On-going manned test flights of Boom’s prototype supersonic plane inching towards the supersonic
During the on-going manned test flights of Boom’s one-third scale prototype supersonic plane, dubbed XB-1, the maximum flight speeds have been steadily increased as they company tests the plane’s design and structure.
[On Octoberm 7th on the fifth manned flight] Chief Test Pilot Tristan “Geppetto” Brandenburg set a record for the XB-1 shod with GE J85-15 turbojet engines, taking it up to 17,800 ft (5,425 m) and as fast as Mach 0.69 (428 knots / 492 mph / 791 km/h, true airspeed) over its 50-minute-long test flight, marking the highest and the fastest it’s flown so far.
Boom tested its flutter excitation system (FES) at Mach 0.6 … which must be unnerving for a test pilot. The FES is a system that deliberately induces vibrations into an aircraft’s airframe to help engineers find potential structural issues, particularly at higher speeds. They do this so structural issues (that could cause flutter) don’t rear their ugly head mid-flight.
The plan is to do five more test flights before attempted to break the sound barrier.
At the completion of this testing the company will then begin manufacture of its full scale supersonic passenger plane, dubbed Overture, that will carry up to 80 passengers and will sell to airlines. It already has contracts and financial support from a number of major airlines, including United and Japan Airlines.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
