| 101 | Apparatus and Method for Aerodynamic Drag Reduction | PCT/GB2011/050234 | 2011-02-09 | WO2011098807A1 | 2011-08-18 | QIN, Ning |
An apparatus and method for reducing aerodynamic drag is disclosed. The apparatus and method is adapted to reduce wave drag and profile (form) drag associated with aerodynamic bodies, wings, rotor blades, or other aerodynamic surfaces operating in the transonic regime. In one embodiment, a three dimensional bump (100, 500) is disclosed, adapted for location on the surface of an aerodynamic body, having a curved upper surface (120, 140, 160, 180, 200) which redistributes the pressure of a normal shockwave generated on the aerodynamic body and at least one integral vortex generator (300, 550) arranged to generate a stream-wise vortex downstream of the bump. The combined effect of the bump (100, 500) and the vortex generator (300, 550) is to reduce the wave drag associated with the shock wave and to avoid or delay the post-shock boundary layer separation, thereby reducing form drag. |

An apparatus is provided for reducing aerodynamic drag experienced by an over- the-road vehicle while underway. A frame assembly including a fastening fixture couples the apparatus to the vehicle, and a first airfoil including a first outward air deflecting surface deflects a portion of the airflow directed toward a first tire laterally outward toward an externally exposed side of the first tire. A second airfoil including a second outward air deflecting surface deflects a portion of the airflow directed toward a second tire laterally outward toward an externally exposed side of the second tire. The first and second airfoils are spaced laterally apart from each other when coupled to the vehicle by the frame assembly to define an aperture between the first and second airfoils through which at least a portion of the airflow directed toward the axle assembly is to pass while the vehicle is underway. |

| 103 | Aerodynamic resistance weld pin | US09989766 | 2001-11-20 | US06497543B1 | 2002-12-24 | John Lyons |
| A resistance weld pin for connecting batts of insulation to the interior of ducts is disclosed, the pin having superior aerodynamic properties which minimize turbulence in the duct flow stream and reduce the tendency of increments of the insulation surrounding the pin will become separated from the main body of the bott when introduced into the air stream. The pin assembly comprises a washer and a pin component projecting through the washer. The upper surface of the washer includes an annular depressed trough surrounding the head of the pin. Preferably the head is disposed within a central depression in the washer, the upper surface of the head forming a contact surface for the applying electrode and lying in a plane above an annular platform extending between the trough and the depression. | ||||||

| 본 발명은 고속 열차의 전두부 차량의 구조를 개선하여 고속 열차의 주행시 발생하는 공기저항을 저감함으로써 주행성능을 향상시킬 수 있는 고속 열차의 가변 딤플형 공기저항 저감장치에 관한 것으로; 고속 열차의 전두부에 일정간격으로 형성되는 다수의 딤플과, 상기 고속 열차의 전두부에 상기 딤플을 커버 할 수 있는 가림부와 딤플이 공기중에 노출되도록 하는 개구부가 교대로 형성되는 커버체;로 이루어지는 것을 특징으로 한다.
본 발명에 따르면, 고속 열차의 전두부에 딤플(dimple)을 형성하여 열차가 주행시에 딤플에 의해 난류경계층이 형성되며 열차표면에서 유동 박리가 뒤쪽에서 일어나게 되어 딤플이 없는 전두부보다 유동박리 후의 후류 영역이 작아져 압력저항을 줄여주어 공기저항을 줄이는 효과가 있다. 특히 주행중 공기저항을 줄여줌으로써 열차의 주행을 위한 에너지 낭비를 줄여주고, 선로 주변의 소음 및 차내 소음 역시 줄여 줄여주는 효과도 있다. |

| An exercise apparatus combines weight and pneumatic resisitance to provide a user with options to work against either or both type of the resistances. In one mode, the exercise apparatus includes a user interface, such as, for example, a weight-lifting bar, that a user can move either toward or away from stationary portion of the user's body. A weight (e,g., a free weight plate) can be selectively coupled to the user interface. A pneumatic resistance device can also be selectively coupled to the user interface independent of whether the user interface is also coupled to the weight. The pneumatic resistance device includes at least one valve to regulate the amount of the resistance that the pnuematic resistance device applies to oppose movement of the user interface in at least one direction. At least one actuator may be provided for controlling the at least one valve, the actuator being configured to be manipulated by the user while the user is in an exercise position. The apparatus can also include a trolley that moves relative to a track. The trolley can move with the user interface so as to permit various positions of the user interface relative to the pneumatic resistance device. An adjustable bench adapted to support the user during exercise and capable of engaging an auxilliary rack assembly may also be provided. The bench includes a seat and a backrest that are interconnected and moveable relative to a frame. The bench is adjustble from a generally flat configuration to one or more inclined configurations. In the Flat configurations, the bench is particularly suitable for pressing exercise such as the bench press. In the fully inclined position, the bench is suitable for upright exercise such as the military press and the shoulder press. The shoulder of the human body remain generally at the same horizontal location along the bench as the backrest is inclined. The bench thus does not need to be repositioned relative to a bar as the inclination of the bench is changed. | ||||||

Eine Gasfeder mit Endlagendämpfung weist ein mit unter Druck stehendem Fluid gefülltes zylindrisches Gehäuse (2) auf, in dem eine aus einem Ende des Gehäuses abgedichtet herausgeführte Kolbenstange (4) koaxial verschiebbar angeordnet ist, an deren innerem Ende ein Kolben (19) angebracht ist. Um eine in ihrem Aufbau einfach Endlagendämpfung zu schaffen, die sowohl rein pneumatisch, als auch rein hydraulisch, als auch hydropneumatisch wirksam sein kann, ist auf der Kolbenstange (4) verschiebbar ein als Drosselkolben ausgebildeter Zusatzkolben (28) angeordnet, der über einen Kraftspeicher (29) zum kolbenstangenaustrittsseitigen Ende des Gehäuses (2) hin abgestützt ist. Der Kolben (19) kommt am Ende der Ausfahrbewegung der Kolbenstange (4) zur Anlage an diesem Zusatzkolben (28). Dessen Drosselwirkung ist beim Verschieben zum kolbenstangenaustrittsseitigen Ende hin größer als in umgekehrter Richtung. |

A pneumatic ventilation system delivers high amplitude, low frequency oscillatory flows while maintaining the load impedance at a specified mean pressure, thereby accurately controlling mean airway pressure, oscillation amplitude, and frequency content allowing use in applications to optimize high frequency ventilation protocols in patients. The pneumatic ventilation system includes a pneumatic pressure oscillator based on a proportional solenoid valve (20) to provide forced oscillatory excitations to a respiratory system over a bandwidth suitable for mechanical impedance measurements and high frequency ventilation. |
