him get started if he is interested in incorporating this into his science curriculum.

Presentation: August 2014

This month's AE presenter: Jeff
Date of presentation: 18-August-2014
Subject: ESA - The Rosetta Mission
Description: Jeff gave his August presentation on the Rosetta Mission, a project launched in 2004 by the ESA (European Space Agency).  Rosetta is a mission to rendezvous with, and enter orbit around, the Jupiter-family comet 67P/Churyumov-Gerasimenko and to perform observations of the comet's nucleus and coma.

An important milestone for this mission was met very recently on 6 August, when the Rosetta craft entered orbit around the comet.  It is expected that the Philae lander will land on the comet's surface in November.

Most of the information and images were taken from the Rosetta Mission's page on the ESA website.

Presentation: July 2014

This month's AE presenter: David
Date of presentation: 14-July-2014
Subject: An Introduction to the Concorde
Description: David gave a presentation that covered the science behind Super Sonic Transports (SST), the international relationships that made the project possible, operations and scheduled flights, and the end of the program. The Concorde was designed with a narrow delta wing to provide better performance and control during transonic and supersonic flight. Britain and France partnered to share the program costs in the 1960's. The program was an international effort which promoted national pride, on the scale of the US space program. British Airways flew twice-daily flights between London and New York. Air France flew once-daily flights between Paris and New York. The final flight was 26-November-2003. The program was ended largely due to lack of financial viability.

Presentation: June 2014

This month's AE presenter: Jeff
Date of presentation: 16-June-2014
Subject: The Great War Gallery
Description: Jeff put together a picture show of sorts illustrating the state of military aviation during "the Great War" (World War I).  Since aviation in general was still in its infancy at the time, a wide range of wildly divergent aircraft was used, ranging from lighter-than-air craft used for observation and, well, spying (with a high mortality rate for the observers, given the wicker baskets and flaky parachutes) to huge biplane bombers that took 23 minutes to climb to 5,000'.

Most of the information and images were taken from an article in Smithsonian Air and Space Magazine about the book "The Great War: A Photographic Narrative" by Mark Holborn and Hilary Roberts (Knopf Doubleday Publishing Group, 10/29/2013).

Aerospace Minute by David

On 2 June, David talked about competition in the market of commercial satellite imagery. Digital Globe currently sells images with a resolution of 50 cm, or about 20 inches. Airbus is selling images with better resolution. They have petitioned for permission to sell images with better resolution and are launching a satellite in August capable of images with 31 cm , or 12 inch resolution. Another challenge for Digital Globe is Skybox. Skybox is a startup that plans to launch 24 low cost, low resolution satellites in low orbit, each satellite about the size of a dorm room refrigerator. Through the use of scale out compute clusters and technologies such as Hadoop Map-Reduce, they are able to create high resolution images by stacking multiple low resolution images. This is a similar technique to stacking photos for astro-photography. It is rumored that Google is eyeing skybox for purchase, we could soon have Google Satellites.

Presentation: May 2014

This month's AE presenter: David
Date of presentation: 12-May-2014
Subject: Burt Rutan's SpaceShipOne
Description: In February, David talked about the career an accomplishments of aviation pioneer Burt Rutan. May's presentation was a in-depth look at his crowning achievement, SpaceShipOne. SpaceShipOne is the first privately funded manned spacecraft. Tech mogul Paul Alan funded the project, the objective wast to compete for the Ansari X-prize. The spacecraft successfully crossed the recognized threshold of space, 100km, two times in two weeks carrying a pilot and sandbags to simulate two passengers. Innovative technology was used including wings and engine. The wings folded upwards to 65deg to allow for a slow, controlled re-entry. This negated the need for extensive heat shielding. The engine was a hybrid, with liquid oxygen as the oxidizer flowing over a core of solid rubber as the propellent. This combined solid rocket motor stability and safety with the ability to stop and restart normally associated with liquid fuel motors. SpaceShipOne made three flights, and now hangs in the Smithsonian's Air and Space Museum.

No Presentation for April 2014

Due to other activities at Squadron 80 during the month of April 2014, there was no Aerospace Education presentation given at the squadron during that month.  This is not to say that AE as a general area of discussion was neglected, but no specific presentation was given.

On 31 March, David talked about the Air Force's efforts to save fuel through formation flying. Birds fly in formation to save energy, same concepts can be applied to aircraft. The Air Force found that C-17s can save about 10% on fuel consumption by flying level with the lead aircraft, 140 feet to either side, and 7000 ft spacing. Two test flights from Hawaii to the mainland resulted in the saving of 7000 lbs of fuel. Use of this technique requires relaxing delivery schedules so multiple aircraft can be flown at once. Also, additional avionics will be helpful. Aircraft considered for this program include the C-17,KC-135, KC-10, C-130, C-5, and F-16. Of special interest is flying fighters in close formation with their tankers on long ferry missions.
