A heavy-lift launch vehicle (HLV) is an orbital launch vehicle capable of lifting payloads between 20,000 to 50,000 kg (44,000 to 110,000 lb) (by NASA classification) or between 20,000 to 100,000 kilograms (44,000 to 220,000 lb) (by Russian classification) [1] into low Earth orbit (LEO). [2]
For high-level synthesis (HLS or C synthesis), HLV is to HLS as functional verification is to logic synthesis. Electronic digital hardware design has evolved from low level abstraction at gate level to register transfer level (RTL), the abstraction level above RTL is commonly called high-level, ESL, or behavioral/algorithmic level.
The Shuttle-Derived Heavy Lift Launch Vehicle ("HLV") was an alternate super heavy-lift launch vehicle proposal for the NASA Constellation program, proposed in 2009. [74] A 1962 design proposal, Sea Dragon, called for an enormous 150 m (490 ft) tall, sea-launched rocket capable of lifting 550 t (1,210,000 lb) to low Earth orbit.
A potential heavy-lift variant (HLV) of the ULV, in theory was capable of placing up to 10 ton class of spacecraft into Geosynchronous Transfer Orbit. It was planned to include: [22] A larger dual S-250 solid strap-on boosters as compared to the S-200 boosters used in LVM3;
A diagram of the Shuttle-Derived Heavy Lift Launch Vehicle, Block I configuration. The HLV was proposed to be a 4,600,000 pounds (2,100,000 kg) vehicle at liftoff with two 4-segment Space Shuttle Solid Rocket Boosters weighing about 2,600,000 pounds (1,200,000 kg) providing a total thrust of 5,900,000 pounds-force (26 MN) at sea level and the Space Shuttle External Tank weighing about ...
HLV may refer to: Heavy-lift launch vehicle; High-level verification; H-L-V School District, in Iowa, United States; Holland Village MRT station (MRT station ...
Fig. 1. HSL (a–d) and HSV (e–h). Above (a, e): cut-away 3D models of each. Below: two-dimensional plots showing two of a model's three parameters at once, holding the other constant: cylindrical shells (b, f) of constant saturation, in this case the outside surface of each cylinder; horizontal cross-sections (c, g) of constant HSL lightness or HSV value, in this case the slices halfway ...
The Shuttle-Derived Heavy Lift Launch Vehicle (HLV) was an alternate super heavy-lift launch vehicle proposal for the NASA Constellation program. It was first presented to the Augustine Commission on 17 June 2009.
