Molniya Triplane Aircraft . At present NPO MOLNIYA is working not only in the space field but also on aircraft engineering. ... Considering this NPO MOLNIYA has chosen a "triplane" aerodynamic scheme stipulating in comparison with traditional schemes the essential increase of flying safety and fuel economy of its aircraft. The triplanes have advantages of canard and classical schemes, but are free from their faults. ... Molniya-1 . ... Heracles Triplane and Aerospace Systems . ...

Next: Black Hole Creation in Up: No Title Previous: Periodic radiosource LSI+61 303 . Several candidates for binary BH with optical companions are known at present (see van Paradijs and McClintock, 1993,[ 208 ] for a review). They must be products of the evolution љ of binary systems with massive companions. Lipunov et al. (1994b)[ 124 ] calculated the expected number of BH+PSR binaries following directly from the modern scenario of binary star evolution using the Scenario Machine. ...
