 Re-entry vehicle - Wikipedia, the free encyclopedia
A re-entry vehicle is a lander vehicle used in space missions to re-enter Earth's atmosphere safely.
Lunar and asteroid landers are not called entry vehicles as these bodies lack atmospheres, for these see Lander.
Exceptions include early reconnaissance satellites that had reentry vehicles for returning photographic film to Earth and sample-return missions from other celestial bodies (or from open space, as in the Stardust probe).

 Lunex - Chapter 2
Guidance requirements for both the manned and unmanned vehicles can be met with the use of guidance concepts based on the use of inertial and corrected inertial data in a combination of explicit and perturbation computations of present and predicted trajectories.
This vehicle must be capable of returning from the moon and re-entering the earth's atmosphere at earth escape velocity (37,000 ft/sec).
They are not compatible with the velocities associated with re-entry from the moon, with controlled landing, or with manned operations.

 Vehicle Entry
If any vehicle is entered for sale and is sold by the owner or his agent to any person attending the sale, that sale shall be deemed to have been affected by the Auctioneers as Agent for the owner, and full commission will be payable.
Vehicles sent to the Auctioneers for sale and left on the premises are so left at the Vendor’s risk up to the time of sale and the Purchaser’s risk thereafter.
Where a vehicle is purchased which does not comply with the Road Traffic Acts and the Motor Vehicle (Construction and Use) Regulations or any subsequent amendments thereto, the Purchaser shall not remove it from the Auctioneer’s premises under its own power.

 Rudder/Fin Seals Investigated for X-38 Re-Entry Vehicle
This could be of concern because the seals are required to maintain contact with the sealing surfaces while the vehicle goes through the maximum re-entry heating cycle to prevent hot gases from leaking past the seals and damaging interior low-temperature structures.
NASA is developing the X-38 vehicle that will demonstrate the technologies required for a potential crew return vehicle for the International Space Station.
This vehicle would serve both as an ambulance for medical emergencies and as an evacuation vehicle for the space station.

 Boost Glide Re-entry Vehicle
The Boost Glide Re-entry Vehicle was launched from Vandenberg AFB, California to the area of Wake Island in the Pacific Ocean.
Upon re-entry into the Earth's atmosphere, flight control was achieved through the use of the aft trim flares and a reaction jet system commanded from an on-board inertial guidance system instead of by aerodynamic controls.
The test was flown on 26 February 1968 from Vandenberg AFB, California to the area of Wake Island in the Pacific Ocean.

 Re-entry Vehicle, Experimental
I called it the "Re-entry Vehicle, Experimental" or RV-X. I imagined this as the prototype of a general purpose spacecraft that could be used to ferry two astronauts into orbit, as an emergency re-entry vehicle or as a quick response manned military recon craft.
I glued some surfboard foam at the nose of the vehicle, and sanded it to shape.
The cross sections were covered with 0.005" sheet styrene which was glued in place, then trimmed to the contour of the bottom section.

 Remote keyless entry system with advanced activation features - US Patent 6677851
In such systems, an operator can actuate a switch on the keyless entry system, and a signal is sent to a receiver on a vehicle.
Keyless entry systems generate a signal to actuate a security system on a vehicle when keyless entry system is outside of a range of the vehicle.
Thus, the system could be said to provide the function of allowing actuation of a request for a security system unlock on a vehicle from a position outside a range, and then causing the signal to be received by the vehicle, and the security system actuated as the RKE moves within the range.

 13. ATMOSPHERIC FLIGHT
Although the heating and deceleration accompanying atmospheric entry bring about severe design problems, the presence of a planetary atmosphere is advantageous in that it acts as a cushion to reduce a space vehicle's velocity to a safe landing speed.
The chief effects accompanying atmospheric entry are reduction of vehicle velocity accompanied by appreciable deceleration loads and by appreciable heating.
A body approaching a planetary atmosphere possesses a large amount of energy; and one of the most important of the problems of atmospheric penetration is the dissipation of this energy in a manner that will not prove disastrous to the vehicle, either during penetration or on landing.

 Weightlessness - Wikipedia, the free encyclopedia
Weightlessness for a more extended period of time occurs in a spaceship outside the earth's atmosphere, as long as no propulsion is applied, and that it is not rotating about its axis; orbiting the earth this is the case except when rockets are on for orbital maneuvers, and until atmospheric re-entry.
atmospheric reentry, landing on a parachute: gravity is opposed by atmospheric drag
The difference is that gravity acts directly on a person and other masses, just like on the vehicle, while forces like atmospheric drag and thrust first act on the vehicle, and through the vehicle on the person.

 Rednova NEWS Inflatable Emergency Atmospheric-Entry Vehicles
As low as this pressure is, it is at least ten times the expected dynamic pressure on the vehicle during the heating portion of very high atmospheric reentry, and hence it is sufficient to enable the ballute to retain its shape.
In response to the loss of seven astronauts in the Space Shuttle Columbia disaster, large, lightweight, inflatable atmospheric-entry vehicles have been proposed as means of emergency descent and landing for persons who must abandon a spacecraft that is about to reenter the atmosphere and has been determined to be unable to land safely.
Such a vehicle would act as an atmospheric decelerator at supersonic speed in the upper atmosphere, and a smaller, central astronaut pod could then separate at lower altitudes and parachute separately to Earth.
