Raptor is a family of methane/liquid oxygen rocket engines under development by SpaceX since the late 2000s, [2] although LH2/LOX propellant mix was originally under study when the Raptor concept development work began in 2009. [15] When first mentioned by SpaceX in 2009, the term "Raptor" was applied exclusively to an upper stage engine ...
The Lockheed Martin FB-22 was a proposed supersonic stealth bomber aircraft for the United States Air Force, derived from the F-22 Raptor air superiority fighter. Lockheed Martin proposed its design in the early 2000s with support from certain Air Force leaders as an interim "regional bomber" to complement the aging U.S. strategic bomber fleet, whose replacement was planned to enter service ...
The mixer plays a vital role in the feed production process, with efficient mixing being the key to good feed production. If feed is not mixed properly, ingredients and nutrients will not be properly distributed when it comes time to extrude and pelletize the feed, or if the feed is to be used as mash. This means that not only would the feed ...

The Raptor engine uses a full-flow staged combustion cycle with oxygen and methane-rich turbopumps. [ 27 ] [ 28 ] Before 2014, only two full-flow staged-combustion rocket engine designs had advanced enough to undergo testing: the Soviet RD-270 project in the 1960s and the Aerojet Rocketdyne Integrated Powerhead Demonstrator in the mid-2000s.

Therefore, at a feed mill mixing feed for pigs, for instance, there is still the possibility of cross-contamination of feed going to cattle. [44] Since only a tiny amount of the contaminating prion begins the cascading brain disease, any amount of mixed feed could cause many animals to become infected.
Sod is grown on specialist farms. For 2009, the United States Department of Agriculture reported 1,412 farms had 368,188 acres (149,000.4 ha) of sod in production. [9]It is usually grown locally (within 100 miles of the target market) [10] to minimize both the cost of transport and also the risk of damage to the product.
In April 2024, Musk shared the performance achieved by SpaceX with the Raptor 1 engine (sea level 185 t f, Rvac 200 t f) and Raptor 2 engine (sea level 230 t f, Rvac 258 t f) along with the target specifications for the upcoming Raptor 3 (sea level 280 t f, Rvac 306 t f) [50] [51] and said SpaceX would aim to ultimately achieve over 330 tonnes ...
