Re: Vertical Takeoff and Vertical Landing, Now Available for Model Rockets

Powered vertical landings were achieved with model rockets many years ago, and a hobbyist rocket that operates similarly to the SpaceX Falcon 9's first stage (all except the rocket-braked touchdown--this model is covered below) is flying today. Back in the 1960s or 1970s, an American model rocketeer...

Australian sounding rockets paper (links)

Hello All, Below are two different links to an historical paper (which also contains technical information and scale data) about Australia's sounding rockets. It is "Upper atmospheric research at Woomera: the Australian-built sounding rockets," by Kerrie Dougherty at the Powerhouse Museum ...

Re: Sounding Rockets

Also, Barinv (and everyone here), the HAD round that's in the photograph above was one of the several rounds that were launched near Carnarvon, Western Australia in 1964 - 1965 (one of them came straight down...*that* story is simultaneously terrifying and hysterical! :-) ). I have included links to...

Re: Sounding Rockets

Thank you for posting those pictures, Barinv! Another vehicle variation that I noticed is that the HAD (High Altitude Density) round (it's the sounding rocket in the bottom photograph, with a technician next to its LAPSTAR second stage) has its fins affixed directly to the Gosling first stage motor'...

Re: Woomera Rockets - Scale Data

Hey Jason, thanks for posting the scale data, really cool. I'm wondering if the Bloodhound SAM has any detailed scale data associated with it? I reckon it would be a very cool scaled down build. You're welcome, Jase. A bit of it will be published, too (I think I'd be violating confidences to say an...

Re: Mesquito sounding rocket (photos, drawings, and links)

Thanks Jason, that looks like it would make a good scale project...either single stage, boosted dart or 2 stage.... You're welcome, Lamp.

Re: Lightning-triggering rockets! (links)

A correction (of a term): Peter Alway pointed out to me that the term "flaking" (which refers to the way the life-lines of life-saving rockets are packed in their boxes, so that they can un-coil freely as the rockets pull them, as described *here* http://www.cyber-heritage.co.uk/schermuly/...

Re: NASA Detects Force From “Impossible” Microwave Thruster

I'm in favor of research on such unorthodox propulsion devices as the EmDrive and the Mach-Lorentz Thruster (it changes the masses of two "push-pull" masses very slightly by changing their electric charges between piezoelectric push-pull cycles [the presence or absence of the "extra&q...
