| MiG-29 "Fulcrum" |
 |
The Mikoyan MiG-29 (Russian: МиГ-29) (NATO
reporting name "Fulcrum") is a fighter
aircraft designed for the air superiority
role in the Soviet Union. Developed in the
1970s by the Mikoyan design bureau, it
entered service in 1983 and remains in use by
the Russian Air Force as well as in many
other nations.Because it was developed from
the same basic parameters laid out by TsAGI
for the original PFI, the MiG-29 is
aerodynamically broadly similar to the Sukhoi
Su-27, but with some notable differences. It
is built largely out of aluminum with some
composite materials. It has a mid-mounted
swept wing with blended leading-edge root
extensions (LERXs) swept at around 40°.
There are swept tailplanes and two vertical
fins, mounted on booms outboard of the
engines. Automatic slats are mounted on the
leading edges of the wings; they are
four-segment on early models and five-segment
on some later variants. On the trailing edge,
there are maneuvering flaps and wingtip
ailerons.
The MiG-29 has hydraulic controls and a
SAU-451 three-axis autopilot but, unlike the
Su-27, does not have a fly-by-wire control
system. Nonetheless, it is very agile, with
excellent instantaneous and sustained turn
performance, high alpha capability, and a
general resistance to spins. The airframe is
stressed for 9-g (88 m/s²) maneuvers. The
controls have "soft" limiters to prevent the
pilot from exceeding the g and alpha limits,
but these can be disabled manually. In joint
USAF-Luftwaffe exercises, the downgraded
MiG-29 9-12A that the Luftwaffe fielded
defeated the F-16 Fighting Falcon in
close-range combat almost every time using
its highly practical infra-red search and
track (IRST) sensor and helmet-mounted sight,
together with the Vympel R-73 (NATO reporting
name AA-11 'Archer') missile.The MiG-29 has
two widely spaced Klimov RD-33 turbofan
engines

| PhotoTechEDU Day 29: Photographing VR Panoramas |
 |
Google Tech Talks
October, 17 2007
ABSTRACT
Scott Highton, one of the pioneers of virtual
reality photography, will present an overview
of methods and techniques for photographing
VR panoramas. While VR panoramas have become
common for online tours in the real estate
and travel industries, where low-quality
point-and-shoot technique seems to prevail,
Scott focuses on the higher-end and
higher-quality approaches that yield
memorable and evocative imagery.
Scott's talk will include discussion of the
various capture and post-production
technologies available for panoramic imaging
today, as well as a look behind the scenes at
real-life VR photo shoots
Speaker: Scott Highton
Scott Highton is one of the pioneers of
virtual reality photography. He was the
first independent photographer contracted by
Apple to work with and test QuickTime VR, as
well as an early photographic consultant and
contract photographer during the development
of IPIX's PhotoBubble technology.
Specializing in photography of extreme
locations and environments, he was the first
to use both technologies underwater.
Scott has been a commercial photographer,
documentary cinematographer, and writer for
close to 30 years, and is in the process of
finishing his long-awaited book on Virtual
Reality Photography techniques. He has
lectured at a number of photo industry
events, and produces the Virtu...
