The Binuangeun Fish Landing Port (PPI) plays a significant role in driving fisheries activities for fishermen in the Binuangeun area, Lebak, Banten. Despite being the largest fishing port in the region, the facilities owned by PPI Binuangeun have not been optimally utilized. This study aimed to explore the problems associated with the underutilization of operational facilities at PPI Binuangeun. The quantitative research design was carried out by conducting observations and interviews and distributing questionnaires to relevant stakeholders who played a role in the utilization of facilities at PPI Binuangeun. This research seeks to identify problems, constraints, and expected strategies for optimizing the PPI Binuangeun. All the results are presented descriptively. The findings show that the ability of facilities to utilize dock capacity reached 81.8%, that of port ponds reached 89.9%, and that of fish auction sites reached 50%, indicating that the operational facilities at PPI Binuangeun are at an adequate level of feasibility, but their utilization is not optimal. Field findings showed that during 2015-2022, there was a periodic increase in the number of vessels of various sizes, including the number of vessels that docked. Fish production has also increased with an increase in the number of fishing vessels, fishing gear, number of fishermen, production, and production value. In line with this, the manager of PPI Binuangeun must improve the operational efficiency of the port, including optimizing the port's contribution to improving the fishing industry and the economy of the port. Strategic steps are taken to improve the performance and competitiveness of PPI Binuangeun in the future.
Binuangeun 鱼类上岸港(PPI)在推动万丹省莱巴克 Binuangeun 地区渔民的渔业活动方面发挥着重要作用。尽管 Binuangeun 渔港是该地区最大的渔港,但其拥有的设施并未得到充分利用。本研究旨在探讨与比努安金渔港运营设施利用率不足有关的问题。本研究采用定量研究设计,通过观察、访谈和向在比努安岗和平研究所设施利用方面发挥作用的相关利益攸关方发放调查问卷的方式进行。本研究旨在找出问题、制约因素以及优化比南根贡和平研究所的预期战略。所有结果均以描述性方式呈现。研究结果表明,设施利用码头容量的能力达到 81.8%,港口池塘的能力达到 89.9%,鱼类拍卖场的能力达到 50%,这表明比南根港的运营设施具有足够的可行性,但其利用率并未达到最佳水平。实地调查结果显示,在 2015-2022 年期间,各种规模的船只数量,包括停靠的船只数量,都出现了周期性的增长。水产品产量也随着渔船数量、渔具、渔民数量、产量和产值的增加而增加。因此,PPI Binuangeun 的管理者必须提高港口的运营效率,包括优化港口对改善渔业和港口经济的贡献。为提高比南根港的绩效和竞争力,未来将采取战略性措施。

Analytical Prediction for Grain Burn Time and Burning Area Kinematics in a Solid Rocket Combustion Chamber 固体火箭燃烧室颗粒燃烧时间和燃烧面积运动学的分析预测
Q4 Engineering Pub Date : 2019-06-05 DOI: 10.5772/INTECHOPEN.82822

This chapter proposes the application of Newtonian particle mechanics for the derivation of predictive equations for burn time, burning and unburnt area propagation for the case of a core propellant grain. The grain is considered to be inhibited in a solid rocket combu- stion chamber subject to the assumption that the flame propagation speed is constant for the particular solid fuel formulation and formation chemistry in any direction. Here, intricacies surrounding reaction chemistry and kinetic mechanisms are not of interest at the moment. Meanwhile, the physics derives from the assumption of a regressive solid fuel pyrolysis in a cylindrical combustion chamber subject to any theoretical or empirical burn rate characterization law. Essential parametric variables are expressed in terms of the propellant geometrical configuration at any instantaneous time. Profiles from simulation studies revealed the effect of modulating variables on the burning propagation arising from the kinematics and ordinary differential equations models. In the meantime, this mathematical exercise explored the tendency for a tie between essential kernels and mat- ching polynomial approximations. In the limiting cases, closed form expressions are couched in terms of the propellant grain geometrical parameters. Notably, for the fuel burn time, a good agreement is observed for the theoretical and experimental results.
本章提出了应用牛顿粒子力学推导燃烧时间、燃烧面积和未燃烧面积传播的预测方程。假设特定固体燃料配方和形成化学在任何方向上火焰传播速度恒定,认为固体火箭燃烧室中的颗粒受到抑制。在这里,围绕着反应化学和动力学机制的错综复杂的问题目前并不令人感兴趣。同时,物理上的推导是基于假设固体燃料在圆柱形燃烧室中进行回归热解,并服从任何理论或经验的燃烧速率表征规律。基本参数变量用推进剂在任何瞬间的几何形状来表示。仿真研究揭示了由运动学模型和常微分方程模型产生的调制变量对燃烧传播的影响。同时,这个数学练习探索了基本核和多项式近似之间联系的趋势。在极限情况下,用推进剂颗粒几何参数表示封闭形式表达式。值得注意的是,在燃料燃烧时间方面,理论与实验结果吻合较好。

This chapter is the first of two others that will follow (a three-chapter series). Here we present the derivation of the mathematical model for a rocket ’ s autopilots in state space. The basic equations defining the airframe dynamics of a typical six degrees of freedom (6DoFs) are nonlinear and coupled . Separation of these nonlinear coupled dynamics is presented in this chapter to isolate the lateral dynamics from the longitudinal dynamics. Also, the need to determine aerodynamic coefficients and their derivative components is brought to light here. This is the crux of the equation. Methods of obtaining such coeffi- cients and their derivatives in a sequential form are also put forward. After the aerodynamic coefficients and their derivatives are obtained, the next step is to trim and linearize the decoupled nonlinear 6DoFs. In a novel way, we presented the linearization of the decoupled 6DoF equations in a generalized form. This should provide a lucid and easy way to implement trim and linearization in a computer program. The longitudinal model of a rocket presented in this chapter will serve as the main mathematical model in two other chapters that follow in this book.

Industry and market of ballistic protection materials and systems are characterized by a dynamic and competing succession of inventions for projectiles and protective systems. The requirements for the ballistic panels are many and complex, varying depending on the threat type, the required mobility in the tactical theater, and protection level. The safety degree, the price, and the dynamics of research in the field are also taken into account. This chapter underlines the necessity of testing ballistic protection panels made of LFT SB1 plus (multidirectional fiber fabrics, supplied by Teijin) against a certain threat in order to assess their resistance to this specific threat and the investigation of failure mechanisms in order to improve their behavior at ballistic impact. The models for ballistic impact are useful when they are particularly formulated for resembling the actual system projectile, target, and can be validated through laboratory experiments. Tests made on panels made of LFT SB1plus, according to NIJ Standard-0101.06-2008 gave good results for the panels made of 12 layers of this fabric, and the backface signature (BFS) was measured. The BFS upper tolerance limit of 24,441 mm recommends this system for protection level IIA, according to the abovementioned standard.
弹道防护材料和系统的工业和市场的特点是弹丸和防护系统发明的动态和竞争继承。对弹道防护板的要求是许多和复杂的,根据威胁类型、战术战区所需的机动性和防护水平而变化。安全程度、价格和该领域的研究动态也被考虑在内。本章强调了测试由LFT SB1 plus(由帝人提供的多向纤维织物)制成的弹道防护板的必要性,以评估其对这种特定威胁的抵抗力,并研究失效机制,以改善其在弹道冲击下的行为。当弹道冲击模型与实际系统弹丸、目标相类似,并能通过实验室实验加以验证时,这些模型是有用的。根据NIJ标准-0101.06-2008,对LFT SB1plus制成的面板进行了测试,结果表明,由12层这种织物制成的面板效果良好,并测量了背面签名(BFS)。根据上述标准,BFS的上限公差为24,441 mm,建议该系统的防护等级为IIA。

Discrete Element Modeling of a Projectile Impacting and Penetrating into Granular Systems 弹丸撞击和穿透颗粒系统的离散元建模

From theoretical standpoint, it is difficult to analytically build a general theory and physical principles that critically describe the mechanical behaviour of granular systems. There are many substantial gaps in understanding the mechanical principles that govern these particulate systems. In this chapter, based on a two-dimensional soft particle discrete element method (DEM), a numerical approach is developed to investigate the vertical penetration of a non-rotating and rotating projectile into a granular system. The model outcomes reveal that there is a linear proportion between the projectile ’ s impact velocity and its penetration downward displacement. Moreover, depending on the rotation direc- tion, there is a significant deviation of the x -coordinate of the final stopping point of a rotating projectile from that of its original impact point. For negative angular velocities, a deviation to the right occurs while a left deviation has been recorded for positive angular velocities. to
从理论的角度来看,很难分析地建立一个一般的理论和物理原理,批判地描述颗粒系统的力学行为。在理解控制这些微粒系统的机械原理方面有许多实质性的空白。在本章中,基于二维软颗粒离散元法(DEM),建立了一种数值方法来研究非旋转和旋转弹丸对颗粒系统的垂直侵彻。模型结果表明,弹丸的冲击速度与侵彻向下位移成线性关系。此外,随着旋转方向的不同,旋转弹丸的最终停止点的x坐标与初始撞击点的x坐标存在较大的偏差。对于负角速度,发生向右的偏差,而对于正角速度则记录了向左的偏差。来

Adaptive Navigation, Guidance and Control Techniques Applied to Ballistic Projectiles and Rockets 应用于弹道弹丸和火箭的自适应导航、制导和控制技术
Q4 Engineering Pub Date : 2018-02-09 DOI: 10.5772/INTECHOPEN.73511

Accuracy and precision are the cornerstone for ballistic projectiles from the earliest days of this discipline. In the beginnings, impact point precision in artillery devices deteriorated when range were extended, particularly for non-propelled artillery rockets and shells. Later, inertial navigation and guidance systems are introduced and precision was unlinked from range increases. In the last 30 years, hybridization between inertial systems and GNSS devices has improved precision enormously. Unfortunately, during the last stages of flight, inertial and GNSS methods (hybridized or not) feature big errors on attitude and position determination. Low cost devices, which are precise on terminal guidance and do not feature accumulative error, such as quadrant photo-detector, seem to be appropriate to be included on the guidance systems. Hybrid algorithms, which combine GNSSs, IMUs and photodetectors, and a novel technic of attitude determination, which avoids the use of gyroscopes, are presented in this chapter. Hybridized measurements are implemented on modified proportional navigation law and a rotatory force control method. A realistic non-linear flight dynamics model has been developed to perform simulations to prove the accuracy of the presented algorithms.
从这门学科的早期开始,准确性和精确性就是弹道弹丸的基石。一开始,当射程扩大时,火炮装置的冲击点精度就会下降,特别是对于非推进式火炮火箭和炮弹。后来,惯性导航和制导系统被引入,精度与距离的增加脱钩。在过去的30年里,惯性系统和GNSS设备之间的杂交极大地提高了精度。不幸的是,在飞行的最后阶段,惯性和GNSS方法(混合或不混合)在姿态和位置确定方面存在较大误差。低成本的终端制导精度高且不具有累积误差的装置,如象限光电探测器,似乎适合纳入制导系统。本章提出了结合gnss、imu和光电探测器的混合算法,以及一种新的姿态确定技术,避免了陀螺仪的使用。采用改进的比例导航律和旋转力控制方法实现了混合测量。建立了一个真实的非线性飞行动力学模型,并进行了仿真,以证明所提出算法的准确性。
